Inspired by Italo Calvino’s novel The Baron in the Trees, architect Mariana de Delás’s treehouse-like apartment is a playful experimentation of height, light, colours and material. Removing the original low gypsum (plasterboard/drywall) ceiling, de Delás added metal gangways suspended from a tubular stairway, gaining an additional 15sqm of floor space. The mezzanine houses a bedroom nook tucked away under a large skylight and a long orange plexiglass study table overlooking the open living, kitchen, and dining area, which is filled with carefully curated artwork, plants and custom cabinetry. Pops of green throughout the space bring a connection to nature, with green metal used for the gangways and staircase and green and white tiles in the bathroom imitating the lush leaves of the forest canopy.
