The bookstore's design takes the idea of "a book falling from the sky" as the starting point of the story, and the architectural form is taken from book. Through this metaphor, we hope people can truly walk into this building to read themselves, and to complete a journey of self-discovery in a peaceful environment. The project is located at the east side of Xinglong Lake Bay Area, with a rectangle of 12m X 39m as the plane foundation, the lowest point of the roof is 3 meters in height, one corner of the building is elevated to 16 meters, and the other corner 7.5 meters, forming a roof with spiritual symbolization. When the wind lightly patting on the water, the lake surface echoes with the curving roof. The building is linearly expanded according to the site conditions, allowing itself to be connected to the open lake. The choice of a hydrophilic platform that extends out of the water and a glass window that opens on the elevation near the lake all show respect to nature. Space and the natural environment together produce a positive interaction, the building responds to the natural environment in an almost "translucent" way: grassland, trees, water, grass, and the gentle, reflecting lake surface. With neither winding corridors, nor mysterious concealment, the whole inner space gives the reader unlimited possibilities, and great physical and mental freedom. MUDA-Architects uses architectural language to propose the relationship between man and books, man and nature, and man and space. Within this building, mountains, lake and things are equivalent to people, we regain interest to each other while forgetting ourselves; within this building, people are awaken to face their true self, and to repair the degraded senses.
