It is nearly 100 years since the Republic of China that this building has been standing in the Qianmen area, the center of Beijing. We reconstruction protectively this building into the secret bar hidden in the Hutong. I choose concrete to build a new arch structure and facade, because the old stone materials cannot be found. We washed the arch concrete template when the concrete set, and combined as we wish in the facade above the first floor, to make the historical picture of double-deck and multi-arch reappear through modern design and construction. The northern facade overhangs the street, I use the wood combined with the comprehensive materials to make the semi-circular box railing ,lighting inside by the circle light. From the lane during the day, we can see soft and elegant outlines and transitions of railings and terraces. At night, we can see the curved halo in the black sky.

Enter the entrance, through the small glass hallway, there is the lobby of the bar, the concrete arch from outside to inside making the image of corridor. The materials like bricks, stones, concretes and the woods corresponding to the Republic of China era. All the materials were hand made on the spot and avoid the use of modern industrial materials and disposal methods that are inconsistent with geographical and historical times in the design and construction process. This building can make people feel like they are sitting into the original moment in the history. I n the past near 100 years, this building took over by different people, the wall and the floor changed every time when the new owner came into, such like painting or paving by their individual subjective will. I remove and clean these covers and decorations, washed the building to complete what I call“taking off”process, to restore their original appearance. Compared with architects, I am the archaeologist and restorer of this project. I carefully excavated and organized the scene, and fill in the "loopholes" of space with modern materials and processes in an imperceptible way. The user's feeling has also received great attention. The bar which runs through the lobby from north to South separates the mixing area and the retail area. Seven retails are equipped with spot stage atmosphere lighting on the bar and under the bar, and can be independently switched and adjusted. At the same time, they are equipped with independent USB, guiding floor lamp and independent audio facilities, and each retail has its own space. Light and sound do not interfere with each other because of the appropriate spacing, which gives every guest a "first class" feeling. Modern equipment and appliances such as air conditioners, equipment, lamps and pipes in the lobby are hidden in the walls, ceiling and bar counter. No violation or intrusion of modern equipment and appliances will occur within the scope of the guests ‘sight. I call this control principle "Disney-like" design of "atmosphere", which can make guests enter a complete, self-consistent and closed-loop time and space experience when experiencing. Including the overall settings of products and atmosphere, surrounded by "the present", like the "theatre" of dreams.

Passing through the individual lobby, we need to go through the long corridor. through the concealed glass doors, the space suddenly opens up, and we reach the real courtyard. The quiet and private courtyard in Beijing is hidden behind the corridor. The word "QUAD HOUSE" has the meaning of a private place surrounded by surroundings and centripetal, as well as a square land surrounded by houses in east & west, south & north.

Up the stairs, you can reach the second floor of the building. Turning to the south, you will come to a large independent private room. I use the steel structure to reinforce and build the second floor again, made precise proportional control by referring to the number and size of ancient buildings. I used concealed installation of air conditioning, hydropower, rainwater and lamps, wrapped the steel structure with wood and rebuilt the roof. Turn north on the stairs on the second floor, there is the balcony. Staying on the balcony, seeing the waving roof from north and south, like the ocean push the waves toward, where people can see the child playing on the roof, in the central of the waves. People can see the ancient Qianmen tower, the present Great Hall of the People, the CBD building which will be built more than 500 meters high in future, it makes people feel a little surreal, a little unique, a little imagination and a little charming.
