Shed Blocking Guide
Choose your building size and style to see the skid and block-support pattern we commonly use when setting portable sheds.
How Many Blocks Does Your Shed Need?
Select the correct width, length, and building style. The diagram will show the approximate skid layout and our typical number of block-support locations.
Building style changes the skid layout on 10-foot-wide buildings. Garages, porch buildings, and cabanas use four skids.

Important: This diagram is not a building code, engineering plan, or substitute for local requirements. It shows how 4 Seasons Portable Buildings commonly supports portable buildings adequately. Soil, slope, drainage, building design, and local rules may require different or additional site preparation and support.
What Type of Block Should Go Under a Shed?
We recommend a 4 in. × 8 in. × 16 in. solid concrete block for supporting and leveling portable buildings. Solid concrete blocks provide a strong, stable support point beneath the building’s skids.
- Place supports beneath the building’s structural skids.
- Keep the site firm, well-drained, and properly prepared.
- Adjust the number of supports when site conditions require it.
