The project is located in Tianmu Mountain scenic spot in Liyang, which is transformed from a single family villa. In addition to the traditional gathering and entertainment functions, the place will introduce nature into it. The owner who entrusts Mu Xin to design is a family who loves nature and enjoys social life. He hopes to break the indifference of urban social life and realize the interaction between social life and natural space. 

MuXin design puts forward that the communication of space is divided into man and space, space and space, space and nature. People eliminate the sense of distance in communication and turn weak relations into strong ones in different spatial communication. Strong relationships are not achieved by mandatory interaction, but by comfortable social interaction in free choice. Taking the high pitched roof on the second floor of the project as the prototype, the architect introduced the concept of "house in house". This can not only break the traditional residential layout and create rich levels, but also provide people with more "relationship" choices through the connection and complexity between nested spaces.

"House in the house" is a direct architectural logic. Coupled with the outdoor space, it naturally forms a three-tier nested structure, the interior is the exterior, and vice versa. The so-called ideal architecture can be said to be an external space similar to the interior and an internal space similar to the exterior. Architecture is not to build internal space or external space, but to build rich places between the interior and the exterior.

Emphasize the "selectivity" of space and give up the "distance limit" imposed by buildings, so that users can get their own place in the space. In the inner space of the building, there is also a 2.5-story building. The nested space within the nested space makes people think about the similarity of cities, buildings, floors and rooms. They are different manifestations of the same substance and different profiles of similar relationships. Capsule sleeping bin combined with bookcase, quiet dark gray standard guest room and impressive lazy sofa area are arranged here. 

This relatively free white space connects the natural environment outside the window and the black inner space. It has a transitional nature and a relaxed atmosphere like a semi outdoor courtyard. It can be regarded as an external space similar to the interior and an internal space similar to the exterior. The house form with complete inner space and the extended stairs strengthen the intention of "blurring indoor and outdoor".
