Haitang Villa is a minimalist house located in Beijing, China, designed by Wen-qiang Han. The project is a three-story townhouse located in a residential area in the eastern suburbs of Beijing. The first floor and the basement are a connected space which is used to receive visitors. The second floor is for daily living, it has separate entrances and exits. The basic concept of the design is to use the changes of material and space to blur the boundary between indoor and outdoor, and the relationship among interfaces, to create an open environment rich in layers, thus to make the interior space get rid of limited decoration, and return to a natural, simple, quiet and oriental living atmosphere.
