Brazilian architecture studio Acayaba + Rosenberg, led by Marina Acayaba and Juan Pablo Rosenberg, designed the spacious white box dwelling Casa Atlântica in São Paulo. The central space of the house was restructured with a double-height ceiling in which a large square volume hovers loose, surrounded by a sky light that bathes the interiors with a soft and homogeneous light. In the void that reverberates the white and the sound of the piano, two walls contain the staircase that reveals to the resident permanent abstract cutouts on the path between floors.

The sky light penetrates the interior by washing the walls and radically transforms white space according to the weather and seasons. The environment can take on a blueish hue on sunny days, greyish on rainy days, and orange in the late afternoon. This reveals the subtleties of the light spectrum and its intensities through the absence of colour.
