Benefits of Converting Your Garage

The main benefit of undertaking a garage conversion is the creation of a space that can be utilised as you see fit.

Many growing families tend to view a garage conversion as the best viable option due to the fact it's far more cost-effective than buying a larger family home, or because they simply don't want to leave their current home despite feeling they have outgrown it. 

The choices are endless with a garage conversion, and it all comes down to what you need to use the space for.

The most popular choices include extending the kitchen area into a large open plan kitchen diner, creating a home office, adding a new entertainment or games room, and creating an entire new liveable space such as a bedroom with ensuite or entire granny annex with its own mod cons.


The benefits of a garage conversion aren't just practical, as there is also the potential for plenty of financial gain.


Any type of property conversion is likely to add significant value when constructed to a high standard by a reputable building company, and they are always appreciated by home buyers - particularly within a family home.

How long does it take to complete a garage conversion?

The amount of time needed to complete a garage conversion is highly dependent on several things, but a relatively small and simple garage conversion can reach completion within just a week or so. Larger or more complicated garage conversions may run into a few weeks, or in special cases even longer. As a general rule of thumb, most standard garage conversions reach completion within two weeks.

How much does a garage conversion cost?

There are many things to consider when we work out the cost of a garage conversion, and with each project potentially differing massively from the next, it's impossible to provide an average ballpark figure for a garage conversion.


Fortunately, we do offer a free quotation, so feel free to get in touch with us so that we can discuss your garage conversion needs in more detail and provide you with an accurate quote.

Why should I convert my garage?

Most people choose to convert their garage because they need the extra space, or because they have a specific room in mind that they'd like to add to the property (gym, guest room, cinema room, work or office space etc.)


Some even choose to shuffle rooms around, by converting a garage into a kitchen and then the original kitchen into a more spacious living room, for example.


Not only can a garage add significant space to your property, it can also add value. The majority of driveways are now used to store cars, meaning the need for a garage is decreasing every day. Transforming your garage into a usable room can be beneficial for the entire family, as well as your pocket when it comes to selling further down the line.


Do I need planning permission to convert my garage?

In most cases, planning permission is not required to convert your garage, providing the work is internal and doesn't involve making the property bigger.


In some rare cases permitted development rights may have been removed, and this could prevent a garage from being legally converted without obtaining planning permission. For this reason, it is always worth double checking, and we will do this for you.


If the property is a listed building, then listed building consent may be required.
