The site for this house posed several challenges to overcome. Firstly, it is located right at the junction of two busy 4-lane roads. And in addition to that, the overhead MRT (Mass Rapid Transit) viaduct for the East-West cross-island train is located just beyond one of these roads. There is constant noise coming from cars and the passing train. The front of the site, where the main gate is located, faces almost West. To keep out heat and glare from the low angle western sun, the 2 most visible facades cannot have too many see-through openings.
