The building, renovated from an abandoned guest house, is co-designed by the house owner and designer, who expected to have the design plan preserved the original architectural structures, and avoided the excessive demolishment and reconstruction that could otherwise increase the output of wastes and input of materials. The roof overhauled with the processes of rustproof and repaint has now heightened, from the 4-meter, to the 8-meter building that contains the spaces for the café and artist performances.
