Conversions in Somerset
Sometimes, the extra space you need isn’t found in an extension, but within the walls you
already own. We specialise in high-quality house conversions across Somerset and the
South West, transforming underutilised barns, lofts and garages into functional living spaces.
Our Specialist House Conversion Services
House conversions present a unique set of challenges – from matching masonry to upgrading
thermal performance without losing floor space. We bring nearly 40 years of experience
to these complexities, providing the heavy-lifting required to future-proof your building.

Barn & Outbuildings
Somerset is rich with historic agricultural buildings. We specialise in barn conversions that preserve original features while integrating modern technology. We understand the requirements involved in bringing these heritage structures into residential use.

Loft & Attic Conversions
A loft conversion is one of the most cost-effective ways to add a master suite, home office, or extra bedroom without sacrificing your garden. We handle everything from structural floor reinforcement to bespoke staircases.

Garage
Conversions
If your garage is currently just a storage space for clutter, it could be transformed into a high-value, added living space to your home. We transform integrated or detached garages into guest suites, playrooms, or professional home studios.

Basement & Cellars
Transforming the space beneath your feet into a high-value living area requires the highest level of structural expertise. We handle the complex engineering of basement conversions in Somerset and across the South West.
Frequently Asked Questions
It depends on the type of conversion. Many garage and loft conversions fall under Permitted Development, meaning you don’t need full planning permission.
However, Barn Conversions and projects in Conservation Areas or Listed Buildings almost always require formal consent. We can help you navigate these rules and ensure your project is fully compliant.
According to 2025 market trends, a well-executed loft conversion can add up to 20% to the value of a property, while a garage conversion typically adds 10–15%. Beyond the financial gain, it provides the vital extra space that prevents the need for a costly move.
In most cases, yes. For loft and garage conversions, we can often isolate the work area to minimise dust and disruption to your daily life. For more intensive projects, like a basement conversion or a total barn renovation, living on-site can be more challenging due to utility shut-offs or structural work.
During our initial consultation, we’ll discuss a phased approach to see how we can keep your home livable for as long as possible.
This is where our in-house civil engineering team really shines. If you’re converting an isolated outbuilding or a garage into an annexe, we handle the trenching and utility management required to bring water, waste, and power from the main house.
We manage the entire lifecycle of your house conversion in Somerset, ensuring all services are tucked underground and fully certified.
