Coolness and light abound in this split-level penthouse in Madrid. All access areas to the property were conceived as outdoor spaces to increase privacy and a sense of seclusion. Terraces on different levels are fed with a natural irrigation system and rain water from the roof tops; these terraces of warm earth along with the concrete structure also serve as insulators.

Internally, white walls provide the backdrop, pale wood floors and stone offer coolness under-foot. Seamlessness is created with flush, built-in cupboards and shadow gaps where level changes meet the floor. I spy: light wood Wishbone chairs, Eames DSW and Catifa chairs with their shells in white; a George Nelson clock, Panthella table lamp. The simplest metal handrails.
