Garage Conversions South Wales | Transform Your Underused Space

Transform Your Garage into a Beautiful, Functional Space

Many homes in the UK have garages that are underused, cramped, or simply storing clutter. At Adfer Cymru, we see the potential in every garage. With the right planning and expertise, these spaces can be transformed into fully insulated, habitable rooms that add value, comfort, and practicality to your home.

Whether you dream of a bright home office, a family-friendly playroom, a home gym, a cosy den, a yoga studio, a gaming room, an extra bedroom, or even a kitchen extension, we turn your ideas into reality — handling every detail from start to finish.

Why Choose a Garage Conversion?

A garage conversion can be one of the most cost-effective ways to extend your living space. Unlike traditional extensions, they often avoid the need for expensive groundwork, planning delays, or major structural work.

With the right expertise, a garage conversion can:

Increase your home’s usable space without the disruption of a full extension
Provide a modern, insulated, and comfortable environment
Add value to your property while making it more functional
Create bespoke spaces tailored to your lifestyle

At Adfer Cymru, we ensure your conversion is fully compliant with building regulations and planning requirements where necessary. Every project is handled with the care, precision, and honesty our clients have come to expect.

Frequently Asked Questions

Do I need planning permission for a garage conversion?

In most cases, a standard garage conversion within the footprint of your home does not require full planning permission, as it is classed as a permitted development. However, exceptions apply, particularly if your property is listed, in a conservation area, or if you plan significant changes to the building’s exterior. At Adfer Cymru, we guide you through the planning process and liaise with local authorities where necessary to ensure your conversion is fully compliant.

Will my garage conversion increase the value of my home?

Yes. A well-designed, fully insulated, and functional garage conversion can significantly enhance both the liveable space and the overall value of your property. By creating a versatile room — whether a bedroom, home office, or extension to your kitchen — you make your home more attractive to future buyers and improve its functionality for your family now.

Can all garages be converted into living spaces?

Not all garages are ideal candidates. In some cases, single garages may be too narrow, low, or structurally unsuitable for certain uses, while detached or shared garages may require additional permissions.

At Adfer Cymru, we assess each garage carefully, considering dimensions, structural integrity, and building/planning regulations, then recommend the best use for the space.

How do you handle insulation and energy efficiency?

Converting a garage into a comfortable, habitable room requires proper insulation, ventilation, and heating. We use high-quality insulation in walls, floors, and ceilings to meet building regulations, helping to maintain a comfortable temperature year-round and reduce energy costs – good for your pockets and for the planet. We also ensure that windows, doors, and heating systems are appropriately specified for the space.

How long does a typical garage conversion take?

The duration depends on the complexity of the project. Simple conversions, such as creating a home office or den, can take 4–6 weeks, while more complex projects — involving plumbing, kitchens, or bathrooms — may take 8–12 weeks. Ian oversees every stage, ensuring smooth progress and clear communication throughout.

Do you handle all aspects of the work, or will I need separate tradespeople?

Absolutely! We manage every stage of the project from start to finish, including coordinating various specialists. This includes plastering, carpentry, plumbing, electrics, heating, flooring, windows, doors, and more.You will have one point of contact — Ian — who coordinates all trusted and vetted tradespeople to deliver a seamless, high-quality conversion.

Can I convert a garage into a room with plumbing or a bathroom?

Yes. Many garage conversions incorporate bathrooms, wet rooms, kitchens, or utility areas. Our team ensures that plumbing, drainage, and electrics are installed to UK building regulations, creating fully functional and safe spaces tailored to your needs.

Will a garage conversion be comfortable in winter and summer?

Yes — provided insulation, heating, and ventilation are properly installed. Our conversions are fully insulated, with appropriate flooring, walls, and ceilings. We also specify heating systems suited to the room, ensuring it remains comfortable in all seasons.

How much does a garage conversion cost?

Costs vary depending on the size of your garage, the scope of the work, and the level of finish desired. At Adfer Cymru, we provide transparent, detailed quotes upfront, with no hidden costs. We focus on delivering value by combining quality materials, expert craftsmanship, and efficient project management.

To get an accurate quote for your individual project, simply get in touch.

Can I continue living in my home during the conversion?

In most cases, yes. Garage conversions are mostly self-contained projects, and we coordinate trades to minimise disruption.

We will usually need to knock through from your main property into your garage (unless you already have suitable access) so there may be some disruption here, but we will keep this to an absolute minimum, respecting your home.

We keep work areas clean and safe, communicate schedules clearly, and plan each stage to allow you to continue your daily routine with minimal interruption.
