This case is located in densely populated downtown Taipei, and transitional space was used as its design concept. Regarding its visual guidance, a long banded area was created to enhance its layers of visual depth to create a modern feature of simplicity. By adding mass in the central area, the designer designed a U-shaped flow to provide a visual guide from the public to the private area. The kitchen & dining area becomes a transition between public and private places to satisfy the owner’s functional need, and a moveable large sliding door was used to blur the boundary between spaces.
