The seemingly complex geometry gives the new roof static strength, allowing the entire pool space to be covered virtually without supports. In this way, the new roof floats above the pool platform, which is designed as an exterior space. Numerous skylights in the roof, together with the ability to fully open all the facade glass surfaces, enable the guests to seamlessly pass through the interior of the building. Despite its size and the space it occupies, the new roof simply acts as a big summertime sunshade and does not usurp any of the precious exterior space.
