Developed in collaboration with Crosslam Brasil, a pioneering Brazilian manufacturer of engineered wood, along with construction company Abaeté, UNA barbara e valentim’s "Modular BV" system shifts away from conventional building models toward a more streamlined, precision-made assembly approach. At its core are six standardized, square modules—living room/kitchen, bedroom, studio, utility room, veranda, and garage—each measuring five by five metres. These can be arranged in different configurations depending on the program, terrain, and orientation. Precision-crafted off-site from sustainably sourced eucalyptus and assembled on location, the system significantly reduces construction time and waste while allowing for design flexibility.

Inside, the spaces are pared-back yet tactile, defined by a palette of warm, natural materials and filtered light. Walls and ceilings are lined in honey-toned eucalyptus boards, their subtle variations creating texture without ornamentation. Generous sliding glass doors allow for seamless indoor/outdoor living while framing lush views of the surrounding greenery. Furnishings are understated but soulful: rough-hewn timber furniture, woven lampshades and ceramic pendants are mixed with contemporary and vintage designs giving each space a lived-in warmth. The result is a quietly luxurious sensibility somewhere between a beach cabin and a modernist pavilion..

Bioclimatic intelligence remains the project’s true heartbeat. Broad overhangs provide gentle shade from the high noon sun, while elevated floors encourage cooling airflow beneath. Cross-ventilation is orchestrated through windows on opposite walls, augmented by roof shapes that vent rising heat. Rainwater is harvested in hidden tanks and reused, while solar panels power both electrical and hot water systems. A biodigester treats greywater and waste on site, enabling each unit to function autonomously with minimal environmental impact.
