Plot ratio & Building Height
Plot ratio is very important in the developer’s acquisition for a piece of land. Basically the plot ration of a site is defined as the ratio of the gross floor area of a building(s) to its site area.
Plot ratio = Gross Floor Area / Site Area
Literally speaking, the higher the plot ratio, the more gross floor area the developer is able to build up to, therefore maximizing his profit return.
Typically, the higher the plot ratio will give rise to greater building height, except for areas with special height controls are depicted on the plan. Pls see the extracted table from URA website.
Table 1: Standard GPR/Storey Height Typology for Residential Developments
| Gross Plot Ratio | Storey Height Control |
| 1.4 | 5 |
| 1.6 | 12 |
| 2.1 | 24 |
| 2.8 | 36 |
| >2.8 | >36 |
All building heights are subject to technical height controls.
