Endogenous Empiricism


The trip to Guinea-Bissau comes without any pretext of architectural or ethnographic research, it comes from stories and sparkles in the eyes, sighs that convey states of mind. In the inevitable Bissau, however, one can foresee a warm vernacular culture, much obfuscated by the search for an international development that alternates with the Portuguese melancholy that in obsolescence insists on resisting.
Among other places, I found the island of Elalab, an island among the mangroves full of vast bolanhas interpolated by small and lively villages, in a harmonious ecosystem. In this place, life is the present. the day, once hostage of the future, emerged as the meaning of life, as the reason for the upcoming. The constancy of imminent death due to the absence of means creates a collective conformation of the ephemeral condition, generating a kind of humility and transversal bonhomie. This condition helps to qualify the place as something supreme, a consideration that is certainly not disassociated with the fact that the Felupes is an originally animist ethnic group. However, all resources are endogenous, everything revolves around the activities that the land provides. This inextricable reality elevates the place to the essence of human life.

Architecture no longer refers to the place, it is the place. Here, the architecture is the clearing and the grove that organize the implantation; it is the earth and the water that become the rammed earth that creates the envelope for the fresh spaces; it is the mangrove wood and the fiber of the palm tree that intertwined, structure the limit and cover through which the air circulates; it is the rice stem that provides the culm that protects from the rains and shade from the sun; it is the wood of the poilão tree that sculpts the canoes and doors; it is the community that comes together in an artisanal process perfected by time.

In Guinea – not – Bissau, I let myself be carried away by the movement of the sun and the slower speed of time, which allowed me to calmly absorb the surrounding reality, recorded by drawing and photography that, due to their inert nature, become reductive. However, they allow us to understand how through an empirical process these communities develop a sustainable architecture, using passive methods and local resources that, intelligently arranged with simple constructive systems, through a self-built process, create functional and comfortable spaces for living.

Superego Emergency


The present reflection appears as a tribute to our moral unconsciousness and its consequent extraordinary elevation in a particularly difficult and unprecedented context in the temporal space of today’s humanity: the conditioning of the dynamics of life, based on the emergence of a pandemic. The moral values that emerge from the vast sea of our mind were the motto for an expressive manifestation of thoughts supported on an idiosyncratic referential basis.

The situation suddenly took over our reality, and, immediately, a “war” against a virus began, which materialized in several actions, perhaps the most impacting being the infamous confinement. Much has been discussed about the value of the word war in the current context. However, any belligerent, perhaps sometimes dysphemic, lexicon reveals only the great visible impact, paradoxically of invisible origin, in changing sociological behavior paradigms. In turn, this change, despite being sensibly and transversally accepted, is politically imposed, which raises the fear of the resurgence of some type of autocratic movement that could jeopardize values as important as democratic freedom. This wasn’t the case in Portuguese reality. Nevertheless, the imposition of physical and social confinement is real, such as the transformation of daily dynamics. The very condition of the present essay represents a reaction to the imposition.

Curiously, in a context of forced isolation in which introspective time multiplies, and, being subjective expression the exponent of our freedom, we have never been analytically so free. It is in this duality between expressive freedom and physical confinement that the impulse of a personal manifestation arises, something recurrent in history. Dostoevsky, for example, wrote some of his works confined in prison, which consisted of literary allegories that were based on existentialist thoughts and Russian society. Also, reflective manifestos hardly spring from an instantaneous flippant genius. The questions, the themes, and the problems are debates that are already present, intermittent, and repressed by the speed of everyday life.
Its development is only catalyzed, and, the result is presented only as a synthesis of a longer process. In the specific context of the current pandemic, as evidence of this analytical opportunism, there is Bob Dylan’s musical eulogy, “Murder must foul”, released on March 27, 2020, based on its maturity of cultural references over one of the most popular political plots that ever existed. This theme was surgically presented at a time of world calamity, revealing almost a premonitory sense whose advent is intellectual, but above all analytical.

It is attached to this reflexive logic, supported by a continuous critical analytical spirit, that this reaction to a specific event arises. Long before its reproduction, its aura was already being defined – using Walter Benjamin’s term – even if still unconscious. As mentioned initially, the moral values that emerge from the vast sea of our unconscious, whose depths are full of potentially harmful emotional impulses that in these moments easily trigger, were the motto for a formal materialization of already existing reflections and references.

In an analogy to the organizational triptych system of the human psyche according to Sigmund Freud, composed of the Ego, ID, and Superego, a subjective interpretation of the unconscious impulses triggered by the pandemic is proposed, with an abstract representation that is materialized through an illustrative architectural lexicon. Explaining the concepts referred would be reductive and tautological. However, it is important to associate them simply, with ideas and feelings, to make the formal motives perceptible. In this sense, we can define the Ego as the ontological “I”, as the closest instance to reality, associating it with reason; the ID to primitive emotions, drives, and the search for immediate pleasure; the Superego to the moral conscience, to the emphasis of the values and ideals of the society in which we are inserted. In the 3 stages of our mind (unconscious, preconscious, and conscious), the ID is inscribed in the unconscious, while the Superego oscillates between the unconscious and the conscious, with the Ego being the instance that is normally present in our conscious.

A morphology begins to emerge that interprets the movement of the collective unconscious through the alteration of social dynamics in the period of confinement. The result is an idea of a tripartite construction within the three levels of our mind, with three volumes that represent the three instances that constitute it. Each volume is associated with a primary color, as a De Stijl action, in a completely intuitive correspondence, linking the fiery
red to the impulsive ID, the illuminated yellow to the nuclear Ego, and the recessive blue to the dormant Superego. The Superego,
little conscious, temporarily gains, in the light of the pandemic reality, a growth that figuratively overlaps the Ego. The installation, imagined as a walkable construction, allows us to go through the three instances culminating in the blue and bordered “tower” of the Superego, crowned by the resplendent “sun” of the Ego, in an analogy that alludes to the different feelings and emotions aroused by the pandemic since the beginning until the end of the national state of emergency, ending with the exhortation of moral values over primitive immoral impulses that give in to selfish visions of self-pity and put aside collectivist and solidary visions.

We are facing one of the biggest psychoanalytic conflicts of our unconscious, and without realizing it, the collective meaning seems to emerge responding to the call of necessity. Our State has determined the Emergence of our Superego. Quarantine presents itself as the real health consequence, evoking psychic punishment and social responsibility. In turn, its ephemerality refers to the transitory process of psychic balances and imbalances, which means, it represents an unbalanced sociological state that is both penitential and restorative, presupposing a healing process. This reflection is crystallized through the proposed architectural form, as a subjective symbol of an individual reading.

“When the subject can choose between several symbols to represent a certain content, he will decide on the one that also has objective relations with his remaining ideological material and, therefore, allows individual motivation.”

FREUD, Sigmund, Author translation from “A Interpretação dos Sonhos”, pg 255

The general narrative described can be divided into several phases, at different moments that aroused different feelings and reactions. The illustrative map that is presented is precisely a survey of the parabolic path that we all live, but in a subjective representation and with an allegorical construction according to the Freudian psychic apparatus. In his conception, sometimes in parallel, sometimes later, many times before, the rhetorical mapping that guides the arrangement and order of the nine defined illustrations emerged. Its composition and organization can be subject to multiple interpretations, but the presentation follows the narrative script that accompanies it, a concept totally in keeping with personal experiences. There won’t be an explanation of the compositional organization of the map because, for that, the adjacent narrative already exists. However, it is essential to explain that the different illustrations are composed of different architectural representations of the allegoric base, referring to the emergence of the Superego, arranged in such a way that, subjectively, they refer to a relationship with the words chosen for the nine phases identified, respectively: Pugna (fight); Melancholy; Order; Isolation; Neurosis; Noesis; Hope; Abnegation; Catharsis.

These illustrations appear as a graphic analogy, in a somewhat suprematist way, to the dynamics of the psyche spectrum, based
on some psychoanalytic concepts, in an idiosyncratic interpretation, juxtaposing them to the complexity of mental behaviors observed and felt in the context. of the current pandemic.

“the analogy establishes the conception, merging memories and images to give rise to the project. This process involved architecture in layers of content foreign to the discipline and used its results for narrative and poetic purposes. So shaped, construction was the mere objectification of an idea or image.” 2

LOPES, Diogo Seixas, Author translation from “MelancoliaeArquitecturaem Aldo Rossi”, pg 247


A kind of Cartesian logic underlies this whole mental process, as well as its final result, an unsettling desire to question and participate, fostered a Cosa Mentale that can manifest itself in infinitely different ways. These representations appear above all as testimony and questioning, but also as a subjective answer to the questions of the possibilities of the state of mind in a shocking situation like this. On the other hand, it refers to a nostalgic and laudatory attitude towards the community, even though temporary confinement can have a cathartic effect that is often necessary. It could be said that many of the issues raised by this pandemic are, in part, exacerbated by the subsequent reflection, which manifests itself formally in an allegorical way, through the reuse of concepts and their resignification, a little like the ready-made of Marcel Duchamp, although in this case,

the shape is original. The result appears to be a conscientious phenomenological exercise, while the formal lexicon is undoubtedly architectural; however, the expression is pictorial.

Thus, confinement, paradoxically, encourages us to enjoy expressive freedom. Its awareness, in a certain field, whose anticipatory component is strong, as is the case of art or architecture, works as an analytical fuel that feeds our creative engine. The resulting material appears as a form of an individual process, an intermittent process, interspersed with drawings and notes, this being the only text produced continuously, in the form of an explanatory epilogue. Its process confides legitimacy to its questioning, confides fear to its fragility, but above all it confides freedom of thought, and an operative impulse that yields to temptation and manifests itself. Architecture appears as a representative tool in the realization of this (psycho)analytic process.

“How far from our consciousness are these things that rule our unconscious psychic life!”3

FREUD, Sigmund – Author translation from the afterword of “Os Irmãos Karamazov” of Fiódor Dostóievski, pg 775

Bairro do Leal AppropriationPorto2021

Bairro do Leal Appropriation


The ‘Bairro do Leal Appropriation’ workshop is part of an endeavour to raise awareness of the precarious nature of life in Porto’s urban interstices. The neighbourhood’s obsolescence and expectant character offered a starting point for reflecting on, designing and transforming a concrete place over a period of one week.

Social interaction between the team of young participants and the local residents played a key role in the architectural action. Following visits and discussions, a fenced off plot that had been abandoned for years and was once occupied by houses was identified as the intervention site. The absence of a green space for public use in the area was another reason for salvaging and improving the plot. Via a participatory process of self-building, the plot was appropriated and revitalised.

The first step was to remove the fence around the plot and to tame the wild, unkempt vegetation. This revealed the site’s physical and topographic characteristics: its slope; the concrete joists marking its outer edges; the ‘amphitheatre’ created by piles of granite rubble from the former houses; the butchered trunk of a eucalyptus tree; the leafy lemon tree; the gable of the neighbouring house; the ruins still standing and the makeshift shelters for stray cats (the site’s only ‘residents’).

In the next step, scale models and designs were produced to explore ways of appropriating the plot via small-scale actions and constructions that would foster new uses. The process was interspersed with talks by speakers with experience of participatory projects and self-building initiatives in vulnerable neighbourhoods in different contexts, and critiques with guests whose knowledge shaped our approach to the evolving project.

A series of operations with different scopes and scales was launched, based on our ongoing presence at the site. The intention was to use the entire plot to create a new ‘house’ with different ‘rooms’ suited to different functions. A small stage was built to supplement the ‘amphitheatre’, providing opportunities for small events, performances and meetings to be held. Using wooden beams on the flattest part of the plot, a structure to provide shade was built along with benches and a large table to encourage people to meet for gatherings and meals. A rest area was created in the shade of the lemon tree; shelters for cats were renovated; a former kitchen was given a new use as a support area for events, and the fence that had been removed was repositioned in the middle of the plot, symbolically evoking the trunk of the eucalyptus.

New and old elements were painted in the same colours as the adjoining houses (beige and red), lending a sense of continuity to the site and embodying the intention to extend it into Bairro do Leal and establish a dialogue with the surrounding area.

The workshop ended with a gathering with residents, neighbours and participants, which included performances, graffiti, food and an open-air cinema session. At the event, residents were invited to look after and appropriate the plot.

In subsequent weeks, neighbours created their own ‘urban furniture’, restored a concealed floor, planted a variety of plant species and laid out small stones to give a sense of belonging. Months after our intervention, the municipal gardening team regularly visits and cleans the plot. The new local dynamics are illustrative of the positive impact that small-scale actions can have in improving degraded or unused areas within the city.

Coimbra Vague


How can architecture act in the terrain vague without becoming an aggressive instrument of power and abstract reason?1

Terrain as a place that presents itself in an expectant condition, potentially usable but adding a limit in its relation to the surroundings. Vague as lack of definition or lack of use, a condition of possibilities that allows a sense of operational freedom. This concept, theorized by Ignasi de Solà-Morales, arises from the focus given by photographers and artists on marginal and obsolete terrains that seemed empty of meaning. These interstices appear as absence and limit, and at the same time, paradoxically, as promise and expectation. They present themselves as the resolutive catalyst for the spatial intermittences caused by the major plans, contributing to the city limits’ loss. It’s not a surprise that these spaces are assumed today as structural in the analytical process that precedes the intervention of urban design.

In this way, the terrain vague concept, in a specific context, refers to any circumscribed territories, which for several reasons have been forgotten or undefined, a situation often resulting from the actions of the modern movement supported by the sharp and imposing technocracy that marked the 20th century.

In cities like Coimbra, the topography is the major circumstance of any type of intervention in the territory. It defines not only the architectural typologies but also urban collective strategies, namely the use of public space and mobility. The isolated traces from the past, based on a logic of development through the extension of the main axes, with a design that circumvents the contour lines, enhanced an altimetrically fragmented territory, creating undefined urban interstices that invoke action. The morphology and scale of this kind of places is diverse, however, the expectant character is what unifies the general problem.
Paradoxically, it’s the divided and alienated character of these spaces, along with their central and circumscribed position, that enhance their agglutinating role towards a rhizomatic and continuous territorial structure.
The indefiniteness of the green area that is limited by the streets Nicolau Chanterene and Padre Manuel da Nóbrega, in the city of Coimbra, evokes the possibility of intervention and requalification of an expectant space full of meaning, a large Terrain Vague with almost 95.000 sqm, surrounded by a high population density, but with no use or interaction with it. Furthermore, this space offers a possibility of optimizing pedestrian mobility, searching for solutions for the problem of zigzagging paths often exclusive and ending in cul-de-sacs, creating “islands” or “peninsulas” of expectant lands.
To envision a possible solution to this large space, firstly, it was extremely important, on a bigger scale, to understand its location/position in Coimbra, the access and connections into and from it, and the relation and proportion with the existing urban parks around the city. Then a deep analysis of the plot itself: a valley with an extreme topography, surrounded by the housing buildings turned back to the plot, even blocking the access to the inner space by their garages, poor constructions, working as authentic barriers of use. And finally, a closer look at the Yellow House ruin and the historical evolution of the pathways from 1934 to the present neighborhood.

And finally, a closer look at the Yellow House ruin and the historical evolution of the pathways from 1934 to the present neighborhood.

By the end of this analysis and with the intervention of all guests, the program of an Urban Park, catalyzed by the existing waterline came up as the strategy for the entire plot. The waterline, together with the most flatted areas, became the center of the design, associating all the programs that potentially can change the current lack of use of a high-quality green space, enabling its constant use by the locals as well as all Coimbra inhabitants. It was proposed a playground and a new housing block at the east entrance, a sports court, a cafeteria, and a cold greenhouse facing an artificial lake in the most central area of the plot and an area for urban farms. Combined with a new structure of pathways (both existent and new), the open waterline and the new program can generate new living dynamics at the lower level.
To solve the problems of mobility and the need for a fast crossing through the plot, another strategy rose: a transversal connection at a higher level. Taking advantage of the topography two main points were chosen: on the north side, an existing square and cul-de-sac that serves the housing buildings, and, on the south part, the Yellow House plot. In both areas were integrated new programs and designed new public spaces, serving at the same time as entrances and places to use: at the north, facing south, the warm greenhouse and a public square above it, and in the Yellow House, a new cultural and educative hub related to the greenhouses.

Connecting the two sides, a pedestrian bridge was designed both to cross and observe the view. Finally, after analyzing the existing types of greenery, a new density of trees is suggested to create different areas along the site: a mass of trees in the most aggressive topography, along the pathways and behind the cold greenhouse for shadow, and a lower scale of greenery, with open areas along the waterline and the programs related to it. Planning the location and density of the new trees in close relation to the new volumes guided and concluded the final proposal.
The analysis, ideas and design proposed on this specific plot are just an example of what can be thought and developed in several other Terrains Vagues spread around city centers, rising their structural potential instead of just assuming them as a problem. The possibility of new connections and new uses encourages urban development, just as new programs can promote new social dynamics. It is on this dichotomy that architecture acts, assuming itself as an instrument of intellectual support that allows analytical thinking first and morphological action after, to guarantee a more sustained intervention on the territory.

Leote do Rego

Collective Housing


The city is always an anachronistic home for the newcomer. Its built ecosystem reveals disparate forms that reflect the narrative of the time. Thus, demiurges, circumscribed to their formal ontology, dream the bodies.

The new is a hybrid and multifaceted being that emerges in a conflicting scenario. The multifamily ancestry is numerous and determines the altimetric scale, but it is the small and old being that wistfully defines its expressions, and, in this way, avoids its disappearance in time, if not physical, at least memorial. Its body members are an apology for poor relatives, the forgettable industrial bastards with a fragile umbilical cord that connects them to their urban mother. Their connection, however, is strengthened and replicated, lighting the way on the one hand, and countering its apparent uselessness on the other hand.

The inexorable telluric circumstances are apprehended in the necessary functional mechanics, in a general configuration whose purpose is a kind of metaphysical harmony amplified by the geometric-spatial gnosis. The arithmetical ingeniosity, fed by the territory genetic code, overlaps the beauty of the congenital scribble, the intuitive organicity of nature’s design. The morose and atrocious tenacity of a frowning face reappears in the splendor of a geometric smile that does not hide its process. On the contrary, it is assumed as a seed of its alacrity.

The form is consequent; action on a problem that determines a new problem and a new answer, in a cascade of decisions that, despite coming from the rational, look ascetically defined. Determination is an immersive, one-way journey between scales and space; the tangle of information is embodied in an organism where the program descends from the facade and the threshold is the grandchild of the implantation; All the components are part of the inextricable constructive machine that connects them to the future, in a experimental melody that separates itself from the fainthearted conformation of ease.

Praça Central da Vila de Manteigas

Public equipment and urban planning


Designing the new Manteigas Square is defining a territorial reference, a point of convergence between the mobility network and the town by creating a new town gateway. It’s about creating a relational system that at the same time creates spaces for permanence and articulates the main road to the historic center, resolving the difference in elevation. It means building a place of community where everything that is part of it can happen there, an identity.

The area of intervention claims its distinction from Rua 1º de Maio, the axis of arrival for those coming from the east. The boundary of the wall is replaced by a new front with a bench in the sun and a staircase that sets off a harmonious path through the different spaces, culminating in the square at a high level, headed by the pre-existing stone staircase
which sets the tone for the design.

The new square is unified by the design of the pavement, which determines and conceals the traffic flow. The visually disconcerting wrap, once the protagonist, is topped off by a new volume that consolidates its centrality by creating a new front for the square. This building solves the requested program, namely parking, by operating as a functional element that makes the transition between the three main levels, guaranteeing accessibility for all.
Like Francis Towne’s Temple of Concord, the porticoed structure, whose formal identity is related to the Roman presence in the town, calls for universal appropriation with no predefined function other than to mark the transition from the street to the forum, from the street to the square. Its importance lies in its ability to serve the public space in a flexible and transversal way by generating spaces that enhance local dynamics while at the same time encouraging external visits.

The design of this place was based on the memory of restful conversations under the shade of the trees, the games of cards and dominoes that characterize the squares, the summer concerts and fairs under the warmth of the granite, the Sunday afternoon promenades between whitewashed houses. This drawing is the becoming of a place for everyone!

Private Housing


The site earmarked for intervention presents itself as a lost island amid the sea of informal constructions developed during the industrial period. Despite its density, it stands isolated, set back from the street front, with an almost invisible access, concealed by the mystery of its challenging accessibility. The path is narrow, measuring 1 meter in width and 45 meters in length. At the end, we reach a door and are greeted by surprise. The space is expansive, with an even broader prospect.

The construction, of uncertain date but already documented by Telles Ferreira in 1892, pre-determined the layout. The diachronic occupation of this area carries underlying layers of memories and sentiments that characterize the complex Porto identity matrix. The first design action was archaeological. The anatomy of the stone skeleton that supported various lives was dissected and revealed. The primitive construction method thus gains a new formal protagonism that contrasts with the necessary excerpts of the new usage, in an ode to the palimpsest logic of the city. A hybrid whose beauty lies in an operation between scars and excerpts, the new subtly overlaying the old.

The new wooden structure, a dry and prefabricated system strategically chosen to facilitate construction logistics, delicately rests on the centuries-old masonry, evoking the original tectonic quality. Truncated at both ends, either for a terrace or a porch, it is elegantly crowned by an overhanging eave, akin to a tightrope walker’s pole.

The ground floor, more utilitarian, is divided into two sections, one private and the other social. To the north, embedded in the slope, we find the private area, a bedroom extending to the sanitary installation, a finely designed marble piece. To the south, a social area, including the kitchen and dining zone, with a new opening that strengthens the connection to the garden.

The central double-height space and the wooden staircase descending from it are a prelude to a more open and light narrative about the exterior. Upstairs, everything is spacious and flexible, with curtains that compartmentalize uses according to desires.

The house aspires to fulfil the desire for tranquillity of its owners, a refuge of peace at the core of a thunderous reality.

Fernão de Magalhães

Collective Housing


The plot aimed for intervention is a corner on Av. Fernão Magalhães, one of the main urban arteries of Porto, which is characterized by its morphological heterogeneity. The plot’s surroundings are composed of buildings with dissonant architectural languages built throughout the 20th century, as well as a discrepancy of scales, namely in the transition with its transversal axes, predominantly defined by single- family typologies of the 19th century, a situation exacerbated by the strictness of the regulations in the urban corners’ transitions.

The proposal is a formal and typological laud for this confluence of apparently belligerent realities, which intends to prove the possibility of their coexistence in harmony, always in close relationship with the place.

Planimetrically, two typological actions are defined, physically separated: a collective housing block that forms the corner
and extends 15 meters on the transversal street, subverting the regulations and solving the inevitable altimetric transition; a set of
3 houses that evoke the collective memory of the single-family typology predominant on the street.

Altimetrically, 3 formal and material moments are presented: on the first level, an in situ concrete base that defines the intervention area; on a second level, facades in prefabricated concrete that dialogue with the construction period with granite of the 19th century and the first half of the 20th century, namely on the 2 floors of the houses’ facade and on the 3 floors of the protected building to the north; on the last level, an expanded metal sheet facade, in a more contemporary language, turned to the 21st century.

The entire building is designed using a rigorous metric that organizes the interior spaces and is reflected in the facades. The main stairwell coils in height, connecting to the north facade on the residential floors, allowing the social spaces and bedrooms to face the common patio to the south, or east and west, while kitchens and sanitary facilities face mainly north.

Praça das Companhas

Public equipment and urban planning


The commission is part of a macro urban plan to redesign the seafront of Esmoriz and Cortegaça. The intervention area is Praça das Companhas, the tail-end of the main access axis that reaches the beach, and representative space for“Arte Xávega”, an activity that shaped the development of the community and the built territory. The project appears on two levels. First, to enhance the fishing activity through the creation of a dynamic program. Second, to qualify the seafront, not only by returning the visual relationship that is now non-existent, but also with the renaturalization of the dune, with programs such as surf, tourism, and restaurants, which can and should coexist with fishing activity.

Thus, the proposal is characterized by a simple gesture on three levels: a raised platform that restores the views towards the sea; an intermediate level next to the seawall and access to the beach; and the lowest level related to the street. Consecutively, this action is divided into 3 zones: north, the end of Avenida da Praia with the viewpoint tower and a new square that works as a transitional hinge between the 3 levels of the route; the central one, with a built volume in concrete, with a constant and adaptable metric, allowing
a flexible and floodable program such as a market, lockers, public restrooms, and parking, while at the higher level, a promenade route is related to the sea; to south, the building is crowned with a volume that houses a bar/restaurant and shop/surf school, defining the access to the beach, and making the transition between the dune and the wooden fishermen’s support equipment. Morphologically, both volumes of concrete and wood, besides corresponding
to specific urban programs and dynamics, are not unrelated, respectively, to the solid wall that withstands the weather, as well as to the haystacks and the local cooperage activity.

Collective Housing


The exciting challenge of designing an isolated building from scratch with four facades is quickly faced with a set of bureaucratic and contextual constraints. Between the implantation design defined by the new urban plan in force, the barrack’s views annulment intention of the National Defense, the interference of the patrimony in the material and formal options, and the profitable and programmatic demands of the real estate developers, there was limited space for a vision that responds to the circumstances of the place.

Despite the complexity of the process, the proposal
seeks to synthesize the underlying problems, presenting itself diagrammatically simple. As a first action, the vertical circulations were placed in the north torsion area, creating a hinge element that divides the building altimetrically and typologically into two volumes. In the west volume, are the entrances to the building and a column
of Simplex apartments with three fronts. In the east volume, a commercial space on the ground floor that faces the new square and three columns of duplex apartments on half floors.

Access to the apartments is via exterior galleries that bring the light from the north into the infrastructural spaces while the bedrooms and living rooms face south, a solution that is not unrelated to Aldoar’s ascendancy. In turn, the altimetric shift enhances permeability that guarantees transversal ventilation and adds formal richness to the spaces, particularly on the corner’s last floors.

Morphologically, the proposal is a reflection of its typological organization and external circumstances, in a brutalist guise of concrete and brick that evokes the austerity of the monastery/ barrack. The north façade is cynical and belligerent, mirroring, on the one hand, the typological dichotomy, while hiding the inner truth in its walls and windows that are always the same. The south façade

is linear and transparent, extending in its clear lexicon to the west. The east façade is free and experimental, taking advantage of its unnecessary utility to bet on formal expression.

Collective Housing


The purpose is the consolidation of a protected city block in the city center by stitching the requested use – housing – with the need of solving the scale disruption of the urban void to intervene.

Schematically, it is proposed a building composed by two volumes for each street with a jagged courtyard inside the block, with a central staircase that acts as a vital piece of the project, not only by its indelible impact in the space perception, but mainly because this
is the element that defines the buildings heights, consequently, all the altimetric relations with the surrounding, namely with cornices, eaves, mansards, balconies, windows height and granite socles.

The elevation metric, the tiles color and pattern choice, the distance between windows, as well as the design of the element itself – two casement opening with a fixed top panel limited by concrete pilasters – retains the association of the dynamics and tectonic character of Porto’s surrounding buildings. The place is the inexorable circumstance that dictates the formal lexicon.

The typological distribution – 4 apartments per floor – is intentionally hostage of the urban scale memory, in a morphological corollary that results in 4 volumes of 4 roof planes each, that evoke the 4 original plots, which composes the 5th project elevation. The ground floor is physically and visually permeable, functioning as an intermediate space between public and private, the moment where commerce and housing merge together and the space where the streets connect. The apartments turn their social areas to the street while the private area take advantage of the central courtyard inmost character, assuring transversal ventilation.

Soares dos Reis Apartment



An apartment located in the 1st floor of a multi-family housing block representative of the modernist architecture of the 50’s in the city of Porto. Exaggeratedly subdivided, disproportionately dimensioned, and functionally inadequate for nowadays, this space needed an organizational readjustment. Furthermore, it was clear an overlapping of constructive layers (pavements, coverings, ceilings and window frames), that disfigured the space asking for a depuration work.

The space had two elements that seemed important to reclaim: The first element was a structural mesh of tall beams appar- ently misadjusted with the interior organization, consequence of the unusual typological distribution of the building (with apartments of larger areas in the first floor and smaller áreas in the 4 floors above). The second element that was materially and formally worthy of preservation is the pine wood floor parquet in a herringbone pattern – some parts covered with new pavements, other parts completely replaced.

In a first phase, the space was reorganized and redimensioned: We totally reconfigured the kitchen and bathrooms; general layouts were completely redefined – in the social area we created a wid-
er space where before stood four divisions, and in private area we defined a master bedromm with bathroom and two secondary ones.

In a second phase – more empirical and in result of the dem- olitions – we clarified the intervention in correlation with the beams layout, whether released and disconnected from them, evoking the pre-existing compartiments, or guided by them in their new redistribution.

Founded by Tiago Antero de Sousa


ATA is an architecture atelier from Porto, founded in 2021. It emerges from an awareness process towards an eidetic reduction of the architectural practice, in other words, an operation of synthesis of the issues considered fundamental in the designing and thinking action. The most relevant is the ability to use an analytical method as the main tool for project work, in which Place gains particular prominence. It sets a solid base to explore the relation between themes such as typology, materiality, form, space, composition, among others. This work method seeks to promote better responses, not only in regard to the needs and programs required but also in its functional and formal relationship with the city.
