Our installers will build your shed directly onto lawn, dirt or concrete.  The shed will be secured and level on your site using H4 treated timber and plywood flooring.  No preparation is required other than providing us with a cleared site which can save you time and money. 

The shed is built on a base using 100mm x 50mm H4 treated bearers which are pegged or nailed into the ground so your shed is leveled and secure.  We then install on top of this the 18mm treated plywood floor

Sheds with no floor
We can build sheds without a floor if you have a suitable base.  We require a perfectly level deck or a purpose built concrete pad.  The base must be level for us to be able to install our sheds on.

Sloping sites
We have a surcharge for installing on a sloped site as we concrete the posts into the ground for more stability.  Talk to us if you are unsure if your site is considered sloped.
