Interior Space and Exhibition Design The Eco Oasis Residential Interior by Andy Tan The creation of a light-well in the center of the house, welcomes in the natural light and air into the house which largely reduced the use of electricity. By adding green into the light-well, the space now look like an Oasis where they can enjoyed. A second level family space is created by a carefully constructed iron stairway in a beautiful off-white hue. The space above also connected to an open roof for barbecue and gathering. The house also runs on solar panel, ultimate eco-friendliness.
