Captain's House is located on the southeast end of Huangqi Peninsula in Fujian Province. The damp and erosive nature of seaside caused the unsafeness of the existing structure and large-area water leakage during over 20 years of use. After a series of careful comparisons, architects decided to add a layer of 12cm concrete wall to the original brick masonry walls. This strategy brings potential to make a better quality of space for the existing house.
The locations and forms of openings are carefully reconsidered. The new concrete window frame sticks out from the outside wall, which prevents excessive rainwater from seeping into the window from the wall surface. The thickness is then designed into window-furniture system: window is no longer a simple opening, but serves as a medium space situating between nature and the interior space.
Vault is a structure of the third floor. It reduces the possibility of water leakage to an extreme for it barely allows any rainwater to stay. Vault connects two sides of sea with dramatically different characters: one being the serene sea whereas the other one being the noisy port. This added floor serves as a multifunctional living space: it accommodates visiting family and friends and functions perfectly as a gym or an activity room as well. Additionally, since the captain's family is Christian, this space is also intended to be a family chapel.
