Why are bases important?

Every garden building needs to be placed on a solid, flat and level base to avoid structural problems that can arise later on with temperature fluctuations (such as doors dropping). Having the right kind of base can help the building materials breath and raise the shed up off the ground away from pooling water (which can cause rotting over years).
Below we’ve made a handy guide comparing the various kinds of bases, highlighting the pros and cons of each type. Please note that it is the customer’s responsibility to consider roof overhangs and the space needed for maintenance and installation.

SHED BASE INFORMATION:

What is a base?

A shed base is foundation for your shed to be constructed upon. Just think of it the same as building a house. Before you can build a house, you need to build a solid base- this is exactly the same for a shed! 

Why do I need a base for my shed?

No matter how good our sheds are, we need a firm, level base to ensure that the building stays solid and sturdy. Without a firm, level base, it is very likely that it is not possible to assemble the structure properly- with screw holes not lining up and perhaps even doors not fitting their doorframes. These issues would have a significant impact on the structural integrity and longevity of your shed, so, to make sure that your shed is as sturdy and long-lasting as possible, make sure you have a firm and level base! 

How big should my base be?

Your base should be no smaller than the size of shed you intend to use. Ideally, it should be at least slightly larger.

When should I install my base?

Your base must be installed before the installation of your garden building.

What other things should I think about before laying a base?

  • Planning Permission

As a general rule, sheds are classified as temporary structures, and therefore will not need planning permission. However, if you live in a conservation area or your shed is particularly large, then planning permission may be needed. If you are unsure whether you will need planning permission for your shed, then it is always best to check with your local planning authority. 

  • Electricals

If you plan to add an electrical supply into your shed, then it is important to factor that into the location of your base. You will need to have a suitable electrical supply in the area where the shed is constructed. It may be best to consult a qualified electrician about the placement of your shed before building a base. 

  • Location

It is important to think about the accessibility of the area before building your shed base. If the area is sloped, it would take a large amount of work to create a level base, and therefore it is best to construct the base on a flat area of your garden if at all possible. It is also important to make sure there is clear access to your shed base, for delivery, installation and future maintenance. We require at least 8’ (2.43m) clearance for the sections to be delivered to the chosen site. It is possible for us to overcome issues in access by building in smaller sections, however this will incur an additional charge. 

Due to the possibility of a slight overhang on the roof of the shed, it is also best to not place your base too close to any walls, fences, trees or foliage. You should also consider the weather when deciding on your shed base placement. For example, do you want the sun to shine into your building, or would you like it in a more shaded area? Moreover, will your shed be in an area susceptible to the elements such as rain, wind and sun? This may have an impact on the maintenance and longevity of your shed. 

How do I lay a base for my shed?

There are multiple different methods for constructing a flat, level base. These include: 

  • Steel Base
  • Timber Base
  • Paved Base
  • Concrete Base

The most suitable materials and method for constructing your base will depend on the size and intended purpose of your shed. If you intend to use you shed primarily as a way to store garden tools or as a play area for children, then perhaps a timber base would be most suitable for you. If you are looking for a larger garden shed, and intend to use it as a home office, gym or workshop, or intend to use it to store very heavy items, then it is best for you to use a paved base or concrete base. 

Timber Base

Timber bases are suitable for: 

  • Garden Sheds
  • Small Summer Houses

Timber bearer bases are a quick, popular and cost-saving method of installing a shed base. A timber bearer base involves using treated, rot-resistant wood bearers, cut to the size needed and assembled to create a base for your building. This base will lift your shed above the damp ground, preventing rot and is therefore a good option for a garden shed or small summer house. These bases are however not suitable for larger and heavier buildings such as garden rooms. The timber bearer base must also be constructed on a level surface, and it there for may be necessary for you to level an area of your garden before constructing this base. 

Paved Base

Paved bases are suitable for:

  • Garden Sheds
  • Summer Houses
  • Log Cabins
  • Garden Rooms

Paving slabs are a great way of building a sturdy and long-lasting base for your shed, particularly if it is a larger shed or is intended to store heavy objects. To construct a paving slab base, you will need to dig down and level your surface and use builder’s sand to cover the area that you have levelled. Then carefully, starting at a corner, place down your slabs and tap gently with a mallet to press them down. Make sure to take this process slowly, using a spirit level to ensure that the slabs are level. As we’ve mentioned before, it is very important to keep the base level- so don’t rush this!

If you’d prefer not to do this process yourself, you can hire a professional to lay the paving flags for you. This way you’ll be able to sit back, relax, and know that your base will be professionally laid and level. 

Concrete Base

Concrete bases are suitable for:

  • Garden Sheds
  • Summer Houses
  • Log Cabins
  • Garden Rooms

A concrete base is a very long-lasting and sturdy option for a base. It is a pricier option, but is a much more permanent solution than, for example, a timber bearer base. It is also suitable for heavier buildings such as garden rooms, summer houses and sheds intended to store heavy items. With a concrete base, you’ll be permanently raising your garden building from the damp garden surface, and therefore ensuring longevity. 

Concrete bases require multiple steps and a certain amount of expertise. Therefore, many people decide to hire a professional to construct their concrete base. This way, you’ll have peace of mind that they concrete is being poured correctly and that your base will be level.

We offer a free site survey service should you wish to have advice on the siting of your base and building

All Garden Buildings should have a substantial base built on solid foundations.

A recycled plastic pad/grid system which is simply placed on the ground and filled with loose stone is not suitable as a base for one of our garden buildings. Whilst this is a very quick and cheap way to provide a foundation, we would only recommend using this method for light weight ‘Shed’ type structures.

We always suggest creating a Steel or Concrete Base for your garden building or room to help keep movement of the structure to a minimum enabling doors windows and sliding doors to operate seamlessly for years to come, you can decide to landscape around the building and install paths once the building is in position on its base. 

IT is possible to install garden rooms on other bases dependant on the weight and type of sub base and support i.e., decking and flag stones.
