What sort of costs should you expect for a garage build?

When it comes to a garage, many people overlook the costs, and if you’re building a house, it’s not necessarily the thing you’ll think of first. By the time the home is built and funds are spent, it is often the external builds which suffer. That’s why it’s important to budget correctly when planning your garage. You might think of it as just a store room, but it can end up being an expensive one.

The Costs of a Garage

Your typical detached double garage will set you back approximately £18,000 at the very lowest end of the market. That’s a 36m² brick-built space that matches the design of the house and has walls that are 2.5m high, a concrete tiled roof and a ground-floor slab with trench-fill foundations. Two single garage doors, some drainage, a window and an electricity supply are also included in that price.

The above costings are for a very basic design of garage. It’s easy to see the cost increase if you decide to add extras, such as thicker walls, plumbing, garage shelving such as that found at https://www.garage-shelving.co.uk/ or even a better roof. These added extras can easily push the price up to £25,000 and beyond.

Check too if you need planning permission before you start the construction. Information about this can be found at the Homeowners Alliance. If you do need planning permission, be aware that it can be costly and complex to get.

Remember the above cost is calculated as if you are doing the project yourself. If you are going to get someone else in to do the job, you’ll have to add on the price of the contractor. Not only that, but you’ll also have to include VAT if the garage doesn’t qualify for zero-rated status – if you are constructing a new-build to add to an existing house.
