Marco Castelletti.

Castelletti came to AR's attention in the 2004 Awards for Emerging Architecture. That year his public realm project for Cesano Maderno in Italy was highly commended. He was also commended for a bathing facility on lake Segrino in Como, that the judges praised for its low impact and harmonious relationship with the landscape. This project extends the architect's interest in a building's relationship to landscape.

With internal and external pools, the building is arranged in four strips, with roofs that rise and fall. Arranged over three levels, the basement provides space for intimate treatment rooms. On the ground floor, four wet activity areas include a spa pool (above treatment rooms), children's pools, a recreation pool, and a more formal swimming pool. Three of these extend out onto a large solarium deck, while on the roof two sheltered courtyards provide additional relaxation space. An external waterslide completes the composition.
