For the annual Poolbar Festival in Feldkirch/Austria, an existing swimming pool building from the 1960s is temporarily redesigned. The aim is to achieve maximum effect with a minimum budget. Our project interprets the theme of water in a figurative sense. A pulsating wave is projected onto the exposed concrete façade of the building using laser scanners. Flexible foam furniture and backlit mesh fabrics as room dividers create a unique space for a limited time.
