Building a shed

poolpro

Hi lads. Anyone know how many bricks/blocks are needed for a garage 40 ft by 10 ft? Cheers

North West

Hi poolpro
Are you going 8' 9' high with the walls.
How many windows and what size.
Garage door size
Any other doors in shed and size?

i will do the quantities for you then, need all the above information.

I suppose you'd need to know if its hollow block or cavity wall...

Poor Uncle Tom

...and probably whether there are gables or not and if so, what pitch?

Hello again.
Checked my diary.
Block size = 440mmx215mmx100mm ( 9.88 blocks per m2 ) to build 1m2 of block you will need 10 blocks - 1x 25kg cement - 2x 25kgs sand - 12ml of plasticiser.
========================================================
Brick size = 215mm x 102mm x 65mm ( 60 bricks per m2 ) to build - 1m2 of brick you will need 60 bricks -1 x25kgs cement - 3 x 25kgs sand - 12ml plasticiser.
========================================================
No allowances are made for waste and cutting.

Thanks for replying. I'm useless at this. I'm weighing up wether I'm better to buy a steel shed or build. I want the shed to have as a games room and gym. Putting a pool table in so it has to hold heat well. 1 window maybe. No roller door needed. Just a PVC door. Will prob need a pitched roof but was told cladding or something is cheaper. Need cheapest way of blocking but without leaving me unable to heat it if that makes any sense

I'm conscious that this is poolpros thread but this may help him also. Would it be cheaper to build a double skin with cavity or to use a single skin hollow core block. Which would be most suitable.

What is the difference? I just want to get something up that can be insulated well on the inside, maybe kingspan. Block work I haven't a clue wats best. Wat are the pros and cons of each way?

400 Sq Ft.... Will it need planning permission?

Cool, just double checking that the OP was aware of it.

400Sq Ft shed built to a reasonable living standard (i know its not living, but you want it comfortable and insulated to allow the playing of pool etc) in my opinion, i would be working or an approx budget of €80-€100 per Sq. Ft.

So I'm looking at 32000-40000 roughly to build it. I have a blocker and roofer in the family. Any idea wat amount of materials I would need to buy for this size so I could price amounts to be bought??

any idea of what materials you want to use?
you cant go about quantifying and pricing until you know what you are using.

This is where I'm stuck. I want to try and do as cheap as possible. On the structure and roof. I don't mind paying to insulate and finish inside well but if the blocks and roof are too dear I won't be able. Wat would ye suggest as best way of building structure cheap. Eg blocks and roof?

best and cheap arent easy bedfellows

cheap as chips would be :

215 hollow block
72.5 insulated plasterboard (id go with EPS insulation as the different in performance is minimal while the difference in cost could be significant)
sand and cement render the outside..planning office may have input here

timber cut roof structure
single skinned galvanised roof finish
quilted fibre glass insulation to ceiling and / or continue 72.5 insulated plasterboard.

this would be the essence of a "shed" build but suitable enough to use sometimes as a hobby room

That's brilliant. At least I'm getting an idea of wat I need to be pricing now. Any ideas of quantities that would be needed of any of these for that size?

I like the idea of the 215 hollow blocks, the timber cut roof too but i'd put man made slates on roof.

2700 blocks approx.

Cheers, once I have a rough idea, at least 2700 is something I could price. Any idea on wat the wood and slates or cladding would be?

Just to point out that we dont provide a quantity surveying service.

Get a plan drawn - you have to anyhow for planning and when you decide on the materials take it to a QS

Kceire would you know a rough idea of how many 215 hollow core blocks would be needed to build a 4m by 5m garage with approx 35 degree gable.

I calculated about 480 blocks would that be near enough. I'm only trying to get a rough guide.

I make it about 600 allowing for deadwork.

Based on that being 4m by 5m needing 600 I'd hardly need 2700 for 10m by 7m would I?

You haven't decided whether you want hollow core, solid block or cavity wall construction yet.

Based on your 10 x 7m size and taking a gabled roof with pitch of 35 degrees, 2 courses or deadwork, cavity wall construction, with closer at 2.5m you will need 2,300 x 100mm concrete blocks.

The other reply I gave was specific to hollow core blocks, as requested.

Ah no worries, I'm just trying to get this up with the minimum amount of blocks so whichever why uses least is the way I need to go. Appreciate the input lads

I'm the same as you poolpro whatever is the cheapest to get up. But quality and stability are important too.

Oh big time. I have kids so has to be safe. Just if I can get away with 1 row of blocks instead of 2 and just insulate the inside then il try that

Thats why i'm considering the 215 hollow block.

I priced them on the web and the 215's are €1.43 but the ordinary block is 73 cents. I must get a price from a block layer for both options then decide.

How much are you going to be in it? insulation is a bit of a dead loss unless its preventing heat loss, if its not heated regularily, the payback will be a long time, even not considering payback, it'd seem pointless if its isnt heated? thats my view. Insulation wont keep out cold if its not heated, it just limits its loss, the upside is cold air doesnt hold as much moisture.

:eek: thats a hefty price, 10x40 sounds a bit oblong, you sure you'll have enough room to operate a pool cue?
215,2700? blocks, I calculated 600 or so

I reckon around 600 blocks, 40*10, 100 foot around is 30 or so metres, maybe 9 blocks high? that cant be more than 900 for blocks, not sure about slates but that'd depend on the pitch and if it has an apex, cheaper and a bit aged looking if you can get them second hand

It's 40 by 20. Pitched roof with cladding. Wat you think I would need in blocks for that?

40 by 20, Original post said 40x10, I prefer metres
In standard block lengths, depending on height and openings, maybe 700-800 blocks, cavities at about 1.5 per block? 1200 for blocks? you need to know the height and the size of the openings, you'll surely need a double door for that pool table.
Depends on the cladding, I think it can be similar price as tiles, its just, lighter, quicker easier to put up (I think), might work out better for a larger area.

Thanks for that. Pooltable will assemble in shed so just 1 PVC door. No windows as don't want a glare. If its less than 1000 blocks needed then this could be do-able

Basically, yes.

The best possible quality for the least amount of money, we hear you, very admirable goal.

When it's being used as a play room / garden room, and not just a shed it needs to be constructed properly taking damp proofing, insulation, cold bridging, energy usage and building regulations into account.

All this has been weighed up numerous times in the building industry and to date it has been found that the most ecconomical way of complying with all the above is by using traditional cavity wall construction.

Anything after that is just cutting corners, and will certainly not be best construction.

I'm beginning to see why the regulars are not getting involved in posting here. OP, people take time out to help and give advice here, but when you keep changing the goal posts the thread is seen as just being a timesink and posters will avoid it.

Apologies it was an error at the start with 40 by 10. So then some one said they do it in meters and I tried to convert and got it arseways. I'm not trying to waste anyone's time and I'm sorry if it looked that way lads. I do really wat to get this garage done and sorry for the confusion
