A compact volume that leaves most of the plot untouched, respects the topography and vegetation, minimizes the excavation and permits future extensions.

A 36×36 m square plan, organized around a sky-lit atrium that improves its energetic behaviour.

A 9×9 m strucural grid, expressed on the facades, permits a great flexibility of use as well as the prefabrication of most of the building components.

An eccentric core, attached to the north facade, provides a free plan, while its position, in the center of the plot, avoids the necessity for an additional core if an extension is carried out in the future.
