Modular Bahia is the inaugural project of the Modular BV construction system, developed by the UNA studio, Barbara and Valentim, in partnership with Crosslam and executed by Abaeté Construtora e Incorporadora. Located on the Cocoa Coast, on the southern coast of Bahia, the complex is situated between the river and the sea, amidst a coconut grove near a tropical forest reserve.

The program is organized into three pavilions interconnected by wooden decks elevated from the ground: two independent pavilions, with bedroom, living room and kitchen, and a social pavilion, with a large kitchen, veranda and living room. The elevated placement preserves the permeability of the land and maintains the existing vegetation, giving the complex a delicate presence in the landscape.

The project used Modular BV 5.5, developed for humid tropical climates. Eaves with almost two meters of projection and upper framing between walls and roof ensure permanent cross ventilation and thermal comfort without mechanical air conditioning systems. Prefabrication in a controlled environment minimized waste on the construction site and significantly shortened the construction time, a direct response to the logistical challenges of a remote location. The system also integrates solar panels, rainwater harvesting, and wastewater treatment via a biodigester.

The Modular Bahia project was presented at the Monsoon Architecture Festival 2025 in India, promoted by the Indian Institute of Architects (IIA), and also received an honorable mention at DNA Paris 2025, consolidating the project as an international benchmark in industrialized sustainable construction.
