Listed Building Conservation
& Conversion in Somerset
Working on a listed building requires more than just construction skill; it requires a deep respect for history and an understanding of traditional materials. We provide listed building conservation and conversion in Somerset and across the South West, ensuring your property is protected for future generations.
Specialist Heritage Services
Our directly employed team of specialists includes tradesmen skilled in traditional
techniques that many modern builders have lost. We manage the delicate balance
between structural integrity and historical accuracy.

Conservation & Restoration
We provide essential repairs using period-correct materials. From the careful restoration of timber frames to the use of traditional lime mortars and plasters, we ensure the repairs are sympathetic and breathable.

Sympathetic Conversions
Converting a listed building – whether it’s a former mill or a large manor house – requires a specialist touch. We work to repurpose historic spaces while maintaining the original features that give the building its Grade I or II status.

Heritage Joinery & Timber Work
With a founder who is a carpenter by trade, our joinery standards are second to none. We specialise in the repair and replication of historic windows, doors, and structural beams, ensuring that we stay true to the original.

Structural Stabilisation
Older buildings often face unique structural challenges. We provide expert stabilisation and “back-to-brick” restoration that respects the original construction methods while ensuring the building is safe and sound.
Using the wrong materials for listed building conservation and conversion can trap moisture
and cause long-term damage to older structures. Our team is trained in the application of:

Lime Mortars & Renders
These mortors and renders are essential for allowing the walls of an old home to breathe and prevent damp and future damage.

Local Hamstone & Blue Lias
We source and work with authentic local stone to ensure any repairs or house extensions are identical to the original.

Traditional Joinery
Custom-crafted timber windows and doors that meet conservation standards while improving your home performance.
Frequently Asked Questions
Almost any change that affects the character of a listed building required consent. This includes changing windows, removing walls, or even certain types of repointing. We can help you identify what needs approval and work with your architect to secure it.
Standard uPVC or modern double glazing is almost never permitted in listed buildings. However, conservation officers often allow “Slimlite” vacuum glazing or high-quality secondary glazing that sits inside your existing frames.
As part of a Somerset listed building renovation, we can work with specialist joiners to repair original sashes or create bespoke timber replacements that satisfy both conservation requirements and your need for thermal efficiency.
There is no one-size-fits-all answer, but as a general rule, a listed building renovation typically costs 30% to 50% more than a standard modern home renovation. For a high-quality heritage project, you should budget anywhere from £2,500 to £4,500+ per square metre.
These costs are driven by the need for specialist materials and the slower, more meticulous pace of work required to protect the building’s fabric.
For private residential homeowners, direct grants are unfortunately quite rare and are usually reserved for buildings on the “Heritage at Risk” register or those owned by non-profits and charities.
