Hi,

Have bought a place with a large plot in the green belt which means I'm restricted to PD ie eaves max 2.5m ridge max 4m

I want to build a garage / workshop and as I'd be working in there in winter I don't want it too big that I can't afford to insulate / heat it sensibly.

If / when I need further storage I'd build another garage.

I think space for 2 cars and work benches means a minimum of 10m wide (4m work area + 2m car + 1m space + 2m car + 1m space) and a saloon car is 5m plus 1m either end means 7m deep minimum.

Anyone see a problem with that ?

Large roller shutter door and a personnel door.

Whilst I was thinking of a steel frame building - they seem very easy to break into and need insulating - so I was wondering about a brick / block base to say 5 feet then a timber cladding or maybe just blockwork all the way up and render it.

I was thinking no windows just rooflights - again for security

Am I worrying too much about security - perhaps I should just alarm it ? It's surrounded by a hedge and fields.

Roof I was going to use insulated steel panels - I presume for the span I'll need a steel frame anyway to avoid trusses getting in the way.

Whilst I'd like Oak frame and tiles I can't afford it and this is for working in rather than just storage and can be placed out of sight of the house.

I'd intend to put at least one ramp in there which should be ok as most of my cars are low - I'd rather not lower the floor to then risk flooding.

Forgot to mention I've had some ballpark figures:

Steel building 10m x 7m x 2.5m eaves £10k
Installation £600
Insulation 40mm Kingspan £2K
Conc base £5k

Isnt it 2.5 metre to ridge, not eaves with planning?

I've a shed I want to put a ramp in and initially I thought I had height for this at 2.75 MTR internal, however the more I look, the less seems available under this height.

The Rules are:

Outbuildings must be single storey with a maximum eaves height of 2.5 metres and maximum overall height of 4 metres with a dual pitched roof, or
3 metres in any other case.

If the outbuilding is within 2 metres of the property boundary the whole building should not exceed 2.5 metres in height.

Hi there, i have just built one similar to what you are after.

9 meters wide 6.5 deep 3 door openings 2.5 wide.

A few things to consider, you can build it under PD as long as you build behind the front of your house and it must not cover more than 50% of your domestic curtilage IE your garden, NOTE fields / paddocks are not classed as domestic curtilage !!! Also the size you want your will need building regs.

With mind i built up to around 750mm with a wall back and sides, then full height at the front with brick, i then built a frame on it cladded it in timber and put a low pitch roof using decra tiles, not quite finished the shell but the roof is now on.

Yes this is a 2Ac curtilage.

I hadn't realised I needed B Regs for a detached garage - what are they interested in ?

Have you got any more pics of yours ?

Well i have not got building regs on mine eek but it is complicated as i built it forward of the principal elevation hoping to get away with it as i live in the middle of nowhere but got busted by the local parish councillor !! so had to apply for permission of which the parish objected to so had to go to planning committee who passed it with flying colors and they still left my PD in place thumbup

So although i got permission to build it i never applied for the building regs, and from what i believe is not mandatory but only becomes an issue when you come to sell the property in which case i will offer an insurance policy against it.

Not sure of the Regs, but i think they want to look at the footings which in my case as i had part built it (just about to put the roof on) meant core samples sent to be tested and they would want us to dig out a fes sections to prove what was done. For me this was just too much work so cracked on without it mainly as we had done it all anyways.

For some reason it will only allow me to upload 1 photo at a time so here is a side view.


This should have been completed last July but believe it or not i built this for somewhere to store the stuff from my existing garage /stables / tack room / feed room (all in one block) as i have got permission to knock that down and replace it with a 20 meter by 10 garage/ workshop with a 1st floor in it.

I am way behind now and the permission runs out on the "big one" in June ! got to pull my finger out and get it knocked down and footings out in before then.

I know you have got quotes for steel but for me i just love the look of brick and wood and it fits in very well with the surrounding area, the planning lady (who was on my side)put in her report that it could not have been built out of better materials and is why she approved the design and recommended to the committee to pass it.

Let me know if you want some more info

TBH I stumbled upon the steel ones on Ebay and couldn't believe how cheap they were but once you spec decent steel, insulation etc then add the slab they have more than doubled.

Obviously I prefer the look of brick / timber and they must be more durable although even a steel one will probably outlast me.

It's also hidden away from the house & can't been seen - for working on projects rather than parking in daily.

Do you mind giving me a rough cost ?

As i do most of the work myself and by materials when i need them it has been hard to keep a eye on the costs but here is what i have got down on paper.

Ground works was around £1,500
Brick layer around £600 Labor only
Roof trusses £1,200
Bricks,lintels, timber for the frame, cladding etc £2.200 MAX
Roof tiles and installation £3,200
3 roller doors TBA but from £2,500 - £3,000
Lights cable sockets TBA
Tile the floor TBA
Work benches and cupboards TBA
Side door TBA

Have to be to building regs if over 30m2 isn't it, even on PD?

That is my understanding, hence keeping mine under 30m2.

Thanks - I work in a similar way but haven't built a garage for 15+ yrs.

What is the implication of not bothering with B Regs ?

I can see they are essential when you sell a house but I can't see anyone cares much about a detached garage - if it's been up over a year and there isn't damp / cracking then does anyone care ?

I wouldn't.

I had council B Reg Inspector and an NHBC Inspector for my new build house - £5k utterly wasted - except for the 2 bits of essential paperwork - I could have built anything, I doubt they spent over 20mins on site in total over the course of the build.

If you know what you're doing with the building it saves a fee - about £400 at my local council.

Prior to buying another house I looked extensively into building another garage at my existing house. The area I was going to put it was very sheltered, so invariably a bit damp for half the year.

I pretty much ruled out timber because of this. Also eventually gave up on brick or block as that required proper footings as opposed to a slab which given the proximity of trees seemed logical

I always came back to a steel building. I specced up with insulated cladding. So no need to bugger about with insulation afterwards. The guy who was going to do it found some quite attractive mildly textured flat brown cladding so it even looked quite nice. I was ready to do it until another house popped up.

My existing garage is part timber construction and rot is well set in.
