Sagarana House was developed within the parametric system for prefabricated residential projects created by PELE (Personalization at Scale), a construtech spin-off of Estúdio HAA!
The project system enables infinite customization within defined parameters, resulting in a factorial number of design possibilities without altering previously tested construction solutions or compromising production scalability. In other words, the design process departs from pre-established technical standards as a way to guarantee quality and manufacturing efficiency — without that meaning more of the same, or the repetition of projects.
PELE was created as a faster, more practical alternative to the traditional architectural design process, which naturally takes time to conceive, review, and detail, and whose singularity of architectural solutions tends to produce low accuracy in budget forecasting and construction scheduling.
For Sagarana House, the brief was straightforward: two generous bedrooms, including a suite, and a large open-plan social area integrated with the kitchen. The greater challenge lay in the approach to the landscape. The site spans nearly seven hectares, with no obvious point of implantation. How do you strike a balance between the sense of expansion offered by a wide-open view and the sense of shelter and comfort that comes from being surrounded by nearby hills — an embrace that shields you from the wind and draws you closer to the land? During site visits with the clients, we ran place-reading exercises to test every viable implantation point, evaluating the advantages and drawbacks of each option against criteria including solar orientation, ease of access, construction complexity, and landscape qualities.
Once the optimal location was defined, we designed a topographic adjustment of the immediate surroundings that would generate minimal earthmoving impact while capitalizing on the site's inherent potential. As the area had previously been used as pasture, covered only by grasses, no trees needed to be removed or relocated.
The house is organized as two parallel volumes, set 2.5 meters apart and connected by a glazed corridor. The first volume houses the social areas, in direct contact with the pool. The second houses the bedroom wing — shifted toward the primary view so that the landscape is also present from the suite.
The house was built entirely in steel frame, resulting in a fast, clean construction with minimal waste, significantly reducing the environmental footprint of the build compared to Brazil's conventional construction method — reinforced concrete cast on site with masonry walls — achieving a 35 to 40 percent reduction in carbon footprint. This is due to lower consumption of heavy materials, reduced CO₂ emissions in material production, transportation savings, and less construction waste.
The choice of a prefabricated, more sustainable construction system — adopted by Estúdio HAA! — reflects an ethical commitment in the face of climate change. We understand it as a baseline requirement for acting responsibly in the built environment. Beyond the environmental benefits, advanced construction technology raises the level of workforce qualification and provides better working conditions. The system reduces physically demanding labor — such as the daily carrying of heavy materials — and allows workers to earn higher hourly wages, improving living and working conditions, particularly for those who traditionally face the harshest realities on a construction site. It is a way of fostering the reduction of social inequality within the limits of our scale of action. We believe that architectural choices extend far beyond artistic subjectivity — they can be meaningful in resisting the perpetuation of an unsustainable and inequitable status quo.
We selected only natural materials as a way of bringing comfort and subjective sensations of authenticity and permanence. Each plank of solid timber carries a unique, unrepeatable pattern — singular, beautiful, and imperfect. The natural imperfections of wood are not systematically sought out and discarded. The pursuit of aesthetic perfection in organic materials is a symptom of our time: an era in which we refuse to accept the marks of time and chase a plasticized, Instagram-ready beauty — missing, in the process, the real beauty, the possible beauty, the kind that doesn't fit within any ruler.
