How Much Does It Cost to Put Up/Erect a Garden Shed?

We’re not interested in the price of the shed itself. A cheap 6’ x 4’ shed from Wickes is about £150. You can keep going north from there for increasingly fancy ones!

A 2.4 metre square concrete slab, (8’x 8’) done properly but spreading the soil he digs out, over the rest of the garden rather than tipping it should take 2 men a good day. They will also have to organise the materials to arrive on time or have a “flat bed” wagon sturdy enough to take a couple of tons of “ballast”.

So labour and materials:

If you want them to put the shed up as well:

If you want power and a light and your garden is a “normal” length and he can clip the cable to the fence (i.e. not bury the whole thing 600mm underground). He will still have to find a suitable supply just inside the house, use armoured cable, fuse down for the lights etc.

Say 1.5 days for a sparks plus materials:

A Price Guide and Information Sheet on Putting up a Garden Shed

A man needs a shed! Unfortunately so does all the garden stuff, including seat cushions and possibly even the garden seats themselves plus that great umbrella thing that goes through the middle of the garden table, so get a shed that’s big enough!

You’ve always wanted a place to undertake those mucky little jobs you aren’t allowed to do on the kitchen table so now you have your chance to make a workbench with a tool rack and a vice and everything! I’m in ecstasy just thinking about it.

Don’t just go to “Wickesbase”, try the nearest timber yard as well. It’s nice to see one on display. Think about how long you want it to last, how well is it made, do you want windows and double doors, is there room for an armchair?

The first thing to think about is the base. Ideally this will be
concrete and once again must be big enough. Sheds usually go in garden corners, so think about moving it away from the fence a bit and continuing the concrete up to the fence so creating a decent area to store all that stuff that is always kept behind the shed but this time on a proper base.

If you are buying a decent one, it is worth leaving a space all the way round it for maintenance. The roof will need re-felting in ten years time and someone will need access.

If you want a workbench you will need an
electrical socket and if you have power, why not a light and a beer fridge?

Electrical power in gardens legally requires the installer to be registered with a “Competent Persons Scheme”. Now, I don’t know much about the “Worshipful Society of Garden Shed Erectors” but I suspect there’s not a man jack of them who are qualified electricians, so get the power supplied by a proper “sparks”. It can be done after the shed is up, but you might consider fitting a conduit in the concrete slab so he can eventually route his supply cable underground.

The concrete slab should be at least 75mm thick on 50mm of hardcore and should be “poured” into a rough timber mould called shuttering, which keeps it “square”.

When the shed is erected, have a look at the underside of the floor, this should be at least 50mm above the concrete, to stop rot. If it’s not, sort it out before you put lots of weight in it. Get it lifted up and put some 50mm support timbers underneath. Make sure these are no more than 350mm apart (because the floor’s probably chipboard) and go the whole way across.

So that’s it, except for carving the “Dog House” sign to hang over the door. ENJOY!
