A family house project by a Singapore based architectural office Wallflower Architecture + Design is situated in Serangoon, in the central part of Singapore. Investor’s requirements were simple. Functionally-wise – to create as much space possible with as much integrated greenery as possible. Esthetically-wise – to use travertine as an architectural finish. The client found interest in this material during his travels in Italy. The object is divided into two parallel blocks connected by a glass enclosed bridge. This separation allows natural light to pass into the basement spaces. Thick travertine walls and large overhangs, located on the western side, are meant to prevent overheating during summers. Entrance, living spaces and bedrooms are scattered along the house, efficiently utilizing natural cross ventilation and daylight. The family house has four levels, one of which is sunken below the ground.
