Focusing on functional simplicity, this is a large structure that sits in the centre of the flat and yet provides convenience to the family's daily activities. This is achieved by manipulating the existing space to maximise the living and storage areas, taking into account the natural light, ventilation and flow of human circulation. The 'floating' Wonder Box stretches from the kitchen to the sleeping zone, ensuring a visual continuity throughout the home. The box forms the core of the flat and hides the bomb shelter, access to air-conditioning ledge, two bathrooms and ample storage space for the family. It also houses parent and child wardrobes, TV and AV equipment cabinets as well as kitchen and dinnerware.
