Specialist renovation of Grade I, Grade II and locally listed buildings across London. Our RIBA architects and heritage consultants navigate conservation requirements, secure listed building consent and deliver restorations that honour original craftsmanship while introducing contemporary comfort — without compromising the fabric that makes your property irreplaceable.
London's listed buildings are irreplaceable. Every intervention — from rewiring a Georgian townhouse to extending a Victorian villa in a conservation area — demands an understanding of historic building fabric, traditional construction methods and the regulatory framework that protects these structures for future generations. Our heritage team brings all three.
We employ RIBA chartered architects with specific expertise in historic buildings, supported by craftsmen trained in lime plastering, timber frame repair, stone masonry, sash window restoration and lead roofing. This is not general construction applied to old buildings — it is specialist heritage work delivered by people who understand the difference between Portland and Bath stone, between haired lime plaster and modern gypsum, between a mortise-and-tenon joint and a modern bracket.
Our heritage consultants prepare heritage impact assessments, significance statements and listed building consent applications that satisfy conservation officers across every London borough. We've secured consent for projects ranging from discreet internal alterations to Grade II* properties through to full structural interventions in Hampstead Conservation Area — maintaining a 98% approval rate because we present proposals that demonstrate genuine understanding of what makes each building significant.
Whether you're restoring a neglected Regency terrace, converting a Victorian schoolhouse, or sensitively modernising a Grade I listed manor, our integrated design-and-build approach means one team handles everything: from the heritage statement through to the final coat of limewash.
From structural stabilisation of Tudor timber frames to the meticulous recreation of Edwardian decorative plasterwork — our heritage team covers every discipline required to restore, conserve and enhance London's most significant buildings.
Comprehensive restoration of Grade I, Grade II* and Grade II listed properties. We repair, conserve and reinstate original features — from structural timber repairs and stone consolidation to the recreation of lost decorative elements using historically accurate materials and techniques.
Extensions, alterations and refurbishments within London's conservation areas, designed to respect the character and appearance that earned the designation. We manage Article 4 direction restrictions, conservation officer consultations and the enhanced planning requirements that apply to these protected settings.
Comprehensive significance appraisals and heritage impact assessments that satisfy conservation officers and Historic England. We document what makes your building special, assess how proposed works will affect that significance, and present mitigation strategies that demonstrate responsible stewardship.
In-house craftsmen skilled in lime plastering, cornice repair, ceiling rose restoration, dado and picture rail reinstatement, panelling, architrave profiles and sash window overhaul. We match original moulding profiles, timber species and finishing techniques to maintain visual and historical continuity.
Historic buildings develop structural issues that require specialist understanding — bowing walls, subsidence, failed lintels, timber rot, chimney movement. Our RICS surveyors diagnose the cause before our engineers design sympathetic repairs using traditional techniques: lime stitching, needle beams, timber splicing and controlled underpinning.
Discreet integration of modern services into historic fabric — underfloor heating beneath original floorboards, concealed electrical rewiring, secondary glazing behind original sashes, mechanical ventilation through existing chimney flues. We deliver 21st-century comfort without compromising 18th or 19th-century character.
Heritage projects follow a distinct pathway — governed by listed building legislation, conservation policy and the physical demands of working with historic fabric. Here's how we manage every stage.
We begin with a thorough condition survey of the building — documenting structural movement, damp, timber decay, failed services and the condition of every heritage feature. Simultaneously, we research the building's history: its listing description, original architect (where known), construction dates, previous alterations and its significance within the local conservation area. This dual assessment forms the evidence base for all subsequent design and consent work.
Our architects develop proposals that respond directly to the building's significance. We identify which elements are sacrosanct, which can tolerate sensitive alteration and where new interventions can be introduced without harm. Design options are presented alongside impact assessments so you can see exactly how each proposal affects the heritage value of your property. For extensions or additions, we design in a language that complements without mimicking — contemporary where appropriate, traditional where the context demands it.
We prepare and submit the full listed building consent application — including a detailed heritage statement, design and access statement, and all supporting drawings. For Grade I and II* buildings, we liaise directly with Historic England as a statutory consultee. We manage pre-application meetings with conservation officers, negotiate amendments where required and ensure your application presents a compelling case for approval. Our 98% LBC success rate reflects the rigour of this preparation.
Our in-house heritage trades team carries out the physical restoration work using traditional methods and materials: lime mortar and render, hand-applied plasterwork, timber frame carpentry, lead sheet roofing, stone repair and conservation. Every intervention is reversible where possible and documented for future custodians. We maintain a detailed photographic record throughout, and our architects conduct weekly site inspections to ensure the finished work matches the consented design in every respect.
On completion, we compile a full conservation archive: before-and-after photography, material specifications, supplier details, paint colours, lime mix ratios and maintenance guidance specific to your building's construction. This document becomes an invaluable resource for future maintenance and any subsequent consent applications. We also provide a scheduled maintenance plan — because heritage buildings need ongoing care, not just one-off restoration.
Each listing grade carries different obligations and consenting requirements. Our team has direct experience with all categories.
Buildings of exceptional interest. Just 2.5% of listed buildings hold this status. All works require LBC and Historic England consultation. We've completed sensitive internal works to Grade I properties in Westminster and Camden.
Particularly important buildings of more than special interest. Around 5.8% of listed buildings. Historic England is a statutory consultee. We manage the additional scrutiny these applications attract with thorough heritage statements.
Buildings of special interest — the majority of all listed buildings. Our most common heritage project type. We secure LBC for extensions, internal alterations, window replacements, re-roofing and full refurbishments across all London boroughs.
Buildings identified by local authorities as having heritage significance but not nationally listed. While LBC isn't required, demolition and alteration trigger enhanced planning scrutiny. We present applications that respect their local importance.

Heritage renovation demands a fundamentally different approach from standard construction. Here's what sets our heritage practice apart.
Lime plasterers, stone masons, sash window joiners, lead roofers and decorative craftsmen — all employed directly, not subcontracted. This gives us control over quality, scheduling and the specialist skills that heritage work demands.
Our heritage consultants write applications that conservation officers want to approve — demonstrating deep understanding of significance, proportionate impact assessment and design solutions that genuinely enhance the building's future without harming its past.
We source lime putty from specialist kilns, reclaimed bricks from period demolitions, handmade clay tiles, traditional pigments and FSC-certified timber species that match original specifications. No modern substitutes where authenticity matters.
We maintain working relationships with conservation teams across Camden, Islington, Westminster, Barnet, Haringey and all inner London boroughs.
For Grade I and II* works, we manage the statutory consultation process with Historic England directly, streamlining what can be a lengthy approval process.
Wherever possible, we design interventions that can be reversed by future custodians — preserving options for the building's next chapter without foreclosing possibilities.
Discreet insulation strategies for solid-walled heritage buildings — breathable lime-based insulation, secondary glazing and draught-proofing that improve comfort without trapping moisture.
Full restoration of original timber sash windows — draught-sealed, weight-balanced, reputtied and reglazed. Far superior to replacement, both aesthetically and in terms of heritage compliance.
Traditional roofing materials reinstated by experienced leadworkers and slaters. We source matching Welsh slate, Westmorland slate and cast lead sheet to original gauges and profiles.
Cornice repair, ceiling rose restoration, dado rails, panel mouldings and bespoke plaster enrichments — all hand-run or cast from moulds taken from original profiles within the property.
Every heritage project concludes with a detailed archive of materials, methods, suppliers and maintenance guidance — an invaluable resource for the building's future care.

Our Georgian townhouse in Hampstead had been badly treated by previous owners. The heritage team stripped everything back with extraordinary care, rebuilt the cornicing from fragments they found in the attic, and restored every sash window. The conservation officer actually complimented the quality of the heritage statement — that never happens.
We were terrified of getting listed building consent for our kitchen extension in Canonbury. Hampstead Renovations handled the entire process — the heritage impact assessment, the meetings with Islington's conservation team, and the design itself. Approved without amendments. The builders clearly knew how to work alongside old fabric without damaging it.
The lime plasterers on this team are genuinely exceptional. They matched 200-year-old moulding profiles by hand-running new sections from templates they made on site. The level of craftsmanship is something you simply don't find with standard builders — these people understand historic buildings in a way that gives you complete confidence.
