Garage Conversions - Extra Space and Added Value

Updated: Jan 17

At Asset, we don't just convert lofts, we work on all types of extensions, one of the most popular types being garage conversions. Giving an underused garage a makeover can unlock precious space in your property and increase its value.

We find that the most popular reason and main benefit of a garage conversion is to add extra living space. This could include converting a garage into an open-plan living area, creating an extra living room or extending a kitchen.

However, adding another bedroom could be the best option in terms of creating value in your home. Garages are also often converted into office space, a gym or a playroom. You could also create an annexe for an elderly relative or to bring in some extra income as an Airbnb rental.

According to a report by bank Santander, of the 9.3 million private garages in the UK, 650,000 have already been turned into bedrooms (the most popular choice, at 29%), as well as home offices, kitchen extensions, utility rooms or sitting rooms.

Will you need planning permission to convert your garage?

Planning Permission isn’t usually required for a garage conversion, provided the work is internal and doesn’t involve enlarging the building.

Garages that are listed or located in conservation areas will be less straightforward to convert. In all cases, your conversion will have to comply with Building Regulations.

You may, however, require Planning Permission if you want to turn your garage into a separate home, or if you live in a listed building, conservation area, new housing development, flat or maisonette.

Some councils will also require Planning Permission if you’ll be substantially changing the exterior of your house.

Garage conversions will need Building Regulations approval. However, Local Authority Building Control (LABC) advises that a Full Plans application will provide more security about what work needs to be done.

LABC also advises speaking to an architect or building contractor before beginning the work and you will need to consider the rules around party walls.

There are a number of areas in the regulations your conversion will need to comply with. These include:

  • Foundations

  • Structural strength

  • Windows and ventilation

  • Weather-proofing and insulation

A building control surveyor will inspect the work as it progresses and once it’s finished, they will check windows, fireproofing measures and doors before giving a certificate of completion.

Value added

There are lots of factors to consider when looking at how much value a conversion adds – for example, what you turn the space into and the amount of room on offer.

Converting a double garage is obviously going to add more value than a single garage. But on a standard three-bed semi, a garage conversion will increase its value by at least 10%.

However, the real value is often the extra space it will give to your family to enjoy spending time in for years to come.
