This project is for a sports complex for the Madrid basketball club Estudiantes, to be used principally as a teaching venue, and was developed in collaboration with Plan 3D architects in Madrid. The site is located in a new development on Madrid's northern perimeter called Sanchinarro.

The building plan is divided into three zones: the main pavilion, the gymnasium, and the pool. Over the gymnasium and between the large volumes of the pool and pavilion is a public plaza, from which there is direct pedestrian access to the gymnasium below. The gymnasium forms the gateway to the complex and contains exercise rooms, squash courts, changing rooms, a spa, a small store, and offices.

The main pavilion is a large open space, 58 m (190ft) wide by 72 m (235ft) long, in which six basketball courts can be arranged simultaneously. Stadium seating accommodating 3,500 spectators can also be deployed for competitions. The ceiling height is 15 m (80ft), allowing for the practice of a variety of sports. A running track rings the pavilion at 4 m (13ft) above court level, and from this track there is direct access to the outdoor playing fields to the east of the pavilion. Similarly, the north facade opens to allow movement from the pavilion interior to the outdoor playing fields on that side, creating a spatial continuity between inside and outside.

The image of the building derives from the three-dimensional shape of its roofs: a collection of leaf-shaped forms suspended in the air. The undulating movement of the roofs is revealed on the principal façades and the transparency and lightness afforded by the arch structure is manifested in these facades' being entirely glazed.
