How much value does a double garage add to a house in the UK?
Estate agents typically put the uplift from a double garage at around 5–10% of a home's value. The smart question is how to add one for the least outlay.
As a guide, a double garage can add around 5% to 10% to the value of a UK house, depending on your location and the state of the market. Homes where off-street parking is scarce see the biggest uplift — and because a concrete sectional garage is the cheapest way to build one, it usually offers the best return on investment.
Why do buyers pay more for a double garage?
Secure parking, storage, and flexible space are the three things a double garage sells. Buyers with two cars, hobbies, bikes or tools see the value instantly, and in areas where on-street parking is contested, a double garage can be the deciding factor between two similar houses. The flexibility matters too: a double garage can serve as workshop, gym or home office space without any conversion work at all — and if a future owner does want to convert, the footprint is already there.
Does the garage material affect the value it adds?
Less than you'd think — which is exactly why material choice drives the return on investment. A brick double garage matched to the house is the premium look, but it costs the most by a distance. Block construction is cheaper than brick yet still needs rendering or cladding to look finished. Timber looks natural but needs regular treatment, which buyers notice. A concrete sectional double garage costs the least to build, installs in around a day, and needs next to no maintenance for decades — and with a brick-effect front and uPVC fascias it sits comfortably alongside the house. Buyers value the space and security; they rarely pay a premium for the wall material behind it.
Which garage gives the best return on investment?
Return on investment is the uplift minus what you spent — so the cheapest durable build wins. A concrete sectional garage removes the weeks of on-site labour that make brick and block builds expensive: the panels are cast in our Bradford factory and assembled on your base by our own teams. Every Nucrete price includes VAT, delivery and installation, and the building carries a 10-year structural guarantee — the kind of paperwork that reassures a surveyor as much as a buyer. If you're weighing up construction methods in detail, our guide to the cheapest way to build a double garage compares all four.
Is it better to add a garage or convert one?
They solve different problems. Converting an existing garage adds living space but takes away the parking and storage buyers pay for — our guide to the cost of turning a double garage into a room covers what that involves. Adding a garage does the opposite: it creates the secure space your house doesn't have. Plenty of our customers do both — convert the attached garage into a room, and put a new concrete double garage in the garden to replace what was lost. Our concrete garage prices page gives exact prices for your postcode area.
How much value does a garage add to a house in the UK?
Estimates vary with location and market conditions, but around 5–10% of the property's value is the range typically quoted for a double garage — more where off-street parking is scarce.
Does a concrete garage add as much value as a brick one?
Buyers mainly pay for secure parking and storage, not the wall material. Because a concrete sectional garage costs far less to build, it usually delivers a better return on investment than brick.
Do I need planning permission to add a double garage?
Often not — many garages fall under permitted development if they sit behind the front of the house and stay within size and height limits. Check with your local authority if you're in a conservation area or a listed building.
How quickly can a double garage be added?
On a prepared concrete base, a Nucrete double garage is typically installed in around a day. The base itself can be laid by our concrete base laying service beforehand.
