The geometric presence of this house design by HGT Architects gives a striking sculptural quality to a crowded residential block in central Jakarta, Indonesia. A perimeter wall envelopes the side garden to maintain privacy and provide security for the house occupants. The overall exterior composition is unique from all viewing angles against neighboring houses and enhances its corner location. Second floor windows frame interesting views of the neighboring mature trees and other neighborhood sight lines without sacrificing privacy.
A continuous interior space on the ground floor is for living, entertaining and displaying art. Load bearing walls free up the first floor from supporting columns to maximize the living area with definitive zones of activities. The open ground floor space is calming as one enters the room overlooking the side garden and an open interior patio for potted plants. By allocating open spaces on a diagonal axis, the main living space is well ventilated throughout the day. The study/play room receives full advantage of the skylight and the tall space for natural lighting as well as circulation of fresh air. Our client’s children health has made significant improvement and the family has maintained a relatively low spending cost on electricity bills since they moved in.

Energy during the construction process was saved by using FSC-certified glulam timber instead of steel to create the building’s distinctive wavy roof, while the store’s external walls use hemclad, a highly innovative insulator made from hemp, which, like all plants, absorbs CO2 from the atmosphere as it grows. An 80,000 litre water tank below ground provides water for the store’s toilets and waters the site’s green wall’, which provides natural insulation, acts as an all-natural pollution filter near the car park, and helps to encourage biodiversity. The result is a building that uses a fraction of the energy of structures of a similar size, and is still very popular with local shoppers.
The best architects can create designs which will give clients and the public things they didn’t even realise they wanted, and this is especially important when architects are given the difficult brief of creating structures in much-loved, iconic areas.
