The functional requirement is for a temporary building for a real estate sales reception center located on Xingshan Road, Neihu District. The internal sales are not limited to a single project. Due to the constraints of building regulations, the lifespan of this project is limited to five years. Like the role of gift box packaging, it provides the first visual impression and will be constantly filled and updated with different sales project content. Within the five-year limit, the above-ground structure will be demolished in accordance with the law.
