Casa Koba is located in Gonçalves, in the south of Minas Gerais, within the Serra da Mantiqueira mountain range, known for its cold high-altitude climate. The land, located 1,450 meters above sea level, has a steep slope and covers an area of 3.7 hectares. Having already developed a project on the neighboring land, we were familiar with the local conditions, including logistical constraints, labor availability, and climate peculiarities.
From the beginning, we decided, together with the clients, to use local labor. The contractor, for example, lived in the same neighborhood as the construction site. Before starting the project, we analyzed which construction techniques were most familiar to the team, with the aim of creating something that respected the local technical vocabulary, but without replicating a design that was already known. Initially, we suggested building on the small natural plateau near the access road. However, after studying the sunlight, we found that this area would be shaded all afternoon in winter, due to a nearby mountain. We then chose another spot on the land, further away from the mountain's radius of influence and with a less steep slope. We took into account the lack of trees in the area and the visual framing of the mountains on the horizon, especially Pedra do Baú, located in São Bento do Sapucaí.
The house was organized into four functional blocks. The first block houses the family's private spaces: the master suite, the TV room, which also serves as a secondary entrance through the garage, and the children's suite. The second block was intended for the guest suites. The third block, lighter and more integrated, joins the two previous ones and concentrates the living areas: living room, indoor and outdoor kitchen, and a large front porch. The fourth block, on the lower level, includes a garage, storage room, bathroom, wine cellar and gym.
As a conceptual summary, we have a wooden plane gently resting on two clay blocks spaced apart from each other. As if the space between the private blocks itself created the social space, which, in addition to programmatic definitions, geometrically results in the intersection, that is, the encounter. A highlight of the house is the large curved wooden ceiling of the social block, which creates the sensation of being inside a shipyard, as if we were observing the hull of a suspended boat. We designed the metal trusses one by one to create this effect, in addition, of course, to fulfilling the structural function of an economic portico between the wooden pillars.
The construction system is mixed, composed of a wooden structure, steel trusses, ceramic structural masonry and reinforced concrete. The materiality of the house highlights the use of wood and ceramics, reflecting the principles of biophilia in the choice of natural materials that connect us with time and life.
