Garden Building Foundations


 

That’s it! You have made the decision to have a beautiful Malvern Garden Building in your garden! But preparation is key to ensuring you can make the most of your chosen building for many years to come.


This starts with having a firm, flat, level foundation onto which the garden building can sit. Having an unsteady or uneven base can mean that your building won’t install securely or walls may warp over time, leading to leaks or damp.

There are a number of options when preparing a base for your building – here are a few of the main points to consider:

Concrete base
General advice when constructing a concrete base is to create a 10cm layer of fibre reinforced concrete. This can be applied on top of a granular sub-base should you wish, but this is not essential (a sub-base is generally not required for mature, settled gardens).

Having the foundations raised slightly above ground level encourages water to run off rather than travelling under the building. Concrete foundations are permanent, stable and non-shifting which is especially important for larger buildings, and concrete is a great low maintenance option. A concrete base is also normally the cheapest option for your garden building.

Paving slabs
For a smaller, lightweight garden building (such as a small shed), paving slabs laid on a base of sand and cement can suffice; the slabs should be evenly laid and firmly butted together. Having the slabs raised slightly above ground level will help water to run off. Paving slabs make an attractive base if you extend the paving around the building, and can be easier than concrete to remove if you want to redesign your garden. If you have left-over slabs from a previous project this can be a very economical method.

However, paving slabs alone are not recommended as a foundation option for larger buildings. For larger buildings, a concrete base is required, although paving slabs can be laid around the garden building as a decorative finish, should you wish.

Timber decking
Similar to paving slabs, a secure, level timber deck, with a weed-proof membrane between the ground and the timber is another great option for smaller garden buildings. It may be a more expensive and higher maintenance option, but provides an attractive finish, giving your garden building a beautiful setting. Timber decking can be particularly useful in hillside settings to create an even, level base, or in flood-prone areas, to raise the building up.

 

Whichever method you choose, your base should be exactly the size and shape of your garden building: you will be provided with a base plan which will fully explain the specification you should work to. The garden building should overhang the base so water drips off and doesn’t run under the building. If you are paving up to the building, the paving should be laid slightly lower than the base, again to encourage water run-off. Following the base plan will ensure these points are addressed.
