Building a shed for training?

robbieb

Hey,

Am thinking about building a shed in the back garden for training, bjj in particular. Has anyone on here done similiar and could they give advice about price, size etc?

Thanks in advance

alright there. I presume you're somewhere in Ireland. I don't know how much it would cost to lay the blocks and get a roof put on top tbh. Or perhaps you're interested in one of those steel sheds you buy as flatpack. Again, no idea.

But once that's done, you'd have to get some mats in, and the ones in typical bjj clubs are very expensive. 3m by 4m is the absolute minimum for mat space I can imagine for 3/4 people.

fightlord.com sell some mats for example

Z700 Series:
40mm x 1m x 1m = €78.00 per mat
40mm x 2m x 1m = €122.00 per mat

Z750 Series:
50mm x 1m x 1m = €85.00 per mat
50mm x 2m x 1m = €130.00 per mat

You'd need 12 by my estimate so you're talking close to 1000. You could also scout around for 2nd hand judo mats or use alternative cheaper mats. But if you're going to build a shed why skimp on mats?

You'd have to live in the middle of no where with some willing training partners to make this worth your while in my opinion (unless you have plenty of money).

Blcoks are gone way down, When I got let go a few months ago some guys were dropping them for 70c a block, I'd imagine it's only gotten lower

Unpossible

I knew of a guy who did someting like that, he even taught some classes from there. I'm not sure if it was a stand alone garage that he converted or if he built it specially.
I reckon you will have to go with the blocks and make it a proper job and have it well insulated. You don't want it getting all damp and mouldy.

I hope to do something similar if we buy a house with a garage

I'd go with 'Northingcompares' and work my budget from the mats up.

I'd say a half decent training facility is going to cost you upwards of €5k.

I know someone who has done it in their back garden in lucan. Ill try get pics when im not in work.

You ll have to sort out planning permission and keep the neighbours happy.

"Sheds" are exempted development. But is this a shed? construction costs have come way down. Used to be €850/sqm in 2007 for shell to an industrial unit. (RIAI Figures). You'll need some steel I-Beams (RSJs) for the span, I assume, what area are you looking to create, e.g. a 6m X 6m ring with 1m perimeter buffer?

he wouldnt need RSG unless he was gonna build on top of it, there is a way of getting the span using timber.

Hi Robbie,

i am a bricklayer, and i have experience in general building. do you know what size you intend the building to be, Blocks usualy cost around 1 euro to euro 1.20 per block thats to buy you then have to pay a bricky to lay them, i dont know any half decent brickie who would lay blocks for 70 cent a block on a small job such as this, they would more likely just give you a price per day or a price over all for blockwork,

you will need to dig a foundation, you will need to use a barrier on the foundation floor, and you will need to insulate the floor and walls if you want it to be a good job but these are optional,

you will need to get the roof done by a chippy or such, you will need the roof battoned and felted and then tiled, unless you want a flat roof in which case you will still need to get a chippy to or such to roof it, then you could get tarred to waterproof it, slightly cheaper option.

you would also need an electrician to wire it if you wanted lights or sockets for a radio or such, and maybe a plumber if you wanted a water feed.

after this you could fit it out with whatever you need

what size is the proposed shed to be, hieght, length, width.

considering the expense of a bricky, an electrician, a chippy, and general labour, then material costs, you might want to double that figure...;)

Have look at this site i saw one turn into a gym it looks good i am think of getting one myself

I went to this place for this exact purpose
http://www.botanicgp.com/

I had to build the foundation, and the chalet was provided & built by these guys. Very happy with the finish, and service. 5M x 5M Chalet . I also purchased Judo mats to cover the flooring.

Good idea Liam_B, what clear space size do you have internally?

"he wouldnt need RSG unless he was gonna build on top of it, there is a way of getting the span using timber." Tom Rooney

I assume, perhaps incorrectly, that the poster wants a 8m X 8m clear space, i.e. no columns, supporting partitions etc. I can't see this done in timber, not safely, not without an elaborate truss system.

This is an abridged representation of Building regulations Table A1

63 x 147 mm 3.37 m 3.24 m 2.95 m

75 x 195 mm 4.68 m 4.52 m 4.13 m
75 x 220 mm 5.11 m 4.97 m 4.64 m

As you can see 5.11m with a 220mm X 75mm on 400 cc. I have unfortunatly seen where joists have been sistered for a meter or so and bolted together mid span, the deflection in such cases is dangerous. Will you be hanging heavy bags locally on joists? Remember H&S is criminal law, you don't just get fined, you go down! If you are building a dojo for people to train in, do it right.

If you are looking for 8m X 8m that's 64 sqm and won't be exempt from planning. Otherwise your max for a "shed" is 25 sqm.

Maybe other posters who have done this could let us know what size area they found practical for training purposes, I remember once running a class (3 students) from a 6m X 6m space. Thankfully it was a prefab building, so every time someone got slammed into a wall, there was some give. Thankfully I didn't own the building, and have to deal with the leaks etc. caused by the deflection of the walls and floor.

Similarish idea - I work for myself and a few years ago I got fed up working from a nook under the stairs and started looking at those chalet buildings. In the end I decided they were a bit too pricey for what I was getting (this was the height of teh boom)

So I just bought an 18*12 shed. I can't rem how much it cost but I think it was around €1,800 fully built. Prior to build I had to lay a grid of blocks for tehm to base the shed on, but they were cheap enough and I needed one for every two or three feet of floor space. Shed as built included 4 decent sized windows (2 opening), a normal size door and chalet style roof with overhangs, window boxes, good finish on the outside, etc (basically not an eyesore or basic shed!)

The interior walls were already plastic lined but I went over the entire interior (including teh roof) and stapled another layer of plastic over it. this gives an extra layer of damp proof and catches a few inches of air to insulate. I then got teh plasterboard that has an attached aeroboard backing and drywalled the inside (more insulation), again including teh roof. After that it was a layer of damp and heat insulation on teh floor topped with laminate floorboards (which didn't work too well as teh shed wasn't totally square so it will be replaced by carpet eventually). Filled teh gaps but didn't bother skimming the plasterboard and threw on a couple of coats of paint, hung some pictures. Sparks came in and wired it and teh whole thing came in at well under 4k if memory is right.

Over time I'll replace teh windows (which are plastic) with proper double glazed ones and get a proper door on as there are drafts. But I use it all through teh winter and keep loads of electronic gear in here (computers, photocopier) and there are no damp or mould issues. Floor would be ideal for training on as it has a nice "bounce" to it. Only potential issue would be hanging a heavy bag - I wouldn't trust the beams. If you are planning it as a gym though you could build reinforcing beams into the walls before you line them and wall mount the bags. Get extra height on the walls as well, especially if you are planning on skipping.

[edit] On first reading I assumed they were building for themselves to train either solo or with one or two mates rather than running bjj classes in - if you were running classes you would need planning anyway as it would be a change of use, running a commercial business from a residential address.
