There’s quite a luxury in having a garage. The best aren’t only a place to secure your car, but function as a storage space for bikes, gardening equipment and other bulky items too. Some garages might even have a small toilet and an area to work.
When you’re drawing up your budget for external builds and projects, it’s extremely easy to underestimate the costs of building a garage. It’s just a single-story box, right? Wrong. You should treat garages in the same way you’d consider an extension, and so you’ll need a budget to match.
So, what is the cost of building a garage?
For an extremely basic detached and double garage, you should be prepared to pay at least £18,000. Though this might sound expensive, it actually only covers the mere essentials. A budget of this scale allows you to build a 36m² garage that’s brick built, matches the style of your home and measures 6m wide, 6m deep and 2.5m high. Assuming you’re installing two single garage doors, a little rainwater drainage, a simple electrical supply, a window and a personal access door, the breakdown of figures should be as follows.

- Trench fill foundations to a standard depth of 1m – £2,520
- Pour a simple ground floor slab, lightly reinforce and backfill – £2,700
- Construct four external walls, adding steelwork, lintels and piers as needed – £3,900
- Build roof structure – £1,190
- Cover roof in felt, battens and tiles – £1,260
- Include fascias, gable claddings, soffits and a barge board – £1,350
- Provide guttering and drainage – £1,200
- Add a small electrical provision, including running cables and an outlet – £1,000
- Integrate two garage doors, window and access door – £3,000
- Cover additional extras such as paintwork, security and shelving – £500
- Total cost – £18,620
With this budget, you’d be able to construct a watertight, functioning and very simple garage. However, many of the standard requirements aren’t included. For example, the walls included in the above quote are only half a brick thick. If you wanted to construct cavity walls and include insulation, you’ll need double the brickwork at a minimum. Meanwhile, the roof pitch quoted for is at a 25° angle; if you need this higher for aesthetic reasons, you can expect to pay more. In addition, once you add extra plumbing for a tap, a better roof covering and seal the concrete slab, your budget can rise to at least £25,000.
Other Cost Considerations
When you’re working out the cost of a garage, it’s important to remember there are other expenses involved in addition to materials and building costs. For example, the average prices already mentioned don’t include the cost of a project foreman.
If you’ve got no intention of managing the build yourself, you’ll have to pay someone to do it. You may also need to gain planning permission for the project, and this could come hand in hand with its own costs, particularly if approval isn’t given straight away.
In addition, if you’re adding a garage to a property that’s already in place, you won’t qualify for a zero VAT rated status. As a result, you’ll need to add VAT on top of your project.
Consider a DIY Project
If you’re looking to keep costs down, then you might consider building the garage yourself. There should be no illusions; this is a big project. However, because it’s not part of your main home, there’s the luxury that you can just shut the door and continue the build at your own pace. On the downside, unless you’re an expert builder, it’s likely to take you some time to complete.
But if speed isn’t a problem, doing the work yourself could be ideal. You’ll still need the completed work to be inspected and signed off by a professional, and some work, such as the electrical components, will need to be completed by a professional. However, by using Quotatis to find local contractors, you can negotiate costs for these individual jobs and still save a lot of money this way.
Building a garage isn’t cheap, and it’s essential to look at it as a major extension project rather than some simple external work. However, done right and with a careful hold on the budget, you can create a beautiful garage for under £20,000.
