Haus I was the first work with Constructora Haus, and it presented two problems: how do you build a house without a client, and how do you build a house in a ravine? The answer to the first came with the solution to the second. A large platform was generated in front of the house, to achieve a stable outdoor space, capable of fulfilling several functions - parking, recreation, play. The house is located on the edge of that platform, hiding its actual size: the single floor seen from the outside is transformed into three interior floors. This structure made it possible to create a simultaneously hierarchical and fluid internal distribution, ready to be occupied by any family.
