Concrete Base for large shed

mark55man

Hi - we are thinking of putting a large shed in our garden for a crafts workshop for my OH. The building will be 3.6 x 5.2 and the manufacturer has quoted £2K for digging and laying a concrete base for the shed.

This seems a touch high, but in the quote they place emphasis on the importance of a good job on the base to make the shed construction simpler and more enduring.

So grateful for any comments on what would seem reasonable in terms of labour and materials

Thanks in advance

Price it up yourself. £200 skip, £100 materials (shuttering etc), £400 concrete pour, £100 type1 base plus mini digger hire, Wacker plater hire, 2 men x a day. So you might get it a little cheaper, but not much

Thanks Dan

I have done a bit more reading - I think you are right. I might save a bit, but it would be good to make it the responsibility of the same company to do both parts of the job. I

I paid £2300 for a 4m x 7m base for a sectional concrete garage, so yours seems to be in a smiliar cost range.

2K sounds like a bargain to me. To be done properly services will need to be routed in, drainage allowed for, ground to be investigated, design produced, reinforcement sourced and built in, insulation to the floor, possibly a screed and possibly ufh, Buildingss Regulations considered...just some that come to mind.

Has all this, and more, been factored in?

Cheers for those extra replies.

Exactly the questions I am (now) going to ask!. The firm are very reputable but I was worried there was too much padding in the price. But it seems they have been fair although not cheap - which bodes well

Firm I got in about a sectional garage said the base would be £2000, that was approx 8mx4m, 4 inch slab.
There was no groundwork involved in that, as it was going down on top of the old garage base, it was just to make sure of the good base you mention.
They would just have sub contracted the job out, sure he mentioned Cemex

What building regs are needed for a shed base, given that the shed itself is under the size to require building regs itself as a structure, unless constructed of combustible material and within a short distance of a boundary, and (subject to certain conditions) could fall inside permitted development so no planning permission needed either.

Do people generally insulate the bases of sheds, or install UFH in them?

It is not being used as a shed - it is being used as a workshop. A workshop is like a mini factory in terms of mindset and considering what regs may apply. If regs apply and OP chooses to ignore them so be it, it is entirely down to them.

Most sheds are timber. These are combustible.

Workshops require heating.

Only a fool would not insulate a workshop.

It is up to OP to look into all this, and establish what may apply.
