When you walk in this container building, you will find the room is made of three container house. The designer made the white color as the dominant tone, so even the furniture such as desk, chair, bookshelf have a simple design, the whole room is highly design-driven. The modular container house is stacked up for two floors. The corridors and whole glass wall make a broad field of vision. The white stair connected two floors, so the portable building has more sense of wholeness. This site office building has a two-floor working space totally. The structure of the whole building is a steel structure which connected by bolts. This modular design is easy for assembling and disassembling; meanwhile, the bearing of whole steel structure is very good. This temporary office building does not occupy too much space but it made full use of the space. Nowadays, the urban space is increasingly precious, and we believe this prefabricated office building will inspire designers to provide a better solution for temporary houses.
