The Technical Essentials of Healthy Housing Construction, edited by the National Housing and Living Environment Engineering Center, points out that the net height of the living room should not be less than 2.5 meters; In the "Modular Coordination Standard for Residential Buildings" edited by the Ministry of Construction, it is stipulated that the height priority size series is 2.0~3.0 meters; The Code for Residential Design stipulates that the height of ordinary residential buildings should be 2.80 meters. The indoor clear height of bedroom and living room (hall) should not be less than 2.10m, and the local clear height should not be less than 2.10m. When the space in the sloping roof is used as the bedroom and living room (hall), the indoor clear height of 1/2 area should not be less than 2 2. 10/0m. The reason why the height of residential buildings is controlled below 2.80m is "not only to control investment, but more importantly to save land, materials and resources for residential buildings" (from the provisions in the Code for Residential Design).

In addition, the Notice of the Ministry of Construction on Relevant Issues Concerning the Calculation of Building Construction Area and the Registration of House Ownership stipulates that the building height (storey height) with a building area of 2.20m or more.
