This major sports building is a simple one as far as its floor plan is concerned. It is made up of two squares of identical area, one of them housing the gym hall with grandstand seating, the other containing a swimming-pool with auxiliary facilities wrapped around in an L-shape. The two blocks are both separated and connected by open and enclosed public circulation spaces. It is at roof level where the volume mutates its straightforward rectangular plan into a complex faceted copper form. Here a series of apparently random, faceted planes – all clad in copper – deconstruct the regular cube forms below, and the building suggests fragmented pieces of a broken shell.
