A rhythmic pattern of slots perforates the concrete screen that forms the front of this house. This filter serves a number of functions. It shades the interior, allows privacy and provides security for occupants. In addition, it projects an ever-varying arrangement of light into the house while also animating the building’s exterior with evidence of the activities inside.
The house is arranged in an E-shaped plan. Two courts between three wedge-shaped wings bring air and light deep into the interior. Around these courts, extensive vertical glazing, along with skylights, makes artificial lighting unnecessary except at night. The pure white palette used on the walls and floors further develops the sense of a house built from light and reflections as much as from solid materials.
The open plan-interior is designed to encourage family interaction and a shared family lifestyle. The wall that encloses the house and the ability to open up the glazed walls allow exterior spaces to be used as living areas. At the top of the house there is a multi-level roofscape, providing expansive views and a number of recreational spaces – parts of these are covered by grass. Amid the interior’s bright, milky coolness, a dramatic red prayer area is the symbolic heart of the house.
1 The front facade of the house is pierced by a diagonal pattern of slots. This transitional screen filters the interior and exterior light and creates an active elevation.
2 In the stairwell, the white surfaces reflect light through the house. Glimpses of the exterior are evident through the screen.
3 The roofed inner courtyard blends seamlessly with the internal spaces around it. The relationships between the spaces suggest a pattern of habitation rooted in communication and sharing.
