How much value does a double garage add?
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.
In short: a double garage is commonly said to add somewhere around 5% to 10% to the value of a UK house, though the figure is a guide rather than a promise and moves with location and market conditions. The uplift is largest where off-street parking is scarce, because that is where secure parking decides between two similar houses. Buyers are paying for parking, storage and flexible space rather than for the material the walls are made of, which is why the material choice mostly decides the return rather than the uplift: brick is the premium look and by some distance the dearest to build, block still needs rendering to look finished, timber needs regular treatment that buyers notice, and a concrete sectional garage costs the least while needing almost no maintenance for decades. Nucrete manufactures its double garages at its own factory in Bradford and installs most in around a day on a prepared base, with VAT, delivery and installation in the price and a 10-year structural guarantee, paperwork that reassures a surveyor as much as a buyer. Adding a garage and converting one solve opposite problems, and plenty of owners do both: convert the attached garage into a room, and replace the lost parking and storage with a new building in the garden.
