Rainwater is collected from roofs and allowed to cascade from the roof via a continuous slot in the roof edge or via spouts down to pebble catchment sumps at ground level.
From these catchment sumps the water is channeled to an underground storage tank. This reservoir can, if required, supply all of the house water requirements including drinking, but generally this is used for landscape watering.
This cascading rainwater from roof to ground creates a sensual experience to heighten awareness to this tropical climate, further informing about this place.
