The owner wished to have the construction completed as soon as possible before the rental contract of the company’s office at that time expired. With this condition, we gave the extended part of the office building an all-steel structure, which would be built on the original pillar grid, floor, and ceiling of the house. However, after the owner approved the design and verified that it was able to serve all the desired functions and purposes, we found that the rooms with important functions – the reception area, the product testing area, the meeting room, and the owner’s room – are all located in the front extension. Particularly, the location of the owner’s room which was close to the outdoor parking lot brought many inconveniences, such as the lack of privacy since he could be seen from the outside. From inside the office, employees would see a large concrete parking lot that was not very pleasing to see, not to mention the reflection of sunlight on the concrete and the glass walls in the south all day long, etc.
