Heritage Conservation & Restoration Specialists
We specialise in the repair, conservation and sensitive extension of historic and listed buildings based in Northamptonshire, Leicestershire and Buckinghamshire — delivering multi‑trade construction grounded in structural understanding, traditional materials and a deep respect for each building’s fabric.
We are a specialist building firm with decades of technical, hands‑on experience across the UK and overseas. Our work spans the full spectrum of traditional construction — from the conservation of listed and historic buildings to complex structural repairs, barn conversions, sensitive extensions and traditionally built new homes.
Our background is rooted in heritage craft and building science. We understand how older structures behave, how traditional materials should be used, and how to carry out repairs that respect a building’s fabric while ensuring long‑term performance. Every project is approached with precision, care and a deep respect for the architecture we’re entrusted with.


We focus on projects where skilled craftsmanship and heritage knowledge genuinely make a difference — including Grade I, Grade II and Grade II* listed buildings, traditional stone or brick farm buildings, oak‑framed barns, and period homes across Northamptonshire, Leicestershire and Buckinghamshire. Our work covers heritage restoration, barn conversions, traditional new builds, full renovations and high‑quality interior fit‑outs using appropriate materials such as lime mortars, hardwood joinery, natural stone and breathable insulation systems. We take on a manageable number of projects each year to ensure each one receives the attention and precision it deserves.
A heritage builder specialises in repairing and improving older buildings such as listed properties, stone houses, barns and period homes across Buckinghamshire, Northamptonshire and Leicestershire. This includes traditional stone masonry, lime repointing, stone renovation, structural repairs and sympathetic extensions that protect the building’s historic character.
At Pear Tree House Construction, this is our core focus. As a family‑run team with over 30 years’ experience, we work almost exclusively on heritage and traditional properties, using the correct materials and methods for each building. We understand local stone types, conservation requirements and the level of care older buildings need.
Homeowners, architects, surveyors and estate managers choose us because we combine heritage craftsmanship with a reliable, flexible on‑site approach — delivering work that respects the building’s fabric while achieving a high‑quality finish.
Yes. A large proportion of our work involves listed buildings, conservation‑area properties, period homes and agricultural buildings with architectural or historic significance. We use conservation‑led methods such as lime plastering, lime pointing, traditional timber repairs, stone replacement, breathable construction systems and sympathetic structural reinforcement. We understand the care required when working with older fabric, including managing moisture movement, preserving original features and complying with conservation officer requirements.
We primarily work across Northamptonshire, Leicestershire and Buckinghamshire, including rural villages, conservation areas and estates with historic building stock. We also take on selected projects further afield — particularly those involving heritage restoration, barn conversions or complex structural work — when the project aligns with our specialist skills.
Yes. We regularly collaborate with architects, conservation architects, surveyors, structural engineers and heritage consultants. We follow drawings precisely, communicate clearly and work in a way that protects the design intent, material specification and conservation requirements from start to finish. Our experience with traditional materials and heritage construction methods helps ensure the project progresses smoothly and respectfully.
We are typically booked several months ahead. This allows us to maintain high standards and give each project — especially those involving listed structures, structural alterations or specialist materials — the time and planning they require. If your project has a specific timeline or involves heritage constraints, we recommend getting in touch early.
We take on small, medium and large projects where skilled craftsmanship is essential — including full renovations, heritage restorations, barn conversions, structural repairs, traditional new builds and estate property upgrades. Whether the work involves lime mortars, timber frame repairs, stonework, roofing, or internal reconfiguration, we focus on projects where our experience genuinely adds value.
Yes. We have decades of experience with full‑scale renovations, structural alterations, timber repairs, underpinning, roof structure replacements and complex rebuilds. We are comfortable working on buildings with historic fabric, irregular geometry, failing structures or moisture‑related issues, and we approach each challenge with careful planning and precision.
Where appropriate, yes. We work with lime mortars, lime plaster, traditional timber techniques, natural stone, handmade bricks, breathable insulation systems, heritage roofing materials and conservation‑approved repair methods. These materials ensure the building performs as it should, particularly in older or listed structures where moisture management and breathability are essential.
Yes. We work cleanly, respectfully and with minimal disruption. Many of our projects take place in lived‑in period homes, estate properties or buildings with fragile historic features. We protect original fabric, manage dust and noise carefully, and maintain a tidy, organised site throughout.
Simply send us an enquiry or call with a brief outline of your project, including the building type, location, grade (if listed), and any drawings or surveys. We’ll review it, confirm whether it’s a good fit for our skills and availability, and arrange a conversation or site visit if appropriate. After initial contact, we prefer to continue communication by telephone for efficiency, but we can adjust to your circumstances.
