Title: Shed on smaller base?
Post by dwellernet on Aug 4^th, 2013, 5:26pm

Hi,

I have a pre-built concrete shed base measuring exactly 10x8 feet (landlord built so I cant add to it etc)

ideally I want to put down an 8x10 wooden shed, looking around affordable ones are hard to find and the one I found is 8.3 X 10 feet, otherwise I have to go a foot smaller but ironically thats more expensive!

The suggestion I have had is use treated bearers and then put the wooden shed base on top of this, this will mean the bearers will overhang the 10 foot side by one and a half inches on each side.

Will this work or is this a poor call and will make the shed deteriorate faster?

Many thanks for any advice in advance.

Raising the shed up will probably extend it's life. You could also consider putting lengths of DPC on top of the bearers.

This should work ok, but you will have to look at how the shed needs supporting underneath, and so you will probably have to make a frame rather than just put some timber round the edge.

Thanks for the reply, the base is tongue and groove and under this thin strips of treated pine lengthways, I was looking at putting the treated bearers widthways so the sides should get the two way support on its sides, does this sound ok?

I would look to make a simple frame of 4x2 treated softwood. I would make an outer rectangle the same dimensions as the shed and then make a ladder layout with timber running across the width every 600mm max (400mm max if you are planning to put anything heavy in the shed) I would screw it all together with some 150mm screws to stop them creeping apart over time and then screw the shed down to the frame through the floor.
