This kindergarden sits in the typical suburban landscape of Madrid periphery, an artificial irrigated landscape formed by low density suburban housing and evergreen gardens.

The kindergarden is composed by two elements: first, the construction of a collection of floors which accommodate and teach the children and, second, the construction of a roof which tempers those floors.

A COLLECTION OF FLOORS. We propose a collection of concentric floors with different colours, textures, temperatures and permeabilities. These four floors afford different spatial, ambiental and educational qualities:

• an INTERIOR STREET where all the social interaction takes place. It is paved with a Pirelli grey floor and tempered through a radiant system.
• the CLASSROOMS where teaching takes place. These spaces are paved with a red flexible sport pavement. These spaces are tempered with a radiant system with an operating temperature which is slightly over the temperature of the interior street in winter, and slightly under the interior street in summer.
• the outdoor SANDBOXES where the children play. Each classroom has its own sandbox formed by a layer of river sand over gravel.
• the outer ring is formed by a JARDIN EN MOUVEMENT which, inspired in the writings of Gilles Clement, is where kids will explore the differences between an artificial and seasonal nature.

This collection of floors builds an integral place for kids to learn. From the most intimate to the most savage, the kindergarden provides a collection of places which provide to the kids the adequate atmosphere.

A CLIMATIC ROOF. The roof provides the most adequate atmosphere to this collection of floors. It is a roof which collects, filters and stores the dissipating energy from the rain fall and sun, and redistributes it to obtain the desired atmospheric conditions.

• a rainwater harvesting roof which collects, stores and redistributes water over the jardin en movement.
• water heating solar panels located in the skylights which contribute to the radiant system which heats up the kindergarden interior spaces
• a set of four skylights which illuminate and ventilate the interior
