Do I 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.

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.
Ideas For A Garage Conversion
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. These can apply whether you’re searching for garage conversion exterior ideas, ways to revamp a single garage, or larger-scale double garage transformations.
Detached Garage Conversion Ideas
A detached garage gives you a great opportunity to create a completely independent living or working space. Since these garages are separate from the main house, they’re ideal for conversions that benefit from privacy, such as guest suites, home offices, or even small rental units. You could add plumbing and insulation to transform your detached garage into a self-contained studio with its own entrance. Alternatively, create a peaceful garden office surrounded by greenery, making the most of the separation from your home. Just keep in mind that detached garage conversions often require planning permission, so check with your local authority before starting work.

Single Car Garage Conversion Ideas
If you’re working with a single garage, smart design is key. Think vertical storage, multi-functional furniture, and plenty of natural light to make the most of your compact space. A single garage can easily be transformed into a home office, utility room, or small gym. You could even create a cosy reading nook or mini cinema room. With thoughtful layout choices, a single car garage conversion can feel surprisingly spacious and become one of the most functional areas in your home.

Double Garage Conversion Ideas
Double garages offer far more flexibility, giving you the space to create multiple zones or even two separate rooms. Many homeowners choose to split the area into a combination of a bedroom with an en-suite and a home office, or a gym and games room. The extra square footage means you can also add more luxurious finishes—like underfloor heating, skylights, or bi-fold doors—to bring in natural light and make the space feel high-end. If you’re looking to maximise both your property’s value and functionality, a double garage conversion is one of the most rewarding options.
Garage Conversion Exterior Ideas
When converting your garage, don’t forget about curb appeal. A well-designed exterior can make your conversion look seamless and intentional, rather than an obvious add-on. Consider matching materials, such as brick, cladding, or paint colour, to the main house for a cohesive look. Replacing the old garage door with large windows or patio doors can flood the space with light and create a stylish modern façade. Adding exterior lighting, landscaping, or a small porch can also enhance the overall look of your home and increase its value even further.
