The idea comes from a prose by Wei-lian Yeh:"Upon the undulating flows there appear twinkling lights from sailing boat. Here is a star like beacon waving its sign for our future route. Entering the door and walk into a hallway is like a trip seeking personal enlightenment. Designers embellish the door of bedroom and bathroom by a hidden door, doors merge with the wall which symbolize wave. The different direction bevel on the wall symbolize we watch the wave by different direction. It is a feeling like actually moving on top of a boat and walking down below sea level.
