Shed Base Sizes

Shed base guide

Asgard sheds are constructed from galvanised metal. This makes our sheds heavy, so they must be built on a level surface of tarmac, concrete or paving slabs. Below is a guide to the base size needed for each of our metal units. The importance of a shed base.

The Asgard Weight Category

Weight Category


"An Asgard shed is one of the heaviest and best quality on the market and so their self-weight and goods stored within them often mean that anchoring the base is not required for sheltered locations". John - 'The Secrets of Shed Building'

Shed bases: We recommend all our units are situated on a firm level base. Ideally, this will be concrete with a 50mm depth (2"). A patio (flag stones) and tarmac may also suitable. A depth of 50mm will allow you to anchor the unit to the ground for increased security. Exact base sizes can be found on the individual product pages.

You do not have to bolt the unit to the ground if you do not wish to.

Note: The ground anchor requires 100mm of depth.
For further information about our excellent installation service see our installation page.
