A downward sloping site that lies some 10 meters below road level at its lowest point. 

In view of the terrain, we maximize land use vertically by building 2 levels below road level. When completed, the house would boast more than 50,000 sq ft in Gross Floor Area. Facilities include a 20-meter lap pool, an underground carpark that could accommodate 12 cars, a 4000 sq ft entertainment area at basement 1, and an indoor multipurpose hall (the size of a basketball court with an 8-meter height clearance) at basement 2. The master bedroom is outrageously large (2000 sq ft), and the remaining 5 ensuite bedrooms are at least 450 sq ft each.
