(1) Integral suspended ceiling is to add gypsum board or wood to the top surface to create some special shapes. Sometimes, some lighting effects are combined. However, this ceiling design will greatly reduce the floor height, and now it is basically not selected.

(2) The local ceiling is to use gypsum board and other materials to shape some parts of the top surface or the periphery of the top surface. This design is a good scheme for some roofs that need local coverage.

(3) Top surface modeling, that is, some plaster or wooden modeling patterns are directly fixed on the roof. This design, if you choose a pattern that is not very complicated and echoes the overall style of the home, can produce better results.
