How to build a base for a garden shed on a sloped yard?

Hammad

Hi all. Wanting to install a garden shed in this corner of our backyard but its a bit of a slope. Concreting is a very expensive option and its something we dont wish to do at this stage. 

Can I please get some tips on how to flatten this area and possibly build a base for the shed with pavers? Want it to be strong and sturdy so the pavers dont move in future. Willing to spend time and energy to do it properly but couldn't find much help online. Thanks.

Hi @Hammad,

For a garden shed on a sloped yard, it's important to create a solid and stable foundation. Most sheds, including the ones we sell, are designed to be anchored to a base like concrete or timber framing to prevent them from shifting or blowing away in strong winds. While pavers may seem like a convenient option, they aren't typically recommended for shed bases because they don't provide enough weight or stability on their own to properly anchor the shed, which could compromise the warranty.

That said, if you're set on using pavers, you could modify the approach to create a more secure base. You could first cut into the slope slightly to reduce the gradient. Then, use timber sleepers to build a mini retaining wall on the lower side of the slope. This will help you create a level platform for the shed. Once the area is levelled, instead of laying the pavers directly on the ground, which may allow them to shift over time, you can bed the pavers into a mortar base. This will lock the pavers together and create a much more solid, stable surface than loose-laid pavers.

Before laying the pavers, you'll also need to add and compact road base or crushed rock. This extra step will prevent sinking and ensure the pavers stay level. By reinforcing the pavers with mortar and properly preparing the area, you'll get a sturdier base, though it may still not be as solid as a concrete slab or timber base.

Just keep in mind that deviating from the recommended base options might void the shed's warranty, but this method should give you a strong enough platform to support the shed securely.

Please let me know if you have any questions.
