Setback & Ground Coverage Calculator
Deduct the setbacks your bye-laws require from your plot and see what's actually buildable: footprint dimensions, area, and ground coverage percentage, instantly.
Basis & Assumptions
- Rectangular-plot geometry: footprint = (length − front − rear) × (width − two sides); coverage = footprint ÷ plot area.
- The first-load setback figures are examples, not assumed rules. Replace them with the local planning requirements for your plot, which can vary by plot size, road width and building height.
For quick design checks and study, not a substitute for your local Development Control Regulations, NBC provisions, or a licensed professional's judgement. Always verify against the bye-laws that apply to your site.
