This leisure centre in Amsterdam by Dutch architects VenhoevenCS was designed as a fortress covered in plants. SportPlaza Mercator is positioned at the entrance to a park in the De Baarsjes neighbourhood. The architects wanted it to fit in with its surroundings, so they added a camouflaging facade of bushy plants and flowers. Behind the planted walls, the three-storey building contains swimming pools, a sauna and fitness studios, as well as an events hall, a fast-food restaurant, a cafe and a nursery. An outdoor pool is also included at the rear.
