Whether you see it as quite a luxury, a functional storage area or the ultimate man-cave, adding a garage to your property can have many benefits. Not least the fact that it can add value when you come to sell.

However, if you’re thinking about building a garage, don’t underestimate the cost. Building a garage should be approached in the same way as if you were planning an extension to your house. But how much does it cost to build a garage?

As with all building projects, the cost can vary vastly from one project to another. But as a guide, for a basic detached, brick built double garage, you should be budgeting in excess of £18,000.

A figure in that region should get you a sturdy, stable, watertight garage with doors, electricity, a window and an access door. But if you want to include things like insulation, the cost only goes up from there. You may need planning permission – contact your local planning office before you start to find out. If you’re adding your garage to an existing property, there will also be VAT on top of that. And don’t forget, a new garage might necessitate a new driveway…

You may also want to hire someone to manage the project. They will find the right contractors and direct proceedings to keep everything on track, making sure the finished structure complies with any necessary building regulations. As a guide, garages are exempt from building regs if it is over 1m from the boundary and the internal floor area is less than 30m2 (or non-combustible if within 1m of the boundary).

Building a DIY garage

Don’t be fooled into thinking a garage is an easy DIY build. This is a big project. Unless you’re an expert builder, it’s likely to take you some time to complete and you may well have a few false starts and problems along the way.

However, if you’re a pretty competent DIY-er and have plenty of time on your hands, you could give it a go. You’ll may still need the work to be inspected and signed off (depending on size and location), and some elements, such as electrical installation, should still be carried out by a professional. But taking on the main planning and building elements yourself will save you some cash.

If you’re looking for a halfway house, you could manage the project yourself, but still rely on professional contractors to do the work. The £18,000 figure above doesn’t include the cost of project management, so it’s another slice of cost to consider. Another way to circumnavigate this cost is to find a main contractor who employs all the trades you need under one roof – just like us!
