The main interest of the project is to respond to a series of themes: the relationship between a steep topography and the new construction, clean energy production, economic maintenance aspects, a zero-energy home strategy, and specifics customer’s needs are among the set of intentions that establish a philosophy of growth and enrichment for the specific natural site.

The structure is planted in three levels ranging from street level 0 (access), level -1 (all social areas), and level -2 (bedroom and private areas). The central volume of the house is oriented towards the south, acting as a thermal mass (thermostat device) thus, allowing all adjoining areas to be naturally heated regulated.

As an economic strategy, level -2, where bedrooms are located, is a volume aligned with the natural contours lines of the site.

The overall project footprint area answers to a logic of “Plant Salvation”; a maximum number of oak trees are kept. This enables the correct distribution of green-energy roofs that will produce all energy required by the house.
