In Einstein's curved Universe, we learn that it is circular motion that allows us to call day to day and night to night. The curvilinear path left in the skies by the passage of the sun indicates what has long been observed – it is the curve and not the right angle that prevails.
It is the free and sensual curve found in nature that has been chosen to outline the architectural object to be placed in the terrain in question. To the semicircular movement of the sun to the south, a semicircular volume is juxtaposed, emphasizing this passage and maximizing solar exposure inside the dwelling.
The volume curves and closes in on itself, underscoring the intention to become opaque and impenetrable to the northern public road. In contrast, to the south, the spaces open up and curve in response to the splendor of the sun's passage.
During the winter, the sun sweeps through the interior spaces along the entire semicircle, fulfilling its function; in the summer, the awning along the porch keeps the glass shaded.
A small natural circular amphitheater is created below the threshold level, complementing the opening of the volume to the south.
