Nestled between the river and the ocean on Bahia’s northern coastline, the Modular Bahia project reimagines the concept of a tropical retreat. Designed by Brazilian architects UNA
barbara e valentim, the house embodies a fusion of prefabricated timber construction and
bioclimatic design, deeply attuned to the local climate and landscape.
Project Name: Modular Bahia
Studio Name: UNA barbara e valentim
Sited on a peninsula, the home is arranged into three independent volumes separated by
open-air patios. This configuration accommodates varying levels of privacy and encourages
flexible coexistence between guests. A central axis links the modules, weaving together
spaces for contemplation and gathering, with views shifting between forest, river, and sea.
The architecture highlights the tactile qualities of natural materials, with wooden surfaces
lining both ceilings and walls. Expansive glass panels—shaded by deep overhangs—blur the
boundary between interior and exterior, while generous decks extend the living areas into
open verandas and terraces. These outdoor spaces provide connection and circulation
between the modules, creating a seamless flow throughout the residence.
Industrialized Timber Construction
The project employs the Modular BV system—an architectural solution developed through
collaboration between UNA barbara e valentim, Crosslam Brasil, and construction firm
Abaeté. Unlike standardized prefab models, this approach allows for tailored layouts using a diverse set of modular components. It merges rapid on-site assembly with high-quality,
sustainable design.
Modular Bahia is built using a structural system of engineered timber, featuring an
independent wooden framework and enclosures made from CLT (Cross-Laminated Timber)
panels. The use of this material ensures a cleaner, faster building process, with minimal
waste and low environmental disruption.
From its inception, the project prioritized sustainability: responsibly sourced timber, modular construction, generous eaves for solar shading, strategically placed windows for
cross-ventilation, systems for water reuse, and passive strategies for energy efficiency. Its
sloped roof design aids in thermal regulation, enhancing comfort without the need for air
conditioning.
Design Precision and Local Collaboration
The entire project was developed within a BIM (Building Information Modeling) environment, allowing for close coordination between architectural intent and industrial production. Moreover, local workers were engaged in the construction process, fostering knowledge exchange and reinforcing ties with the region’s craftsmanship.
A Forward-Looking Model for Sustainable Living
Modular Bahia reflects a shift in architectural thinking—toward ecological responsibility,
construction innovation, and contextual responsiveness. It represents a housing model that responds to today’s climatic and logistical realities, while celebrating place-based design.
As architect Fernanda Barbara notes, “The Modular system was born from a desire to bridge architectural quality and efficient execution. It reflects our belief in engineered timber as a natural evolution in sustainable construction, aligned with leading global practices.”
