A concrete foundation is certainly more permanent, but you may want to move your shed or take it with you if you’re in a rental property.
If you decide on a timber foundation, choose a treated timber so that it’s not easily damaged by rot from moisture and is not attractive to white ants. Depending on the size of your shed, start by laying 2 or more skids – this is to keep the base off the damp ground. These should be 4 x 4 or 6 x 6. If you can, use bricks or blocks underneath the skids to give your shed even greater protection from the damp ground.
Lay your joists (2 x4 or 2 x6) at intervals of approximately 25″. Using ¾” tongue and groove ply board, nail to each joist with 2 nails in each board. Do this before the floor has been exposed to the weather as it gets harder over time.
If you decide to have a concrete foundation, make sure you choose the correct location for your shed because you’ll be stuck with it! Don’t place it in a low point in the yard where water can pool and flood your shed.
You can hire a mixer and make the concrete up yourself which can be a bit of fun, or have premixed concrete delivered and poured, then all you have to do is level it.
Before you pour your concrete – do you need a ramp to access your shed? Just consider trying to lift your mower over the lip every time, or moving storage boxes and furniture in and out – just something to think about.
