The Groba House is situated in a strictly residential area. It is located in the Setor de Mansões Park Way, outside the urban preservation perimeter of the city of Brasília. It has become a place of great interest due to the bucolic landscape of the cerrado. In light of these past conditions, the architectural structure of the project is characterized by two distinct volumes that seek to engage with the typical plains of the Brasília cerrado.
Hierarchically articulated, the main block, whose geometry breaks with the conventional standards of residential typologies, invites the viewer to cross the border between the public and private domain, subtly delimited by the frontal framework that grants absolute transparency to the spaces. The invitation to transposition is further revealed in the social access, situated at a lower level in relation to the street. The articulation between the levels is promoted by a small, slightly inclined esplanade, which gradually leads the visitor to unravel the private spaces of family living. Meanwhile, the secondary block, of reduced dimensions, is simpler and houses part of the residence's intimate sector. Thus, despite the deliberate plastic distinction established between the volumes, there is a harmonious dialogue that bestows uniqueness upon the work.
The construction technique is simple. It appropriates the reinforced concrete portal as an essential device in obtaining a structural solution capable of spanning approximately six meters in the transverse direction. Six portals arranged longitudinally, every four meters and sixty, enclose the structural design of the main block. The bracing between them is ensured by longitudinal beams inverted by the slab of the first floor and by the inclined slabs of the roof. These were strategically positioned to provide an air cushion between the structure and the external metal tile enclosures that cover the entire volume and ensure excellent thermal comfort to the building. In the secondary block, a simpler structural solution is presented. It is a conventional system of reinforced concrete pillars and beams with masonry enclosures.
The intention was to conceive, through simple design approaches supported by technical rigor, a residence that would be revealed by its distinct architectural language, meeting the expectations of the owners and in harmony with the rich cerrado landscape.
