in madrid, architecture studio Z4Z4 has completed a multifaceted residential property that juxtaposes different living styles and environments. named ‘casa tobogan’, the dwelling has been designed for a client who wanted a home that reflected their trips around the world, and offered a range of external living spaces. in response, the design team created two almost separate residences — a subterranean domain that spills out onto an outdoor terrace, and an elevated structure that contains plentiful sleeping accommodation. these two levels are connected via a spiral staircase that bridges an intermediate void used to channel light into the areas below.

the two environments offer a stark contrast in terms of materiality, shape and weight. the sunken level — with its natural vegetation and long concrete walls — feels embedded within the terrain, with a central courtyard conceived as a scaled-up greenhouse. the superstructure appears almost cloud-like in form, suspended in mid-air. corrugated iron curtains wrap around the three cylinders that make up the elevated building, while inside are nine rooms with a total of five bathrooms. carefully positioned apertures and terraces overlook the remainder of the property, while airy curtains and bright white walls continue the sense of lightness.
