Every building has a diagnosis
before it has a design.

We trace lime mortar joints, map cracked crown glass, and date hand-adzed oak beams — then write the next chapter without erasing a word.

Selected Projects

Three centuries of fabric,
extended by another.

Each project is annotated with the specific conservation philosophy applied — because method matters as much as outcome.

Grade IWiltshire·14 months·Faculty · Historic England · LBC

St. Margaret's Parish Church

Nave roof reconstruction & lime render reinstatement

Medieval stone church with failed render patches and moss-covered roof tiles showing water damage
Before
Scaffold erected around church nave, conservator applying lime render by hand to cleaned ashlar
During
Restored medieval church with clean lime-washed render, intact slate roof, and clear gutters at dusk
After
Conservation Philosophy

Minimal Intervention

Method

All failed render was mapped and sampled before removal. New lime work matched original Hot Lime specification from 1742 datestone evidence.

Outcome

Nave now weathertight for the first time in 40 years. Faculty granted in 8 weeks. Parish avoided urgent works notice.

Grade II*Bath·9 months·LBC · Bath & NE Somerset LPA

No. 14 Queen Square

Sash window restoration & Bath stone façade repair

Georgian Bath stone townhouse facade with cracked masonry, failing sash windows and peeling paintwork
Before

During

After
Conservation Philosophy

Like-for-Like Repair

Method

All 22 sash windows retained and repaired using traditional joinery methods. Crown glass sourced from the only remaining UK manufacturer.

Outcome

Enforcement notice discharged. All original glass retained. Property value protected and thermal performance improved by 38%.

Grade IHerefordshire·26 months·LBC · Historic England · Conservation Management Plan

Ashford Park Estate

Structural stabilisation & Conservation Management Plan

Derelict Georgian country house with failing parapet, collapsed section of roof and overgrown grounds
Before
Structural engineers and conservators reviewing measured drawings inside partially stabilised country house
During
Stabilised Georgian country house with repaired parapet and roof, surrounded by restored formal gardens
After
Conservation Philosophy

Reversibility

Method

All structural interventions designed to be reversible. No chemical consolidants used. Stainless steel ties concealed within original mortar joints.

Outcome

At-risk status removed from Heritage at Risk Register. Estate trust now has a 25-year phased repair programme with pre-agreed consent framework.

Our Approach

From diagnosis to craft
to lasting stewardship.

Diagnosis

We read buildings before we prescribe.

A crack in an elevation tells a story about settlement, drainage, or differential movement across centuries. We interpret that story before a single specification is written.

Every commission begins with a Condition Survey — a measured, photographed, and annotated record of everything the building is telling us.

Craft

The right material, sourced from the right place.

Lime mortar must breathe with the masonry it binds. Imported hydraulic lime will not serve a wall that has moved on hot lime for three hundred years. We specify by analysis, not by catalogue.

We maintain relationships with traditional material suppliers — lime burners, lead workers, crown glass fabricators — whose methods match the buildings we serve.

Stewardship

A repaired building needs a maintenance plan.

The most expensive repair is the one that becomes necessary because the previous repair was never followed. We write maintenance schedules alongside every Conservation Management Plan.

Our clients receive a 25-year phased programme: what to inspect, when to repoint, how to identify early warning signs before they become emergencies.

“We don’t restore buildings to how they looked. We restore them to how they worked.”

— Practice Principle, Conserve
Begin Here

Every project starts with
a conversation about the building.

Request a Condition Survey

Our surveyors visit your building, produce a written condition report, and recommend the most cost-effective sequence of repairs — typically within three weeks of enquiry.

We respond within two working days. No automated responses — a conservator reads every enquiry.
