How much does it cost to build a shed?

Build the budget by category

Start with the foundation and floor. Then estimate wall framing, sheathing, siding, roof framing, roofing, doors, windows, fasteners and finishes. Add tool purchases or rentals if you do not already own what the project requires.

Size changes more than floor area

A larger footprint usually means more floor framing and roofing, but it can also change wall lengths, structural needs and the number of material sheets you need. That is why a detailed plan can make estimating easier.

Doors and windows can move the budget

A simple utility door and a basic window are very different from wide double doors, roll up doors or upgraded windows. Choose openings based on how the shed will be used.

Foundation choice matters

Site conditions and the type of foundation can have a large effect on materials and labor. Compare the common approaches in our shed foundation guide.

Leave room for waste and surprises

Real projects rarely use every board and sheet perfectly. Your estimate should leave room for offcuts, damaged material and small items that are easy to forget.

Once you have a design in mind, a plan with a material list can help turn a rough budget into a project specific estimate. See what to look for in shed plans.
