Estimate Shed Materials & Construction Budgets
Ready to build extra storage space or a backyard workshop? Building a storage shed requires a solid foundation (slab or skids), wall framing studs, siding panels, roof rafters, and shingles. Use our free calculator to estimate the structural framing materials and total cost based on shed dimensions, materials, and labor choices.
Example: 10×8 ft Wood Shed on Skids with installation = 80 sq ft = approx. $2,880.00. Enter dimensions and click Calculate.
Shed Foundation Options Comparison
| Foundation Type | Est. Cost / Sq Ft | Load Capacity | Permit Difficulty |
|---|---|---|---|
| Wooden Skids (Gravel base) | $3 – $5 | Medium | Low (semi-permanent) |
| Concrete Deck Blocks | $2 – $4 | Low-Medium | Low (semi-permanent) |
| Poured Concrete Slab | $8 – $12 | Very High | High (permanent structure) |
How to Plan a Shed Build
Building a shed requires planning several components:
- Foundation: Standard sheds sit on wooden skids (4x4 pressure-treated runners) over compacted gravel, or a poured concrete slab. Wooden skids are perfect for small or medium sheds, while concrete slabs are ideal for heavy garden tractors or work benches.
- Framing Studs: Vertical wood studs (usually 2x4 lumber) spaced every 16 inches along the wall perimeter. These form the structural frame.
- Siding Panels: Large T1-11 plywood sheets or vinyl siding panels wrapped around the exterior wall studs.
- Rafters: Roof trusses running at an angle to create a pitched roof, allowing rainwater and snow to drain off.
Average Shed Construction Costs
Standard storage sheds cost between $25 and $60 per square foot to build. Prefabricated plastic or metal kits range from $600 to $2,000, while custom wooden structures built by professional carpenters average $3,000 to $7,000.
