Why Include Contingency Materials?
The estimate includes extra materials for cutting mistakes, damaged pieces and small adjustments. Check what you already own before buying.
- Dropped fixings: Screws and nails fall into grass, get bent, or rust
- Cutting mistakes: Timber occasionally needs replacing
- Damaged materials: Cladding boards can split during transport
- Unforeseen requirements: Extra bracing or adjustments

You've designed a shed. Here's how building it yourself compares with a ready-made shed you assemble at home.
Build it yourself
- Full control of size, timber grade & layout
- Priced from your exact cutting & materials list
- You supply the labour, tools and a weekend
- Excludes tools, delivery of materials & your time
Buy it ready-made
We may earn a commission, at no extra cost to you.
Ready-made prices are pulled from Buy Sheds Direct and may change; check the retailer for the latest price and specification. The DIY figure is an estimate of materials only and excludes tools, delivery of materials and your labour.
Sheet cutting sizes
Each panel uses one sheet, with edge-trimming allowance. This conservative layout does not reuse offcuts. Support all panel edges; allow manufacturer-specified expansion gaps.
Total timber to buy: for needed ( offcut).
