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

A garage is an affordable and quick way to create extra storage space for vehicles, tools, garden equipment and much more.

But how much does a typical single or double garage cost? What options are there and what’s the situation with planning permission?

Let us guide you through the options and prices.

How much a garage will cost is primarily determined by its size, foundation depth, the materials used and the type of roof you want on top of it.

On this page, we’ll look at brick-built garages (i.e. a traditional garages) as well as cheaper pre-fabricated options that have become very popular in recent years.

Brick Wall Garage Cost Guide

One of the most popular options is a brick/block garage as they blend in neatly with the house brickwork and look like part of the original construction.

You can also expect them to last as long as the house.

Single skin walls, that’s walls one brick thick, are typically used in the construction of most garages unless you want to convert the garage, or part of it, into a habitable space. If you think you might do this in the future, go for a brick and block wall that can be insulated.

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

Based on our research in 2021, a simple single brick garage, with a flat roof and just one door, the starting price is around £13,500 inc VAT. This price includes the groundwork.

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

Explore our price table below where you’ll find more examples, these were updated in April 2021 to reflect current prices being charged:

Garage Costs – Where You Can Make Savings and What May Cost More

As we are sure you can appreciate, the cost of constructing a garage varies from project to project and a garage built from bricks and blocks is the most expensive option.

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 its 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 that is structurally stronger, and you can insulate it via the cavity.

Don’t underestimate the cost of the 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 how 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 extra work 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 prefabricated garages are very quick to install, cheaper to construct, are sturdy and have a long lifespan.

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

A single garage can be erected and a roof built in about one day. A typical double garage takes around two days. This is significantly quicker than it takes to construct a brick garage.

Prefab garages and homes don’t have a good reputation in the United Kingdom but are far 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 cladding property.

However, the cost-saving of a pre-fab garage is considerable and by being creative with paint and plants, you can mask much of the concrete structure.

Also, “brick-clad” concrete garages have proven to be popular in recent years. Instead of ugly concrete panels, you get a brick-effect finish on all outside of all the walls.

We’ve looked into the cost of concrete garages and below is a guide price that includes the foundation, the garage, the roof, drainage, electrics and all the other essentials.

Single garage with pitched tiled roof£10,000 inc VAT
Double garage with pitched tiled roof£17,000 inc VAT

Timber Frame Garages

Timber garages can also be 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.

Again, this type of pre-fab garage is seen less in the UK than in mainland Europe and the US where they are very popular.

Below is a price guide for solid timber framed garage construction, this includes all the essentials such as the foundation slab, electrics, doors, window etc.

Project:Price:
Single garage with pitched tiled roof£12,000 inc VAT
Double garage with pitched tiled roof£19,000 inc VAT

Steel Garage Builds

Steel framed garages are one of the cheapest options, 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 similar to that of a concrete prefab garage but most steel garages have corrugated roofs which are rarely aesthetically pleasing.

Metal garages often suffer from condensation so aren’t suitable for everyone.

Pre-fab metal garage prices can be easily found online, you just need to add the cost of concrete floor and electrics etc.

As a general guide:

Single garage kit delivered – £4500 inc VAT.

Dig out the ground and lay concrete slab base – £2250 inc VAT.

Extras as required – insulated roof panels, guttering kit, rainwater drainage, electrics hookup and sockets, alterations to the driveway/paths etc.

Do I Need Planning Permission to Build a Garage? What About Building Regulations?

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 pre-determined 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 is constructed of mostly non-combustible materials.

Planning permission and permitted development rules are complex so we suggest you start here if you haven’t looked at them already.

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 financial return when eventually sell the property.

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

Many homeowners are converting integral garages into extra living space as this is what buyers are looking for in the current market.
