In 2023, there was a 180% increase in garage-to-office conversions compared to 2019.

So, if you’re looking for your next renovation project, you’re in luck because, in this article, we’ll be walking you through our top seven garage conversion ideas. From home gyms to your ideal workspace, read on to get inspired.

Do You Need Planning Permission For A Garage Conversion?

In most cases, you won’t need planning permission to convert a garage because they are considered permitted developments, provided the building meets certain requirements. However, those living in a designated area, such as a Conservation Area, Area of Outstanding Natural Beauty or National Park, will usually be required to obtain planning permission. If you live in a listed building, you will need to seek Listed Building Consent. Check out our article on how to get planning permission if you think you might need approval from your local authority.

Sometimes, restrictions are put in place when a property is constructed, which means the garage must be retained as a place to park. If that’s the case for your property, you’ll need to submit an application to have the restriction removed. Additionally, if you’re converting a detached garage, as opposed to an integral one, you’re more likely to require planning permission as outbuildings must follow different criteria to extensions.

As with any construction project, it’s best to consult with your local authority to check where you stand before beginning any building work. We recommend obtaining a lawful development certificate to confirm to you, the local authority, and any future buyers of your property that your garage conversion was carried out in accordance with the correct planning procedures.

If you have any questions regarding obtaining planning permission or any other approvals, do not hesitate to contact our team. With years of experience, we would happily assess your project and let you know what is required to get started.

Attached Garage Conversion

Attached garages are conjoined with the house at the side or rear. They’re the most common garage type in the UK and the simplest to convert. Because they’re already attached to the home, they usually run on the same electricity supply with some basic instalments already. Also, any new pipework can easily be run from the main house. Those with an attached garage have the option to knock down the dividing wall and create an open-plan space. The average attached garage conversion will cost between £10,000-£20,000.

Integral Garage Conversion

Like attached garages, integral garages are already connected to the home, but they slot into the profile of a property rather than joining at the side or rear. They’re the cheapest to convert and can easily be integrated because they’re already within the property. The average integral garage conversion costs between £10,000-£14,000.

Detached Garage Conversion

Garages that aren’t attached to the home are the hardest and most expensive to convert because they don’t run on the same water, gas, and electric supply. Building trenches for these lines and pipework is often labour-intensive. Detached garages sometimes require a reinforced frame, further increasing conversion costs. Despite this, a detached garage is a great way to create a space away from the home for working, exercising, relaxing, or any other way you plan to use your space. The average detached garage conversion will cost between £15,000 and £25,000.

    Will A Garage Conversion Add Value?

    Converting your garage will add value to your home because you’re adding valuable extra living space to the property. Garage conversions are generally less expensive than extensions and quicker to complete, so they’re great value for money when compared to other value-boosting renovations.

    It’s important to budget appropriately so you spend less on the conversion than the amount of value it adds to the property. Our architectural technicians are highly experienced in garage conversions, so if you’re looking for budgeting support, get in touch.

    If done well, a garage conversion can increase the value of your home by up to 20%. Garage-to-bedroom conversions with an en-suite bathroom generally add the most value, while garage-to-office conversions typically increase value by around 10%. The value increase you’ll achieve with your conversion depends on the type of property and what type of conversion complements it best.

    Garage Conversion Inspiration

    Now that we’ve covered the logistics of a garage conversion, it’s time to get inspired. We’ve compiled our seven favourite conversion ideas to help you decide how you’ll use your extra space.

    An All-In-One Living Space

    Use your conversion as an opportunity to create a home away from home. This conversion, packed with everything you’d need in a house, is perfect for a detached garage. These homeowners have added insulation, plumbing, flooring, and a cleverly designed sleeping loft to turn their garage into a cosy abode. They’ve repurposed lockers and used vintage furniture to create a stylish space while keeping costs down. Bear in mind that building regulations are required if you plan on using your garage as sleeping accommodation.

    A Productive Workspace

    If you work from home, you’ll know how difficult it can be to switch from work mode to home mode when you clock out for the evening. But with a garage-to-office conversion, you can create a space seperate from your home dedicated entirely to work. In this conversion, the homeowner has opted for a neutral palette and minimalist decor to create a relaxing environment that is great for productivity.

    Somewhere To Get Your Sweat On

    A garage-to-gym conversion is one of the simplest ways you can reinvent your garage space. Requiring far less investment than other conversion types, a garage gym makes it much easier to fit working out into your routine. Save on a gym membership and boost the value of your property at the same time- it’s a win-win!

    The Ultimate Games Room

    For those often on hosting duties, a garage conversion is the perfect opportunity to create a space your guests will love – a games room. From table tennis to pool, there are plenty of options to choose from, and the costs are relatively low compared to other conversion types. Or, if you’re looking to create a dedicated space for the kids to enjoy themselves, why turn your garage into a playroom?

    A Place To Be As Loud As You Want

    Those with a budding musician in their family will appreciate this one! Turn your garage into a recording studio where noise isn’t an issue. Whether you make music professionally or just enjoy getting creative with sound, this type of conversion is right up your street. Introduce sound-proofing technology and make use of the extra storage to create a space centred around great music.

    Something Worth Showing Off

    Before conversion, garages are often neglected and hidden from the rest of the house. So why not use this opportunity to turn it into the centrepiece of your home? In this remodel, the homeowners transformed their overly cluttered garage into the property’s master bedroom. Spacious and flooded with natural light, the new space is hardly recognisable.
