Located in Lantau Island, the 30 year-old residential complex Swiss Garden will be retrofitted. The complex consists of six houses (approximately 200 sq.m each) with a communal backyard, fronted by a slope filled with trees and plants. More windows will be added for cross ventilation through each house. Green features such as grey water system and green roof will be added as well. Envisioned as a green retreat, the project aims to set an example for sustainable residential design in Hong Kong by attaining BEAM Plus Gold Award whilst maximizing its property value.
