The original house is wood framed. To minimise construction work and reveal the beauty of traditional Chinese wooden structure, we replaced the decayed roof and removed all the interior partitions. Two moveable furniture modules and one fixed module are placed under the new roof. With the moveable modules, the house can have four different layout options. According to the needs of the residents, it can shift from a three bedrooms house to a small office. The facade can be open up to connect the living space and the outdoors. The moveable modules are controlled by a smart TV. This TV system also controls lighting modes, curtains, security alarm and other home appliances. Based on the strategy of minimal intervention, we use WikiHouse system for the only new built structure on site. It serves as the kitchen and toilet. The WikiHouse is an open-source project for building houses. It is lightweight and digitally fabricated. Its faster and cleaner construction process suits the crowded and noise sensitive neighbourhood very well.
