An apparently capricious form, which really results from objective factors: use of buildability and structural optimization. A top body supported only on 4 points, two ends being flown to compensate, and be compensated by, the interior span.
The loop as a tensile ring with which the lateral thrust of an arch cover is laid, from which the structural walls are suspended to support the loads of the floor slab. In addition, the variable edge ring wall, which forms the elliptical perimeter, provides the necessary rigidity to solve a central square of 12m side and 6m overhangs, with only 20cm of concrete slab. So, the collaboration of slabs, walls, arch cover and perimeter ring, generate a unitary structure in which each part collaborates with the others, and is essential, in the phenomenon of tension. The coexistence of structure and architecture is rarely as close as in this unique project.
The curved volume dissolves the impact of the upper floor of the house, allowing a greater interior area at the same time as a feeling of lightness and amplitude in the plot. The ellipse, far from being a whim imposed from the architectural project, plays a fundamental role in reducing the negative moments of cantilever and in the materialization of the perimeter concrete ring.
