Located on a corner lot of a hilly neighborhood in the city of Semarang, Indonesia, the house opens up to its surrounding as much as it embodies comfortable living spaces in the interior of the house. The house, consisting of grey masses that have wood lined openings, is arranged geometrically based on functions. One mass is the living quarter, one mass is office and garage, and the other is the service quarter. All these masses surround a void in which an existing mango tree has been growing since tens of years ago. This void then becomes the entry point of the house.
The house has tall and wide recessed openings throughout not only to maximize physical connection to its surrounding but also to bring protected light and air into the house. This transparency creates an uninterrupted relationship between outside and inside of the house.
The house expresses the natural characteristics of its materials, raw concrete and naturally finished wood, creating integrity and honesty to the architecture of the house.
