Based on the firm's patented prefabricated panel system, Mrs. Fan's Plugin House was assembled by a small team in just a few hours, but has the potential to be constructed by a couple of unskilled people in as little as 24 hours using a single hex key.

Mrs. Fan's Plugin House was commissioned by a young woman who wanted to live in her parents' former courtyard house, but the existing home was very dilapidated, cramped and dark. PAO partly knocked down the old structure and inserted the new prefab to expand what was left. So, though it could serve as a standalone home, in this case it's really an extension and renovation.

The home is based on the same prefab technology used in the Plugin Tower and comprises modules with insulation, interior and exterior finish, wiring and plumbing all squeezed into one molded part. The modules attach to each other with an integrated locking system tightened by hex key.
