The key challenge Sánchez had to face in refurbishing this 140-square-meter apartment was its long and narrow floorplan. His solution was to eschew corridors, hallways and even doors for a sequential arrangement whereby the rooms, delimited by partitions that do not reach the ceiling, run into each other. This arrangement maximizes the size of the rooms, provides uninterrupted views across the apartment by aligning the openings between spaces, and most importantly, allows daylight from the bay window on the front and the courtyard on the back to diffuse throughout the entire apartment. The glazed partition between the living room and the kitchen further facilitates the light propagation, as does the fully-glazed gallery by the courtyard, wholly reconstructed out of wood and a playful mixture of clear and translucent panels of different sizes, the latter cleverly obscuring the unappealing views out the back.
