The seaside duplex building is used by the owner for vacation after work. I hope to create a simple and clean space, and use simple materials to create a reading and meditation space. The main body of the space is gray and white. A touch of blue on the wall opens up people's needs for vision. Inspiration comes from the blue brought by the sea outside the window when people open the window when they are indoors. When the Pingtan season is about to enter summer, the sea will shine blue at night, and the romance brought by blue tears will touch people's hearts.
