Inside "Barreiro House" with Aires Mateus and Architecture Hunter

June 19, 2023

The renowned Portuguese architectural practice based in Lisbon, led by architects Manuel Aires Mateus and Francisco Aires Mateus, has received several awards, notably the Valmor Prize, the Secil Prize, the FAD Awards, the Ecola Prize, the Ibero-American Architecture Biennial Awards, several Mies van der Rohe Prize selections. In 2017 he received the Pessoa Prize. 


"House in Barreiro" in addition is one of the 14 Portuguese projects nominated for the European Union Prize for Contemporary Architecture / Mies van der Rohe 2024.


The European Commission and the Fundació Mies van der Rohe have unveiled the nominees for the European Union Prize for Contemporary Architecture / Mies van der Rohe Prize 2024. This year, 362 architectural projects from 38 countries have made it to the first phase of the 18th EUmies Awards. The upcoming steps include narrowing down the selection to 40 finalists, conducting site visits, and interviewing the architects and teams involved.

These chosen projects mirror the current shifts in the European landscape, highlighting a growing emphasis on environmental, social, and economic consciousness as expressed through innovative architecture, landscaping, urban planning, and design.




“Our main focus was to preserve the building walls as we were preserving time, the concept and shape of warehouses and then shift the house entirely inwards.”  


Located in the small and picturesque city of Barreiro, with the main view of Lisbon, the project “House in Barreiro, from Aires Mateus, is a contemporary space defined by elegant minimalist architecture.

The architecture practice made most of the existing space, tailoring the interior to 21st-century life and opening the freedom to become a modern urban sanctuary. 

We joined architect Aires Mateus in a conversation as he described the structure’s simplicity, bold ambitions, and sophisticated design process. 




"The first idea of the “Casa do Barreiro”  was to preserve the walls of the two old warehouses unifying them into a single space - explains architect Aires Mateus- We designed two elevations on the top, creating two accesses that reach the roof from the ground floor, creating a kind of spiral allowing the movement of its inhabitants." 


In this project, two ambitions crossed each other: one is that the terrace on the upper part should give continuity as if two houses meet. The other was our idea of creating a structural collapse filled with water and transforming it into a swimming pool, adding a beautiful element to the house aesthetic because, from this terrace, you have a riverscape of Lisbon, which is very special. It is a terrace that did not change; the only alteration we made was introducing a protective wall to create a moment of intimacy. 




"The silhouette of the structural collapse and the undulation brings to life something I always had dreamed of", - confesses architect Aires Mateus- which was a whale."

"I always recall when in natural history museums, the giant model of a blue whale was suspended from the ceiling at the entrance to the hall.

Therefore, we connected this "whale " to the swimming pool with this sensual shape inside this space."

Afterwards, this space was defined by two stairs at either side of this central space, leading to the upper floor. The last architectural element of this project is a small house intended to fine-tune the area.  

 

When asked about the rest of the house architecture, Architect Aires Mateus explains: "We wanted to ensure that people living here would have the sensation that they could move in different ways freely. Once you arrive at the main gallery, the space is distributed from one side rooms for friends and guests, and on the other side, the space sequence for the house's parents or owners. While at the bottom are offices, bedrooms, and dressing rooms, deep down, this space brings together everything and the whole family; anyone who moves into the house is always there to participate in this space." 






" On the other two sides, create narrow gardens illuminating all areas. The idea was that the house opens to the outside through the OTIIMA, large panels and windows, without interfering with inhabitants' freedom(..) This idea of freedom and architecture is fundamental." 


"Architecture must design structures to be appropriated by people"- confirms architect Aires Mateus- "We don't even know if our buildings will have the function for which we created them; this house could become an art gallery, a museum, or a medical centre; it could be many things in its future, one grows, and it must be ready for this transformation with a certain serenity. Today, we cannot design spaces that have only one function. The architect uses the function, something other than what the architect works for."

Eduardo Souto de Moura: A Career in Architecture

By OTIIMA MMTW • July 25, 2025
Today, we celebrate the birthday of Eduardo Souto de Moura, one of Portugal's most renowned architects, whose work has had a profound influence on contemporary architecture worldwide. Famous for his minimalist and impactful designs, Souto de Moura combines tradition and modernity to create spaces that are functional and refined. A Journey in Architecture Born in Porto in 1952, Eduardo Souto de Moura studied architecture at the University of Porto, where he later became a professor. Early in his career, he was profoundly influenced by Álvaro Siza, another legendary figure in Portuguese architecture. Souto de Moura’s signature style emerged through his disciplined use of materials, a sensitive engagement with context, and an emphasis on structural clarity. In 2011, he received the Pritzker Architecture Prize, often described as the Nobel Prize of architecture, underscoring his global impact and enduring legacy. 1. Braga Stadium, Portugal Completed in 2003, Braga Stadium showcases Souto de Moura’s ability to integrate architecture with its environment. Carved into a quarry, the stadium's design respects the natural landscape, providing a unique spectator experience while highlighting his talent for harmonizing bold engineering with its surroundings.

Challenges in Modern Urban Architecture: What Architects Need to Know

By OTIIMA MMTW • July 24, 2025
Modern urban architecture faces a unique set of challenges. Cities are expanding rapidly, so architects must balance various demands, such as limited space and strict regulations, sustainability and cultural identity. Understanding these challenges is crucial for creating functional and aesthetically pleasing spaces that address the needs of today’s urban environments. Limited Space and Growing Populations  One of the most significant challenges is the limited availability of space. As more people move to urban areas, land becomes increasingly scarce and expensive. There’s a need to find creative ways to maximize every square foot, often by designing taller buildings or multi-use spaces that serve multiple purposes simultaneously. However, building upwards comes with technical considerations such as structural safety, lighting, and ventilation.

Why Originality Matters in Architecture

By OTIIMA MMTW • July 17, 2025
In a world often dominated by repetition, true originality stands out, especially in architecture. This discipline combines function, form, and emotion in the spaces where we live, work, and dream. While trends come and go, originality builds lasting value. It speaks louder than fashion, influencing culture and defining legacies. The Power of Original Thought Architecture is about shaping experiences. When architects dare to break away from convention, the results are often more than just spaces. Originality invites us to see the world differently, pushing boundaries, exploring new materials, and rethinking the relationships among light, landscape, and life. “Each new situation requires a new architecture.” — Jean Nouvel Case Study: Casa Libre, Portugal Perched on the cliffs of the Algarve coast, Casa Libre, designed by Mário Martins Atelier, expresses freedom of space, light, and thought. The architecture integrates with the surrounding landscape, rather than overpowering it, utilizing bold horizontality and deep cantilevers to create a harmonious dialogue with the Atlantic horizon. Every aspect of this project is carefully considered and intentional. The house opens entirely to the south, dissolving the boundary between interior and exterior. To achieve this radical openness, the architect relied on OTIIMA’s ultra-minimal sliding systems, which allow large glass panels to retract into the walls, revealing panoramic views without visual obstruction. Casa Libre reflects a vision of architecture that is rooted in its location and unafraid to challenge convention. The intentional use of light, material, and proportion is deeply original, not for novelty's sake, but in the pursuit of truth. This demonstrates what happens when form follows ideas rather than trends. 

The Essence of Authenticity: OTIIMA Now Directly Present in the USA

By OTIIMA MMTW • July 3, 2025
In architecture, as in life, authenticity doesn’t declare itself, it reveals itself. It’s invisible until, in the smallest gesture or the most unique detail, it shows its true nature. It is in this subtle precision that OTIIMA stands apart, embodying a design philosophy that goes beyond inspiration. OTIIMA is in the United States with the same vision, precision, and essence that have defined the brand from the start. Because, authenticity isn’t a choice, it’s where you come from. We’ve always believed that less reveals more. True minimalism demands transparency, purpose, and clear intention, an authenticity that can’t be faked or copied. In a world full of references, where it’s easy to lose touch with the source, we’ve held firmly to ours. Over the years, we’ve seen our name used, our ideas copied. But no one can replicate our DNA. And it’s this uniqueness that now brings our presence directly to the U.S. market — no intermediaries, no distortions, no imitations. There is only one OTIIMA.

Celebrating the Life and Work of Álvaro Siza Vieira

By OTIIMA MMTW • June 25, 2025
Today, June 25, 2025, Álvaro Siza Vieira celebrates his 92nd birthday. A revolutionary in the field of architecture, Siza's legacy goes beyond buildings; it shapes our perception, feelings, and experiences of space. Born in Matosinhos, Portugal, Siza has long been recognized as a master of restraint. His architecture whispers rather than shouts, respecting the landscape and honoring tradition while simultaneously expressing a deeply contemporary language. His work navigates the interplay of light and shadow, geometry and emotion, simplicity and complexity. From the Boa Nova Tea House and the Serralves Museum in Portugal to the Iberê Camargo Foundation in Brazil, his projects demonstrate a consistent commitment to timeless design and architectural integrity. Siza has received numerous awards, including the Pritzker Prize (1992), the UIA Gold Medal, and the Golden Lion for Lifetime Achievement at the Venice Architecture Biennale. Siza famously stated, "Architects do not invent anything; they transform reality." For over seven decades, he has embodied this idea, transforming cities and lives through architecture that is as subtle as it is profound.

An Architect’s Guide to Windows

By OTIIMA MMTW • June 18, 2025
When it comes to architecture, windows are never just windows. They frame views, bring in light, connect inside and out, and define the character of a space. For architects, choosing the right window system is a design decision as critical as any other. In this guide, we break down what you need to consider when specifying windows beyond aesthetics. From minimal frames to performance under pressure, this is your essential reference.

Aesthetics in Architecture: What It Is and Why It Matters

By OTIIMA MMTW • June 12, 2025
In architecture and design, aesthetics is often misunderstood as a matter of visual appeal alone. However, aesthetics is not just about what looks good; it’s about what feels right, what functions well, and what communicates meaning. It represents the intersection of form, context, and intention. Aesthetics influences every aspect of space, from how it’s perceived to how it’s used. It shapes the emotional and functional experience of architecture. When Does Aesthetics Begin? Aesthetic thinking begins from the first moment of conception, even before the first sketch. It guides decision-making throughout the design and building process. Every material chosen, every joint concealed, and every transition resolved reflects aesthetic intent. In minimalist architecture, where every element is exposed and purposeful, this becomes even more critical. When complexity is removed, aesthetics must bear the weight of both design and function. There’s no room for noise, only clarity.

"Janelar" | A Reflection by Gloria Cabral

By OTIIMA MMTW • June 6, 2025
We invited the renowned architect Gloria Cabra l to share her vision of the window, an essential architectural element. In this exclusive piece, she reflects on how openings go beyond their practical function, transforming into portals of light, connection, and new beginnings, revealing the profound poetry embedded in the act of design. Janelar “Airing out our spaces, letting the wind flow through them, creating ventanas (Spanish), making wind’s eyes— windows (English, from vindauga, Old Norse), or pores in the walls, fenêtre, finestra, fenster (French, Italian, German). I imagine this has been architecture’s desire since the occupation of caves, since the first huts, this original yearning for openings. Later, with new materials, the entry of light became possible: sometimes through flattened horns, other times stretched skins or even paper. With the discovery of glass, a new world of possibilities opened. But in Portuguese, the way we name it is different: Janela , derived from Januella, the diminutive of janua A small door, a little portal. Janela comes from the Roman god Janus, the god of beginnings and endings, transitions and decisions, the same god who opens the year in January. So, to imagine a Janela in a project is to express the beginning of something, the start of a landscape, a sky, a light, scents, or new winds. Designing a Janela is choosing what we want to see, how we want to start the day, what light we invite in, and how it enters. Windows are the instruments connecting us to what surrounds the work. And in Galicia, there’s an even lovelier word: Janelar . It turns sitting by a window and contemplating into a verb. To me, Janelar is to open a portal between inside and outside, past and future, memories, and desires.”

Biophilia: Bringing Nature into Architecture

By OTIIMA MMTW • May 29, 2025
In an era where urban density often distances us from the natural world, biophilic home design reconnects us to its source. It’s a philosophy, a return to the organic connection between people and place. Rooted in the belief that human well-being flourishes when surrounded by nature, biophilic design invites light, air, water, and greenery into the very structure of our daily lives. It softens boundaries, dissolves barriers, and opens interiors to the healing presence of the outdoors. At OTIIMA, we see minimal frames not just as tools of transparency, but as portals to presence. Our systems are about dissolving walls, not simply through glass, but through feeling. Biophilic design is based on the idea that humans thrive when connected to nature. In residential architecture, this translates into the thoughtful use of natural materials, ample daylight, fresh air circulation, and the integration of plants and outdoor views. When applied effectively, these elements improve comfort, boost mental clarity, and support overall well-being, turning a house into a healthier and more balanced living environment. Here are three houses where OTIIMA becomes the quiet conduit between architecture and nature: Touching Eden House | Wallflower Architecture + Design Singapore
