Snooker room concrete base

[Bigd81]

Morning all, my project for the coming year is to build a wooden framed snooker room in the back garden, floor plan of approx 8m X 5m, concrete base, I'm looking to do as much of it myself starting with the base, any pointers?

Under a very thin layer of topsoil the garden is heavy clay.....snooker table weighs approx 1200kgs spread over 6 or 8 legs......

TIA

Same as you'd do for a garage- dig about 300mm, whacked hardcore, sand blinding, DPM, 100mm concrete.

That size shed will be subject to building regs and (depending how big your garden is) might need planning permission.

Thanks for the advice, I don't think it'll need PP as it's a large garden and won't take up 50% of the available space, didn't realise about building regs, I presume this is something I have to take up with the local council ......

30 m² is the limit for avoiding Building Regs.
But as it is not a habitable room, the building regs will be less onerous, I assume.
E.g. less onerous on insulation,
single block walls acceptable, but may need piers, (oops! wooden frame! )
perhaps fire escape less onerous but glass in doors may still need to meet regs,
no foul water drainage required but may still need soak away for roof outfall,
electrics including supply, will still need to meet regs.

Building regs aren't a case of seeking permission, you inform building control (with a simple structure like that use a building notice), pay the fee & they check the technical details of the job- couple of site visits usually

Potential problem with a Building Notice is risk of abortive work on site if it doesn't comply. Easier to amend drawings to comply than altering work done on site !
Presumably building will be heated so heat loss will be a consideration.

Before pouring your slab stake some angle iron in the ground at various places to anchor your frame down with.

Will these have to be done by an architect?

Was planning to insulated walls and roof with rockwool? Is that acceptable?

Not necessarily. Maybe simple statements about the detail of certain aspects, e.g foundation/slab details. walls/roof design including details of insulation etc.
A builder or architectural technician would be able to assist the uninitiated for a coupe of hundred pounds, I would have thought.
A building notice as suggested by oldbutnotdead is more about inspecting details of the building during the process, rather than submitted drawings.

Include your proposals in the building regs application and await the inspectors comments or approval.
But garages/workshops/other garden buildings, although heated at times, do not need insulation. It may be more about comfort than regs.

I would contact your local authority Building Control department before you do anything else and discuss your proposed building and use giving them a rough idea on your proposed construction and see what they say about any exemptions that apply. If you make a Full Plans Submission you will obviously need drawings and an application preparing. (in that case have a word with Doppleganger about a builder or architectural technician who can do the work for £200 )
