Working within the constraints of an existing towerlike structure situated on a steep site overlooking the Mediterranean, architect Norman Foster created a seven-level, 6,500-square-foot modernist villa. In the living area, an 18-ton angled retractable glass wall and sun louvers “allow the inside and the outside to dissolve into one,” he says.

The street-level access opens to the pool terrace on the roof of the house. A glass staircase, at left, leads to the studio entrance below. On one of the original tower walls, a staircase with stone treads, stainless-steel railings and steel cables zigzags from the studio entrance down. Transparent glass balustrades “relate to the vistas: They’re parallel to the coast,” Foster says.
