The area of standard rooms in general hotels is about 24.
The area of the suite is slightly larger by about 41. You need to estimate the approximate area of the common parts (walkway, pipe room, elevator room, service room, fire stairs, equipment room, etc.) on each floor.
plus the lobby and other ancillary departments (catering, shopping malls, etc.), if there are only rooms, they should be at least 1111 square meters. In that case, it's about six to seven hundred square meters.
