Separate the basic concepts
- Site coverage describes the area a building may occupy at ground level.
- Total construction area relates to the combined area that may be formed across storeys.
- The permitted use indicates whether residential or another type of use may be allowed.
- Storey, height, setback and parking conditions can further limit the design.
Do not treat one ratio as a value signal
A higher ratio does not automatically mean a more valuable or profitable investment. Plot shape, access, infrastructure, permissions and market need also matter.
Ask for a current written record
Planning conditions can vary by area and over time. Review a current record from the relevant authority against the exact plot details.
