Cost to Build a Garage

What the job entails

Building a garage is a popular home improvement project, especially in the UK where car crime is prevalent and insurance companies will reward you with lower premiums if vehicles are garaged overnight. Garages are great for your car too, even in the UK the sun will dull paintwork over time, and parking your car outside means more bird droppings, rain, sleet and snow - all of which can cause havoc with the paintwork! So garages protect your car and contents, from both criminals and the terrible UK weather, it's no wonder they are so popular as a home improvement project. This article will help you to understand what is actually involved in building a garage, while offering typical costs both for DIY and when hiring a builder, so if you are considering perhaps adding a garage, you can understand at a glance exactly what this will entail.

If you require power/lighting in your new garage, then you need to hire an electrician that is registered with the Registered Competent Person Electrical scheme so that the electrical work done will comply with Part P building regulations.

You may also consider require a builder or landscape gardener to build a garden path from house to the garage if detached, plus of course a driveway from the new garage to the kerb/road.

There are regulations governing the building of garden outbuildings which apply to sheds, greenhouses and garages as well as other garden structures including sauna cabins, kennels, summer houses and many other kinds of building which are considered incidental to the enjoyment of the main dwelling-house. However, most outbuildings are considered to be permitted development, so do not require planning permission, subject to certain conditions. Outbuildings which are single storey, which do not include balconies, verandas or raised platforms, which occupy no more than half the area of land around the original house, which are less than 2.5m high and which are not within the curtilage of listed buildings; will generally not require planning permission.

If planning an expensive brick-built garage, you may also consider building an extension with an attached garage. An well planned extension will definitely increase property value and you will probably recoup all costs when you come to sell the house, whereas this is not always the case with detached garages. Simple single or double garages built using a prefabricated kit, are pretty easy to build and fall well within the scope of the DIY enthusiast. Whereas a brick built outbuilding will require much more in the way of skills and equipment and should perhaps be left to the professionals.

Don't be tempted to skimp on costs with outbuildings, any building which is expected to last in the awful UK weather for any length of time, will need to be sturdy with a proper concrete foundation. Even though laying the concrete foundation can be the most labour intensive part of the job, particularly with prefabricated kits for garage buildings. But be very careful to ensure that there are no pipes or cables in the area before you start digging out foundations, a small single garage project could easily turn into an expensive (and dangerous) nightmare if you cut through a power cable or rupture a gas or water pipe!

You can perform many types of work without needing to apply for planning permission, in most cases, outbuildings such as single storey garages, sheds or summer houses will come under permitted development and will therefore not require planning permission. That being said, before planning any building project, you should always check with your local planning department to find out if if planning or building regulations apply in your circumstances. This is your responsibility, even when you hire a contractor, so always double check even if builders tell you planning is not required.
Most types of building will need a substantial base which should be solid, flat and level. Paving slabs or concrete are the most common but a solid concrete base is more permanent (but also more expensive) but could be suitable for small single garage timber projects.
