Is it expensive to build office buildings and shopping malls?

The cost of building an office building is higher than that of building a shopping mall. The matching and decoration standards of office buildings are also different from those of shopping malls. Office building standard: lobby, public walkway, elevator room and public toilet are all hardcover, with fully central air conditioning, security and fire fighting system (systems and equipment are imported brands). The facade is also a glass curtain wall and dry hanging stone. Property management companies and content are different, and office buildings pay great attention to order and quality.
