Tetris House derives from transforming highly pragmatic parameters into a spatially engaging concept. Several programmatic requirements (five self-contained units, parking space, exterior areas, and a potential archaeological site) have led to the creation of two volumes: L-shaped in plan and section, they are spatially interconnected to generate a variety of in-between spaces.

The building is divided into two volumes, separating the client's "private villa" with its own independent access from the smaller units that are rented out. An open staircase between the two parts provides access to the small units and the common spaces located underground. Each volume cantilevers about five meters to provide covered parking. The cantilever, which reveals its structural forces in the wall and ceiling planes, results from a combination of demands and restrictions imposed by the local government and the client.

The building site is located on a potential archaeological site with remains of a Roman settlement. To minimize expenses for archaeological excavation, the footprint has been kept as small as possible. Adhering to local height limitations while striving to achieve the maximum allowable size led to a proposal of the cantilevered design for the separate volumes.

Local materials such as larch wood are utilized throughout the design: on the exterior as facade covering and on the interior with a white tint. The sloped and shaped facade on the outside continues indoors as a built-in sideboard that transitions into a series of steps and a plinth beneath the internal stairs.
