Strictly speaking, office buildings can't be used by people. There are two popular evaluation criteria in the office market, one is Grade A office building and the other is 5A office building. Grade A office building is actually a popular name, and there is no fixed standard.
The large-scale office building not only means that the building itself is relatively large, but also emphasizes the extensibility and expansibility of its scale. The office building itself must have strong comprehensive support.
