A white poetic two-story building, with all the Windows eager to extend to nature. This is a renovation project that transformed a run-down building into a boutique hotel in the suburbs of Beijing. The design language of the architecture and interior is based on a quarter arc, which flows freely in the space with a rigorous attitude and increases the tension of the building by means of geometric composition. The outward extension of the building block on the facade is close to nature in a flowing posture, bringing the people in the building closer to the nature.
