How Much to Build a Brick Garage in 2026? (UK)
A single brick garage typically costs £15,000–£25,000 to build in the UK in 2026, and a double from around £25,000. The price covers foundations, brickwork, a roof, a door and basic power. Size, spec, ground conditions and whether you add a pitched tiled roof or a room above all move the figure. Here is the full breakdown and how to compare quotes.
Brick garage build cost breakdown 2026
As a guide for 2026, a single brick garage (around 15–18 m²) costs £15,000–£25,000 built, a double garage (around 30–36 m²) £25,000–£40,000, and a garage with a room or office above more again. Priced by floor area that is roughly £1,200–£1,800 per m². The figure includes foundations, cavity brickwork, a roof, an up-and-over or roller door, and basic lighting and power.
What the price includes
A typical brick garage build covers groundworks and foundations, a concrete slab, cavity or single-skin brickwork, a flat or pitched roof, a garage door, and electrics for lighting and sockets. A tiled pitched roof, a personnel door, extra glazing, insulation for a habitable use, or a room in the roof all sit on top of the base figure.
What is in the price, and what is not
Quotes vary less on brickwork than on what each builder has assumed around it. The base figure above covers a working garage; the right-hand column is where two quotes for the “same” garage drift thousands apart.
Ask every builder to price the same roof type, door and electrical spec — and to say explicitly whether the foundation depth assumes normal ground. A design intended for future conversion is worth specifying now, since insulating and glazing later costs more.
What drives the price
The big levers are size, the roof type (flat is cheaper than a pitched tiled roof), ground conditions and foundation depth, access for materials and plant, and the specification — insulation, glazing, door quality and whether the garage is designed for future conversion. Sloping or poor ground, or a design that needs full planning permission, adds cost.
How to budget and compare quotes
1. Fix the size and use
Decide single or double, and whether it is purely for a car or a future workshop or room — it drives the spec.
2. Choose the roof
A flat roof is cheaper; a pitched tiled roof matches the house and lasts longer but costs more.
3. Check ground and planning
Get the ground assessed and confirm whether the size and siting need planning permission.
4. Get three like-for-like quotes
Compare on the same size, roof, door and spec so you judge value, not just headline price.
