The horizontal and vertical lines are intertwined to form a lattice, the lattice divides the space, and the space defines the human activity. In our bar, we mainly use black and gold for our decorations. Black means darkness. It makes people feel very private and comfortable. People can do whatever they want in here. In terms of energy saving and environmental protection, we used LED energy-saving lamps throughout entire bar. From the layout, in order to maintain the air quality inside the bar, we build windows from north to south, this can make sure the natural air come through.
