The work centred on replacing the covering and enclosure of the existing heated pool and to create an adjacent spa to supplement it. The existing pool has got new facades and a new green roof, which is dotted with a series of square openings. This interplay of window holes creates a beautiful dance of light reflections in the building. In the spa area, the space is sculpted and colourful showers of light flow through the openings in the roof. This makes the building itself part of the treatment, offering the feeling of well-being created by nature when it is introduced into the building,
