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.
- Setback values themselves come from your local Development Control Regulations and vary by plot size, road width and building height — this tool never assumes them.
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.
