Text description provided by the architects. Located in Lagoa Santa, in the metropolitan region of Belo Horizonte, Casa Tangram sits on a gently sloping plot by the edge of a lake. The house is positioned at the highest point of the lot, so from the street, it appears as a discreet horizontal line, almost blending with the horizon. Walls, slopes, and the built volume itself form a visual barrier to the outside. Upon entering, one quickly realizes that the street disappears: from inside the house, only trees, the lawn, and water are visible.

The design is organized around a triangular shape, which inspires the name Tangram and unfolds in the laminated wooden roof. This roof, composed of a sequence of triangular planes, functions as a large shelter: it protects the home's intimacy from the street and opens completely towards the lake. Light enters through skylights that cut through the sky and illuminate the living areas and circulation of the upper floor. The structure is mixed, combining the lightness of the wooden roofs and balconies with the solidity of concrete slabs and walls, dialoguing with the stone walls that contain the slope of the land.

On the upper level, the intimate wing gathers a living area and five bedrooms: the master suite, two children's rooms, and two guest rooms. All open to the view, protected by the large eaves of the roof and the distance from the street. Everyday life always occurs framed by nature, never by urban traffic.

Between the precise design of the structure and the softness of the landscape, Casa Tangram seeks to be less of an object and more of a passage: a house that protects itself from the movement of the street to fully open up to the lake and vegetation, where the line of the construction extends the line of the horizon and the triangle of the roof unfolds as a gesture of welcome to nature.
