Architecture, Building and Structure Design Casa Una Community Center by Matheus Diniz In a park in the city of Uberlandia, Brazil stands Casa Una, a community center and gathering space for park visitors and neighborhood residents. In addition to other uses, it has an open auditorium, a food hall, an office for the neighborhood association, and an exhibition space. Built with a laminated timber structure, the building uses energy-saving passive ventilation and thermal comfort techniques. Lastly, the roof is topped with three species of vegetation covered in a geometric pattern, reducing the heat gained from solar exposure and acting as a fifth facade when viewed from above.
