This house was developed in the spirit of its original landscape, a rare heritage site in the heart of Singapore surrounded by mature trees amidst untouched swathes of secondary forest. Based on stringent principles of sustainability, the design celebrates the undulations on a parcel of land amidst hills and giant trees, along with its birds, trees, soil and bedrock. Many mature trees were protected, and a garden nurtured to grow from seeds dropped by resident birds in preparation for an organic progression to the next generation of native trees. The characters of each space, of the light, ventilation, and of views seen from and into the living spaces were crafted around the owners’ lifestyle.
