What Is The Best Shed Base To Use?

Garden Shed Foundations

To make your garden shed look appealing and durable, you should not only consider the shed style, the flooring and materials, but also the kind of foundation you want to use. Below are some of the popular choices of garden shed foundation you can use.

Bare Earth

Even if it is the cheapest and fastest option available, placing your garden shed directly on the ground has its disadvantages.

First and foremost, moisture will seep from the ground, through into the floor and into the shed. This will result in corrosion and rot that will wear away over time.

The ground may also be soft and cause the shed to sink in places. This will put a lot of pressure on the joints of the shed, causing it to warp and split.


  • Fast
  • Cheap


  • The shed will rot and corrode


This is a simple solution for garden shed foundation, and works with small to large size garden sheds. Once you have the necessary materials, the base will only take a couple of hours, it all depends on the dimension of your shed.

All you have to do is dig out a section of ground that is slightly larger than the footprint of your shed and about three to four inches deep. After this, start adding the gravel, ensuring that you compact the gravel as much as possible. Once the base is filled, the gravel must be levelled.

You can then build your shed directly onto the gravel base.  Any voids in the gravel can be adjusted as you build the shed floor, to ensure that the structure is in full contact at all points.


  • Easy to do
  • Reasonable cost
  • Offers stable flat surface


  • Gravel can move causing the shed to move


Wooden base

Timber shed bases offer a semi-permanent solution. Typically made from 3×2 pressure treated timber, they can be easily and quickly constructed.

If your site is sloping or is uneven, a wooden base could be the best option. They consist of a frame work, which is supported by wooden or steel posts in each corner. Once built the base is placed in position and then each corner post is hammered into the ground whilst checking the levels with a spirit level.

The wooden shed base is also a good solution if the shed site is prone to flooding. The longer that the corner posts are, the higher off the ground the shed can be lifted.

If for any reason you wish to relocate the shed in the future, the base posts can be simply pulled from the ground and reused in the new location.



  • Easy to build
  • Very stable
  • Reason costs
  • Reusable


  • Can rot over time



This is probably the most expensive and time consuming base construction, however it is also the most durable and reliable.

A concrete pad is usually the best option for larger sheds due to the weight of the shed. The concrete base can be either recessed into the ground or if the site is not level, it can be raised above ground to negate the slope.

If you are not familiar with laying concrete, it may be advisable to hire professionals to complete the base for you.


  • Strong
  • Durable
  • Permanent


  • Cannot be relocated
  • Expensive
  • Difficult to construct


All of the above options for shed bases are perfectly viable. The method that you choose will usually come down to time and budget.
