The derelict elevator shaft in the building of OT301, owned by the Art collective EHBK in Amsterdam, is currently being transformed into a water filtration unit.
Creating a series of gardens in the sun-lit former elevator shaft, rain water is collected and run through the garden system, emulating the natural process of water filtration. The quality of water will be tested before and after the process. Ideally, it will provide a healthy source of potable water.
