The weekend house of Ms Zhang Xin who is successful Chinese developer. Sigyeongru was built at the edge of a resort hotel developed on the mountainside in which the border is the Great Wall near Beijing. The house can be accessed by crossing a bridge over a stream after getting off the car across the stream, which was built after persuading the owner that the system will be like intercrossing daily and non-daily, reality and illusion which will be the utmost relaxation for a person who lives a busy life. And it came true. The outdoors that can be seen from the window in every room is beautiful like a landscape, but the true highlight is the scenery of the stream that can be seen down from the attic of the house and the scenery created by the silhouette of the Great Wall and the Watchtower far away. Designing with conviction and when it becomes reality, satisfaction that cannot be said in words fills up. That is the small happiness of he who is the architect.
