Outside the densely built centre of the city, this area of Kalamata is characterised by its many box-shaped buildings, most of which are used as warehouses. For the Kalamata Water Sport Center’s design we introduced the use of a new technology of ‘box building’ where the usual interior characteristics are far from limiting. Via the interplay between empty and solid forms, light and shadows, and successive layers of transparency, the severe geometry of the structure’s outline is transformed into a more ambiguous and playful environment.
