How Much Does it Cost to Build a Garage? And What Options Do You Have?

So you’re thinking about building a garage and want to get a handle on prices? Well, you’ve certainly come to the right place.

How much a garage costs will depend on its size, the foundation depth, the materials used and the type of roof you want on it.

On this page, we’ll take a detailed look at your options and prices.

Before You Proceed…

Can you answer the question below?

We are researching how much consumers think specific home improvement projects will cost them.

The poll below is optional, you can skip it if you wish but we would love your feedback!

Brick Garage Cost

Brick garages are the most popular in the United Kingdom, they blend in neatly with the existing brickwork on the property and typically last the lifetime of the house.

Single skin walls are best for most garages unless you want to convert the garage, or part of it, into a habitable room, in which case it would need to be double skinned.

The number of windows and doors will also affect the price, as will the type of roof covering; flat roofs are much cheaper than a pitched, tiled roof for example.

For a simple SINGLE brick garage, with a flat roof and just one door, the starting price is around £13,000 incVAT and including groundwork.

Make that a double garage and the price goes up considerably, especially if you want all the extras such as electric doors, the power supplied to the garage and landscaping such as extending or altering the driveway.

Explore our table below where you’ll find more examples:

Single garage with flat roof£13,000 inc VAT

Garage Cost Considerations – Savings and Extra Expenses

As we are sure you can appreciate, the cost of a garage will vary from project to project.

Here are the key points that affect the price:

The depth of the foundations and the thickness of the base slab – Concrete isn’t cheap and depending on the soil type under your proposed garage, you’re going to need a lot of it. This page has up to date prices for delivered concrete.

The type of roof you want – Flat roofs require less timberwork than a pitched roof, felt is also cheaper than tiles or slate. Flat roofs are also much quicker to construct. The downside of a flat roof is their longevity, they won’t last as long as a tiled roof, and they don’t look as appealing. This page contains a guide to garage flat roof options.

Single skin or two walls with a cavity? – Garages are usually constructed with single skin walls, but if you intend to spend a lot of time in the garage or if a garage conversion is a possibility in the future, it may be worth paying more for a double skin wall which is structurally stronger, and you can insulate it via the cavity.

Don’t underestimate the cost of the of electrics and drainage – You’ll probably want electricity in your garage which will involve creating an additional circuit from the consumer unit, the cable may need to be laid in a trench underground. How much this costs will depend on far away the garage is and what the ground is constructed from; concrete, blocks, tarmac, earth etc.  For rainwater drainage, you may be able to connect the rainwater pipes to an existing soakaway, if not, a new one may need to be constructed, see soakaway regulations and price here.

Finishing off/landscaping – For most people, a garage is useless unless the driveway is extended or altered, so it reaches the threshold of the new garage, the cost of this will depend on the type of driveway you have; concrete, block or tarmac etc. Also, consider the cost of landscaping and laying a footpath to a side door, if your garage has one. Gates, security devices, wireless door openers etc. are also extra garage costs to consider.

Concrete Sectional Garages

Concrete pre-fab garages are very quick to install, are sturdy and have a long lifespan.

The concrete sections are manufactured in a factory and delivered to site by a truck before being assembled.

A single garage can be erected and roofed in around a day, while a typical double garage takes around two days. This is significantly less time than a than it takes to construct a brick garage.

Prefab garages and homes don’t have a good reputation in the United Kingdom but are more popular in mainland Europe. The main downside of these garages is how they look. A concrete garage rarely blends in seamlessly with a brick or cladded property.

Timber Frame Garages

Timber garages are also prefabricated, and the quality of the build will vary from manufacturer to manufacturer. In general, it’s safe to assume that you’ll get what you pay for with lightweight, shiplap cladding garages having the shortest lifespan and solid timber garages lasting the longest.

Steel Garage

Steel framed garages are one of the cheapest you can buy, and they are often preferred by DIYers as they are delivered flat-pack style and are easy to erect using basic hand tools.

The price is usually less than a concrete prefab garage but most steel garages have unsightly corrugated roofs.

Can You Tell Me About Garage Regulations and Planning Permission?

Planning permission and building regulations are two different things.

To avoid the costly and time-consuming task of gaining planning permission, you may be able to construct your garage via the “permitted development” route. This means you must build the garage within a set of rules.

  • No outbuilding is located forward of the front of the house (i.e. must not be in the front garden).
  • Outbuildings and garages to be a single storey with a maximum eaves height of 2.5 metres and maximum overall height of four metres with a dual pitched roof or three metres for any other roof.
  • No verandas, balconies or raised platforms are allowed.
  • No more than half the area of land around the “original house” can be covered by additions or other buildings.

If your property is a listed building or is located on designated land, you’ll probably need full planning permission.

In most cases, you won’t need building regulations approval if your garage is less than 15 sq metres in size and contains no accommodation.

For garages between 15 sq metres and 30 sq metres, you will not typically be required to apply for building regulations approval providing that the building contains NO sleeping accommodation and is either at least one metre from any boundary or it is constructed of mostly non-combustible materials.

Is Building a Garage a Good Investment?

If you have plenty of land around your property then a garage would make a good investment and you can expect a return when you come to sell the property.

However, a garage isn’t as sought after as extra living space and building a garage onto a small plot of land might not be a good financial investment.

Many homeowners are converting integral garages into extra rooms as this is what buyers are looking for.
