Shed Foundation Question

by Lynn

I am in the process of relocating a 12x21 storage building. I plan to have it placed on center blocks with gravel drainage underneath. How much clearance should I have under building to ground for best results?

Hi Lynn,
Thanks for your question. The main reason for lifting the shed off the ground is give it some distance from the damp ground and to allow air to circulate beneath the shed.

The timber that forms the shed floor will normally be pressure treated to resist decay. Typically the gap between the ground and the underside of the floor or timbers supporting the floor will be 100mm.

I hope this answers your question. It would be great to see some pictures of the project, underway and complete.

All the best.
