Barn Conversion Builders in Somerset
Converting a barn is a unique opportunity to create a home that is entirely one-of-a-kind. We deliver professional barn conversions in Somerset and across the South West, preserving the rugged, historic character of the original structure while integrating the high-performance comfort of a modern home.
Our Specialist Barn Conversion Services
A barn conversion is more than just a renovation. We provide the specialist skills required
to handle the heavy lifting of a heritage build while ensuring a refined, high-end finish.

Structural Stabilisation
Many barns require sensitive “back-to-brick” or stone-by-stone restoration. We ensure the skeleton of the building is sound before the transformation begins.

Heritage Stone & Lime Work
We use traditional materials, including local Somerset stone and lime mortar, to ensure the building remains breathable and compliant with conservation standards.

Infrastructure & Utilities
We manage the installation of modern essentials, utilities, and infrastructure without compromising the building or the surrounding area’s original aesthetic.

Bespoke Joinery
From sweeping oak staircases to traditional stable-style doors, and bespoke hand-crafted cabinetry – our in-house joiners create custom pieces that fit the unique proportions and aesthetic of your barn.
Frequently Asked Questions
Unfortunately, not every barn is a candidate for conversion. For a successful project – especially under Class Q Permitted Development – the existing structure must be “strong enough to take the load” of a residential fit-out without requiring a completely new internal frame.
During our initial site visit, we assess the foundations, the verticality of the walls, and the roof structure to give you an honest appraisal of the building’s structural feasibility.
Class Q is a specific path that allows the change of use of agricultural buildings to residential dwellings without a full planning application. It is often faster but has strict limitations on the size and appearance of the final home. Full planning permission is usually required for listed buildings or those in conservation areas.
Because we’ve worked in the Somerset and South West districts for nearly 40 years, we can work alongside your architect to advise which route offers the best chance of success for your specific site.
Absolutely! Our heritage specialists are experts at “blasting” old timber to reveal its natural grain and repointing local stone using traditional lime mortars. We focus on a sympathetic restoration, ensuring that the modern structural reinforcements – like steel frames or new floor joists – are either hidden or used as industrial-style design features that complement the building’s history.
This is the biggest challenge in barn conversions across the South West. We use several specialist techniques, such as internal wall insulation (IWI) using breathable materials like wood fibre or lime-based systems. This allows the exterior stone to remain untouched while creating a thermally efficient home. We also focus on high-performance roof insulation and floor membranes, ensuring the building meets modern thermal standards without losing the charm of exposed masonry.
Navigating the Planning Process
Whether your project falls under Class Q Permitted Development or requires Full Planning Permission (particularly for listed buildings), we have the experience to help.
We work collaboratively with your architects and local planning officers to ensure the design intent is met while satisfying all regulatory requirements.
