The extension house is designed to connect with the old house, either tangible or intangible ways. Architectural elements such as gate, walkway, sand pond, reflecting pond and roof top are used to define negative space that harmonized with existing layout. Moreover, each room is provided more than one natural experience, for example, dining room is in between the phenomenon of pond and green wall so the sound of water and the greenery scene are created. This house is the role model of N7A “space in between” concept.
