How Much it Costs to Build a Garage

When you’re thinking about building a garage for your property, the first thing you will need to know is how much to set aside for your budget. Not many people know that this extends beyond the individual costs of materials and labour, so how much does it cost to build a garage in the UK, really? 

Below, we’ve set out a guide on what you should think about before building your garage, the different types and materials available, and other considerations that might affect the price of your planned project. Read on to find out more, or get in touch today if you’d like a quote on one of our easy-to-build garage kits that make the ideal cost-effective solution.

Before You Think of Building a Garage

Before you get started on building a garage, it’s important to plan out exactly what you want and need from the finished structure. You should also make sure that you are setting aside enough time and money to cover all costs involved in the construction process.

How much this will actually be can vary greatly, depending on factors that include:

  • The size of the garage you want to build
  • The materials you want to build your garage from
  • Whether you’re planning on hiring a contractor or installing the garage yourself
  • Whether you need planning permission for your garage or not
  • Whether it will have a pitched or a flat roof

What’s Involved in Building a Garage?

No matter what type of garage you are planning on building for your property, there will always be a certain set of steps involved in planning out, building, and completing your garage:

  • Setting your budget
  • Planning your garage design and style (type of roof, single or double, extension or stand alone, etc.)
  • Getting quotes from tradesmen (if you are not planning on doing the work yourself)
  • Constructing the garage walls
  • Building the garage roof
  • Fitting the internals (such as electrical fittings, or cupboards and shelves)
  • Fitting security features

Getting Planning Permission for Garages

Whether or not you will need to pay for planning permission and get Building Regulations approval all depends on the size of your garage. Most small single and double garages, including extensions, are considered to be permitted development as long as they adhere to a certain set of guidelines.

Stand alone garages must:

  • Be no higher than 4 metres in height overall when built with a pitched roof
  • Be no higher than 3 metres in height overall if built with any other kind of roof (which falls to 2.5 metres if it’s located less than 2 metres from your property boundary)
  • Not take up more than half the land around the original property
  • Be located more than 2 metres from your property boundary

Garage extensions must:

  • Not be higher than the highest part of the roof
  • Not take up more than half the area of land around the original property
  • Not be forward of the principal elevation, or side elevation onto a highway
  • Not include any verandas, balconies, or raised platforms
  • Be made from materials that are similar or the same as the materials used to build the existing property

All of this information applies specifically to houses, rather than to flats or maisonettes, and planning permission fees vary depending on where you live in the UK (England, Scotland, or Wales). 

There may also be further stipulations that only apply in your specific area, so we would always advise that you get in touch with your local building authority before you start planning your garage. This could potentially save you both time and money on starting a project, only to find that it lacks the necessary permissions and will need to be torn down and started all over again.

The Different Types of Garage and How Much They Cost

For most types of garage, the cost to build and install them will differ, depending on the size and design, the materials used in the construction process, and the quality of the work carried out by the contractor. As such, prices for building garages can range between £4,000 and £50,000, and the overall cost is determined by what the purchaser asks for.

Below, we’ve set out a range of the average prices for some of the different garage material types in the UK:

Brick Garages

A single, low quality, brick garage with a flat roof that takes 10 days to build should start at around £4,500 to build. This is the most common type of garage extension picked out by homeowners across the UK, and may end up saving you money on maintenance and repairs in the long term.

However, you should also know that this type of garage will take longer to build than other material varieties. The time length can vary between a week and a month, depending on the contractor chosen and their skills and experience level. 

Single (Low Quality) with a Flat Roof

Build Duration: 10 Days

Material Costs: £1,400

Labour Costs: £3,100

Single (High Quality) with a Pitched Tiled Roof

Build Duration: 14 Days

Material Costs: £1,800

Labour Costs: £3,300

Double (Low Quality) with Flat Corrugated Roof

Labour Costs: £9,000

Double (High Quality) with Pitched Tiled Roof

Build Duration: Up to 1 Month

Material Costs: £4,500

Labour Costs: £13,500

You should also be aware that prices for brick garages may increase far beyond this, depending on the specifications and dimensions of your planned project.

Concrete Prefab Garages

Prefabricated garages (factory-made, kit garages) are often considered the easiest and cheapest method of installing a garage on your property, as they only take about a week to install when the work is done professionally. They’re usually made from concrete or metal, with slabs and plates joined together and installed on a concrete foundation. 

Starting prices for prefab kits begin at around £1,000 and can go up to £5,000, with the average price of a double prefab garage being priced at around £3,000. When involving labour costs, this means the cost to build a prefab garage could go up to £9,000.

Metal Prefab Garages

Metal prefabricated garages will normally be cheaper to buy, build, and install, but they are also less durable than other designs and will most likely only last for a few years. This is why you can typically buy a kit from an unknown brand for around £250, with prices increasing up to £2,500 or more for higher quality, more well-known brands.

If a metal prefab garage can be installed right away on a pre-existing concrete slab foundation, it should only take around two days to complete. However, if a foundation needs to be poured first, then this time increases to around a week.

Single (Low Quality) Prefab

Build Duration: 1 Week

Material Costs: £250

Labour Costs: £1,500

Single (High Quality) with a Corrugated Roof

Build Duration: 1 Week

Material Costs: £1,000

Labour Costs: £1,500

Double (Low Quality) Prefab

Build Duration: 1 Week

Material Costs: £1,500

Labour Costs: £2,000

Double (High Quality) with a Corrugated Roof

Build Duration: 1 Week

Material Costs: £2,500

Labour Costs: £2,000

Wooden Garages

If you’ve been looking for a quick, easy build that’s also more durable than a metal prefab, then a wooden garage may be the solution you need. With certain brands starting at £150 and increasing up to £2,000, you can also expect them to be cost-effective for your budget.

Like prefab garages, wooden garages can be installed on a property in a few days. This time will increase up to a week if you need to put down foundations first.

Single (Low Quality) Prefab

Build Duration: 1 Week

Material Costs: £200

Labour Costs: £1,500

Single (High Quality) with a Corrugated Roof

Labour Costs: £2,000

Double (High Quality) with a Corrugated Roof

Build Duration: 1 Week

Material Costs: £1,500

Labour Costs: £2,000

How Much Do Garage Doors Cost?

There are a number of different types of garage door you can choose from to add a unique, stylish appearance to your build, or to add an extra layer of security and safeguarding for your belongings. The most common, and the lowest priced, of these is the “up and over” type, which comes in both “canopy” and “retractable” varieties.

Typically, canopy and retractable varieties will cost between £150 and £300+VAT. If you wish to complete your doorspace using a more complex design, you may also think about installing a “roller” door, which will open from the bottom and roll up into a position in the top of the door opening. Standard roller varieties will normally begin at £500, but can increase to as much as £5,000 for the electrically-assisted varieties.

If you are in need of an affordable door design that can be utilised for storage purposes, you may wish to install “side hinged” door varieties, which usually start at around £200+VAT. These door types open in the middle, which means they will never enter your garage space.

You may also wish to opt for “sectional” doors, which split into horizontal panels, if you would prefer a modern design for your garage. The average cost of these doors is between £650 and £1,000.

How Much Do Garage Roofs Cost?

Like garage doors, there are also multiple options for garage roofs when you’re planning on starting a project on your property. The two most common designs are pitched or flat roofs.

A pitched roof can be angled on one or both sides, with the construction of the roof normally helping to determine what materials will be used to finish it. The materials most often used to finish pitched roofs include:

garage thatched roof
  • Felt
  • Corrugated sheet material
  • Tiles

The price of the roof can vary depending on the material used, with a single pitched roof single garage with a tiled roof starting at £5,000. The price will then increase with the size of the build and the quality of the tiles used.

These roof projects can take between 10 days and a month, depending on the quality of the finish and whether or not any specialist embellishments are required.

Flat roofs, on the other hand, are normally constructed from felt and tar that has been spread over a timber frame. These can often all be purchased together within a “flat roofing kit” for £250. Purchasing the items separately will usually take the price up to a total average of around £300.

Choosing an Extension or a Stand Alone

There are price differences to consider between stand alone garages and garage extensions, as having an attached garage built onto your home can increase the price because of the added labour costs. For example, a basic single detached garage may cost £4,500 for the combined costs of materials and labour, while an extension of the same size may cost around £4,800.

You should always hire a skip in order to carry out waste disposal when planning a garage project as well, which begins at around £150 for a week’s worth of use. Collection and waste disposal is normally included in this price.

Supply Only Costs of Building Materials

If you are planning on building the garage yourself, you will need to ensure that you are purchasing enough of each material to complete your project. We have made a list of some of the materials you may need to build your own garage in the UK, along with average prices:

  • Blocks: £100 per 54 block sets
  • Bricks: £500 to £1,000 per 500 bricks
  • Cement: £5 per bag needed
  • Corrugated sheets (plastic or metal): £100 to £150 for one 2.5 x 5m sheet
  • Sand: £50 per ton
  • Tiles: £1.85 to £5 per tile (a standard single garage roof normally holds about 1,000 tiles)

If you need to lay a foundation for your garage, you will also need a concrete slab. This is usually a mixture of cement, coarse gravel, and sharp sands. The amount of mix required will vary, but for an average depth of 30cm, you will most likely need around two tons of the gravel and sand mix, as well as five bags of cement. Altogether, this should cost around £125.

Additional Costs

There will always be additional expenses to cover when building a garage, particularly if you are planning on wiring the building for electricity, adding security features, and installing locks on the doors and windows. 

An electrician will be needed to fit the supply, which may cost between £125 and £150 a day, and they can either install further security systems such as lights (for around £50), alarms (for £100), and CCTV cameras (for about £150), or you can choose to hire a security specialist for a daily rate of around £150 to £200.

You may also need internal structures once the garage “shell” is fully built and installed, fitting cupboards and shelving units, with the price varying depending on whether you want to build and install the shelves yourself or if you would prefer to hire a carpenter to do the work. Hiring a carpenter should cost you between £100 and £150 a day, while buying the shelving to fit yourself can cost anywhere between £15 and £100, depending on the quality, the materials, and the number of units purchased.

When installing a garage, you will also need to consider arrangements for guttering, which should start at around £150 for a single garage, with the cost of a water butt for drainage starting at about £10. These are also easily installed by hand, so you should not need to pay any extra expenses on labour.

The final factor you will need to consider is whether or not you need to build a new driveway to accommodate your new garage. This can vary in price depending on the materials you choose, but if you decide on a concrete driveway the most cost-effective time to lay it will be at the same time that you choose to lay your garage foundations. This will likely extend the work on the foundation by around two to three days, at a cost of £75 people per day.

Hiring Specialists

When looking to hire tradesmen to carry out work, you will need to think of the specific tasks they need to complete to get the job done. As building a garage can have a range of different specialist work types attached, you may need to hire a variety of contractors to finish your garage project. We’ve listed some of the tradesmen you’ll need below, along with average prices for daily hire:

  • Architects or designers: £200 per day
  • Bricklayers: £75 to £100 per day
  • Concrete layers: £75 per day
  • Electricians: £125 per day
  • General builders: £100 to £150 per day
  • Tarmac layers: £125 per day (depending on skill level and qualifications)

Labour Costs and Timescales

Naturally, the longer any job takes to complete, the higher the final price will be at the end of the work. There are a number of factors which can have an impact on the timescale of a project, and therefore bring up the costs of labour:

  • The size of the build
  • The complexity of the build
  • The final quality of the build
  • The materials chosen to build the structure
  • The skill of the tradesmen hired
  • The amount of tradesmen hired to complete the project
