Building a double garage - realistic costs in 2025?

ignite_me

I'm considering buying a property with a space for building a double garage but I have no clue how much it could cost. And most builders are not interested in quotes until I own the property. 

• Brick 
• Double garage door (sectional)
• Apex roof
• With concrete foundations
• About 5.5 x 5.5m in size
• Materials need to be decent but not too fancy and expensive

Similar to this picture:



What would be an appropriate ballpark figure to pay for a construction like this? I live in the North West if that matters.

Thank you 🙏

Are there any new build sites you could visit and ask the workmen on site?

i have no building experience but would say upwards of £20,000

About 4,000 external bricks = £4,000 plus labour £££???
Breeze blocks and internal bricks = £2,000 
Foundations (dig and fill) = £3,000
Concrete floor = £1,000 plus labour
Roof joists, felt, tiles, guttering = £5,000 plus labour £££???
Garage door = £1,000 plus labour to fit £££???
Electrics £1,000 plus labour £££???
Would this garage need its own fuse board ??? ----------> £££



Hopefully someone with recent experience of having one built or a builder can advise (i would be interested to know aswell as my "fag-pack" breakdown seems alot of money, even to me).

I just had a thought, would you need planning permission (councils have different regulations i think? such as if it was to take up half of the land surrounding the property you might need planning permission).
It might not need planning but might still require building control / regulations and if so you might need to factor in costs associated with site inspections, and issuing certificates etc......

Probably 40-50k.

Assuming a detached garage, one can usually build up to 30m² without needing planning permission (subject to height and location). At 5.5m by 5.5m, @ignite_me is just over the limit at 30.25m².. If PP is required, it would be worth pushing to 6m x 6m, or even a little bigger. Gives you a bit more room to scoot round inside with two cars in there.

Will you be building it on an existing parking area, or will you need to create access from the highway?

I think you're getting confused with Building Regulations.

There are far more rules to qualify for Permitted Development.

Existing parking area. There's a carport there already so I'm just looking to replace that with a brick garage.

According to this, about £40k, depending on what you want. 

The articles a year out of date, so add 5 to 10% onto the cost quoted and that'll give you an idea. I suppose.

We recently built one which was 30m2 so no need for planning permission, we paid £42k for one made with blocks and then rendered + another £2k for 2 uPVC doors and a window. Plastering, paint inside, floor and laminate flooring also included in the price. Based in North London and done about 6 months ago.

Laminate flooring in a garage?

As Doozergirl points out, 30m2 by itself isn't a criteria for permitted development.  Heights(/distance from boundary), and the percentage of original land around the house are the key ones, other than listed building/conservation area/Art 4 Direction.
