Garage Build Cost UK 2026: Sectional to Brick
Building a single garage costs £7,200–£10,800 as a concrete sectional, £9,900–£14,400 in timber frame, and £19,800–£27,900 brick-built to match the house. A brick double runs £39,600–£55,800. The spread is the walls: a sectional bolts onto a base in a day; brick is a small building project.
Garage build cost by type — 2026
Supplied and built on a standard concrete base. Single = 18m², double = 36m² — the same sizes and ranges as the garage build calculator, so you can price your own dimensions there.
| Garage type | Typical cost | Rate | Notes |
|---|---|---|---|
| Concrete sectional, single (18m²) | £7,200–£10,800 | £400–£600/m² | Prefab panels craned onto the base |
| Timber frame, single (18m²) | £9,900–£14,400 | £550–£800/m² | Workshop-friendly, easy to insulate |
| Block + render, single (18m²) | £16,200–£22,500 | £900–£1,250/m² | Masonry price without facing brick |
| Brick built, single (18m²) | £19,800–£27,900 | £1,100–£1,550/m² | Matches the house; adds most value |
| Brick built, double (36m²) | £39,600–£55,800 | £1,100–£1,550/m² | Two doors or one double span |
Q3 2026 UK price ranges, identical to the garage build calculator on this site - supplied and built, including a standard concrete base, by garage type and size. Confirm against three written quotes; ground conditions and access move real prices.
What changes the cost
| Cost factor | Typical impact | Why it matters |
|---|---|---|
| Garage type | the whole spread | Sectional £400-£600/m² against brick £1,100-£1,550/m² - the walls are the bill |
| The base and ground | included here, varies on site | A standard concrete base is in these prices; poor ground, slopes or old foundations to break out add real money |
| Doors | spec choice | An up-and-over is the baseline; insulated roller and sectional doors are the common upgrade - price them on the garage door cost page |
| Electrics | almost everyone adds them | Lighting and sockets need Part P notifiable work - agree it in the quote, not as an extra |
| Matching the house | brick premium | Facing brick to match existing masonry is the most expensive skin and the one planners prefer in conservation settings |
Garage build cost by UK region — 2026

Getting it priced properly
1. Check whether you need planning permission first
Many detached garages fall under permitted development if they stay modest in height and footprint, but the limits are specific - check your council before ordering anything.
2. Get the base and groundwork itemised
The concrete base is where surprises live. A quote that itemises excavation, sub-base and slab separately is a quote you can compare.
3. Decide sectional vs masonry on lifespan, not price alone
A sectional does the job for a fraction of brick - but brick matches the house, lasts longest and is what buyers value.

Every figure comes from the cost table above.
Garage build — frequently asked questions
From £7,200–£10,800 for a single concrete sectional garage, £9,900–£14,400 in timber frame, and £19,800–£27,900 brick-built. A brick double garage runs £39,600–£55,800. All supplied and built on a standard base.
A concrete sectional costs roughly a third of brick and goes up in a day, which makes it the value choice for storage. Brick wins where the garage sits in view of the house, needs to match it, or you want the longest life and most added value.
Often not: a detached garage can fall under permitted development within height and footprint limits, but the rules are specific about boundaries, curtilage and designated areas — confirm with your local council before committing.
These prices use 18m² for a single and 36m² for a double — the same basis as our garage build calculator, where you can price your exact dimensions, door and electrics in 30 seconds.
