Calculate shed costs →How to use a building calculator
Start with the size and design you are considering. Enter your measurements, select the available construction options and replace example prices with quotes from suppliers near you. Review the quantities and allowances before comparing alternatives.
What to check before buying
An online estimate is a planning aid, not a construction drawing, permit check or final shopping list. Confirm the design, foundation, structural details, waste, delivery and site costs for your location. Use our shed plans and DIY guides to continue planning.
