This free-standing single-family residence stands on a large horizontal plot. The design incorporates a composite section and use of semi-levels in an L-shaped plan for the two main building volumes. There are three courtyards, one in the front, one in the back that includes the swimming-pool, and a third one on the roof terrace next to the study.

This is a free-standing one-family residence on two levels, which forms a rectangular prism. The inner stairwell constitutes the central core of the house and culminates at a lighting pyramid. The building mass was formed by adding, removing and combining voids and plena, within the imaginary outline of a cubistic form.

The project comprises a complex of four cooperating schools with a total student population of 2000. The High School is based on a system of atria following a prominent axis that constitutes both a central passageway and an open-air space/garden. This system defines the boundaries of the private spaces of each separate school and their relationship to the larger public spaces of the general complex.

This apartment building consists of six single-floor and nine duplex apartments. The design aimed at portraying a small neighbourhood of houses-cubes, which are developped not horizontally on the ground, but vertically in space. The usual positioning of houses facing a "vague" view, typical of apartment buildings, is here broadened with actual views and correlations between the apartments themselves. This opening of the apartment building onto itself defines to some extent a specific way of life -a new quality in living together- among the tenants.
