Tools and materials (from the This Old House project)

• Landscape fabric, flags, landscape timbers (the frame in the project was 4x6 ground-contact pressure-treated wood), timber screws and crushed gravel.
• Tape measure, spade shovel, wheelbarrow, garden hose, impact driver, speed square, level, steel rake, screed board and a tamper. The project says you may want to rent a plate compactor.

Steps

1. Check the rules first. This Old House says to check local setbacks. It says that in most cases sheds should be at least 5 feet from the neighbors' yards and that a gravel base in the wrong spot is a lot of work to fix. See do I need a permit for a shed. Also check for buried utilities before you dig (our note, not from the source).
2. Mark the base. Use a tape measure and flags or spray paint. Over-dig by adding one foot in each direction to the shed's footprint.
3. Dig 4 to 6 inches below grade. The project used shovels and a wheelbarrow and broke up rocks and concrete with a sledgehammer.
4. Compact the soil. Use hand tampers or a rented plate compactor. Sprinkle the surface with water and keep compacting until the base is solid.
5. Lay landscape fabric. It helps prevent weeds and keeps the gravel from sinking into the soil.
6. Build the frame. Cut the timbers to match the shed. For an 8x6 shed, the project cut two timbers to 9 feet and two to 7 feet. Join them with timber screws, use a speed square to keep corners at 90 degrees, and use a level. Add handfuls of gravel under the frame wherever needed to make it level.
7. Fill with gravel. Pour it into the frame and spread it with a steel rake. Use a screed board (a 2x4 worked in the project) to level the top, filling low areas as you go.
8. Tamp and wet it. Tamp the gravel into place and spray it with the hose to dampen it for better compaction. Rake the surface to remove large stones that could affect how the shed sits.
9. Finish. After the shed goes in, This Old House suggests mulching around it to prevent splashing.

Gravel is one of several base types. See shed foundation options to compare gravel, blocks, skids and concrete.

Common questions

How deep should a gravel shed base be?

This Old House says to dig 4 to 6 inches below grade, compact the soil, then fill the frame with gravel. The page doesn't give a gravel layer thickness, so we don't either. The example project used about 1 ton of crushed gravel.

How far past the shed should the gravel extend?

This Old House says to over-dig: take the shed's footprint and add one foot in each direction. That gives room for the shed frame and gravel for extra stability and water runoff.

Do I need landscape fabric under the gravel?

The This Old House project laid landscape fabric over the compacted soil. It says the fabric helps prevent weeds and keeps the gravel from sinking into the soil over time.

Is a gravel pad enough for a large shed?

This Old House's foundation guide says gravel pads are cost-effective, DIY-friendly, drain well and suit small and medium sheds, and that they are not as permanent as concrete. It says a concrete slab is best for large sheds or sheds that house heavy equipment.

How far from the property line should the shed be?

This Old House says to check local setback rules first and that in most cases sheds should be at least 5 feet from the neighbors' yards. Your town's rule is the one that counts. See our permit and setback guide.
