Construction Costs For Brick+Metal Garage/unit

[brumster 135 1 Cars]

Wonder if anyone on the forum can give any wet-finger-in-the-air budget costs for how much it would cost to construct one of those half-block/half-metal industrial-style units (but not actually for industrial use; as a large barn/garage)? Trying to find an example on google images - this sort of thing (but nowhere near this size!)...

 

 

Contemplating a house move, but it has no garage whatsoever - however it does have land, so there's room to put something up. Thinking along the lines of staying under 4m (2.5m eaves height) to keep away from the need of planning permission. All it needs is a roller door and a normal door, a decent concrete base and that's it :-). Since space isn't a concern, I'm thinking we might as well make it 'sizeable', so ~10m square, say, or whatever is cost effective and doable around that size.

 

Anyone any vague ideas so I can decide whether it's a good idea or not?!

 

Or are they not cost effective, is a full brick construction cheaper?

I would suggest you give your sizes and a drawing to a good builders merchant who should be able to give you a quick price. I did a metal framed building of garage size using plastic cladding and that cost me a couple of grand at the end of the day!

I'd be interested to hear this.

 

I don't know what you have in mind, but it isn't going to be cheap.

 

You are going to need a fairly decent concrete base for something 10m sq. That ground work itself will be a sizeable chunk of cash.

 

Try and find a company that offers the prefab metal construction. With steel RSJ's being obsene amounts, the frame alone will be eyewatering I would have thought.

 

It really depends how realistic your thoughts are. If you are thinking several grand complete, I think you are going to be suprised.

 

If you have figured you have saved X from buying that property, and expect to get a return from using it for a specific use aswell as pleasure, then it is worth looking into further.

I would say about 15 grand for the base alone,at least.

I used to be a UPVC fitter and for a typical 4x3 conservatory base with a dwarf wall was around £2 grand

[brumster 135 1 Cars]

I suppose when you think about the price of a conservatory, I wasn't expecting this to be sub-£10k, don't worry! My plan was to take whatever it costs out of what we'd offer on the house - quite simply, no garage is a deal breaker, so I've got nothing to lose - if we can't afford to put some sort of garage up then we won't be buying, and we'll just wait for the next place to come along

[brumster 135 1 Cars]

Is a half-steel construction the wrong idea? Maybe I'm better off with a conventional brick-built garage and tiled timber roof?

[Sinbad 16]

Blocks would be your best bet with a kingspan roof i would have thought

[chipstick 382 1 Cars]

It also really depends where you are building it.

 

If you need drainage, power running to it etc etc and aren't close by any facilities then you are going to be paying a fair bit for that.

 

I think you should look at alternative construction methods - even as a comparison to see if it's worth the extra for a steel frame.

 

Or a couple of prefab concrete double garages which sell for peanuts on eBay - job done

[brumster 135 1 Cars]

No drainage needed, although I'd run some power over to it from the house. It won't be far away - just far enough to not cause planning issues of course it's not got to be pretty in my eyes, just functional and secure. Size-wise I figure if you're building something like that, and you've got the room, you may as well make use of it - so being able to get a couple of cars in it AND have lots of room for storage/tooling/engines/etc. If height wasn't an issue I also fancied a set of pillar lifts in there, but I suspect that would need a pretty high pitched roof (!) and that will probably mean planning consent, so that idea will probably end up parked.

 

Thanks guys; a few things to look into there...

[1 FAT PUG 39]

what about a larger concrete sectionable.??

[MiniGibbo 142]

As soon as a concrete slab goes down you need planning.

[brumster 135 1 Cars]

The concrete pre-fab suggestion has sent me in the direction of a number of websites, and some of them had steel constructions on there also. Although I'm in no position to comment on the quality, they range from anywhere between £7k for a double concrete sectionable to £17k-20k for a mahoosive triple steel construction. None of that includes a base or any utilities/etc so I guess if I hover my finger in the £20-30k bracket I won't be massively far off... will work on some formal quotes but first thing would be to find out if an offer several 10k's under asking price is going to float at all :-S !!

[brumster 135 1 Cars]

Ah, right - thanks for that. Ok, I'll budget for planning then - another £2k - might as well go with the height now then! In for a penny....

[MiniGibbo 142]

You want enough hieght for a ramp

[m_attt 31 1 Cars]

if you want a lift, cant you dig down to get the height. with a set of removable beams across the hole to get the car in place.

[brumster 135 1 Cars]

Sorry, I meant those 2-post lifts, not the 4 post (pillar) lifts... but to be honest, that was another level of dreaming . Garage first; if the costs and planning aren't obstructive, I'll make it big enough to accomodate a 2-post lift in the future - but it's not the end of the world if I don't fit one

[chipstick 382 1 Cars]

Depends how realistic the valuation is and what position the vendor is in.

 

I know someone who bid 307k on a 370k house recently and got it. That's a large percentage off. But then was along a stretch of road where each house differs quite a lot so values are harder to gauge and base on others.

Good old building talk its been 15 years since I was in the trade!

 

Back when I did architecture at Plymouth uni in the 90's is was £20 a meter for block work. A builder is £150 a day at the moment cash, may get one for around £120. Good old recession

 

High level its around 20k per room in a house new build, a normal garage was around 8-9k to build. A friend in work has built something similar a few years back for his live stock! He's a hobby farmer so needed somewhere for a cow etc. I'll ask again but I think it was over 20 k

 

For my extension the planning paperwork was around 300, allow 1k for the drawings but should only be £500 max really as its not a technical drawing, more shed (My drawings came in at £400) shouldn't need an architect for it and you may not need building regs as its an out building. anyway building regs paperwork starts at £120 if they are needed. Overall my planned 20k extension ended up costing me over 30k but I did have the wife and a kitchen in the mix!!!

 

 

Local planning is needed if its over a % of space increase on an existing building. Also the height has considerations, if its over X height (2m on a boundary line) it will need planning no matter what it is and within X distance from a boundard (I think 2 meters again possibly). guides can be picked up from the local planning department. Best person to have a quick chat to is building control. They inspect the build during the construction stages and I found them helpful in the planning stage for getting all the paper work in order.

 

Problem will be the land as thats the money these days, my mate who's a site manager always says the average 3 bed is around 60-70k to build, so building 3 houses you get one for free as its all profit.

 

Anyway I'll ask the hobby farmer Jason in work about his out building and get the cost and size if I remember.

 

Id look at prefab metal sheet stuff anyway (Farm out building) if its a standard size you may find one cheap as it will basically come on a lorry Brick work is x3 the cost of block, so its a lot chear to use blockwork and render it if you have to look at it from the outside.

Thanks Damo; excellent stuff. You're right on the planning/building regs (not sure which one) - ignoring the concrete base for a second, if I keep it under 2.5m at the eaves and 4m overall height, keep it more than 2m from a boundary and something like at least 5m from the main dwelling, not in front of it, and I don't take up more than 50% of the original 'curtilage', then I can just 'stick it up'. All these criteria could be met because we're thinking of putting it down in the corner of the garden. Having said that, if I need to put planning in for the concrete base then I might as well make it a little taller.

 

Another option is to put it in the corner of an adjoining field, but that will almost certainly only have agricultural planning on it so I suspect that will be a non-starter. Easier to put it in the main garden, and then re-allocated a bit of the field as an allotment (which the missus is into).

 

Ideas, ideas. Early days yet, but I didn't want to start getting everyones hopes up on the house if we couldn't find a solution to the garage problem (or afford it).

If you're planning on having electricity this is covered by part p of the building regulations and must be signed off with local building control. Use a proper sparks and they will get it sorted for you.

[daneldridge23 15]

planning is not a problem, as long as your structure is below something like 2.5m to your ridge, or flat roofs has to be under three meters, and around 30Sq ft, you do not need planning, it is classed as a temporary structure.

 

i have built numerous sheds/ garages over the years and never have needed it.

 

if you plan on having a toilet, or bedroom then you would, but im guessing its a going to be a man lab so you will be fine.

 

i built a 10 x 12 meter garage for a friend, timber framed, and the materials were something like 4 grand for the timber and concrete is roughly 65 to 85 pounds a cubic meter

 

if your a handy diy person you could save a lot in labour, but if you were to sub it all out, id allow about 10k for a top notch garadge.

 

with this in mind, why would you want a pre fab shed when you can build one tomorrow exactly how you would want it!

[damo 17 2 Cars]

ok that chap in work e-mailed me back.

 

info he sent was -

 

Yes I needed to apply for planning permission, no real concerns as it was agricultural use and

Building regs not required

£10,000 budget, mine was 7m x 12m in size

 

So hope it helps?

[kenp 3]

As soon as a concrete slab goes down you need planning.

 

Not necessarily - it comes down to permitted development rules. Depends on stuff like how far from house / boundary, roof height (as already mentioned), % of house size etc...

 

See here: http://www.planningportal.gov.uk/permission/commonprojects/outbuildings/miniguide

[MrG 3]

I'd still get planning permission even you don't officially need it, it'll help keep things square with the neighbours and when you come to sell all the forms and details will be in place.

ring the concrette plant with sizes,they will give you a quote,play them of each other a bit,but they wont move much but every penny counts.also allow a little extra money for poor ground conitions,as you may need to put stone under it,type one road stone or 6f2 cusr,or both un extremes,and well compacted in layers,if you build,id put a duct in your concrette for utilitys,much neater than running them up the outside of the building
