The rectangular building might at first glance appear devoid of any furnishing or partitions but is, in fact, a fully equipped home. Apart from a pull-down metal ladder, which connects the upper level living area with the roof space, all other rooms including the lounge, dining room, study, kitchen, four bedrooms and bathrooms, storage space and sauna, are all hidden away beneath fifty hinged floor panels. These pneumatically-assisted, Yunnan-teak floorboards can be opened up and closed at will with just a tug on a pull-ring, giving endless permutations for living. When placed upright, they serve as room-dividers. When opened, a few steps downstairs leads to a completely different space. The playful design turns the usual concept of the home with fixed partitioning on its head and expands its functions well beyond the purely residential to offer a wider application for hotel or convention purposes (text from project's website).
