Introduction to Building 2: The first floor of Building 2 was originally the warehouse of the brake company, and the second floor is where the bicycle parking garage is located. The original iron escalator is still retained on the outer stairs. The floor slabs on the second floor of Building 2 are retained and the walls are redone. The roof is made of wood, but it has been re-insulated and waterproofed, and the old tiles have been put on. The ceiling in Building 2 is very user-friendly, with glass as the skylight. Although this walkway is very narrow, when the sun shines down from the roof, the entire park is warm and cozy. The first and second floors are accessible in all directions. People who go to work here every day can take different paths and meet different people every day. This is also a special concept of the designer - going to work is also a very happy experience.
