Restoring, renovating and extending England's listed homes
Few projects demand more care than a listed home. Our architects specialise in Grade I and Grade II listed buildings — securing listed-building consent, working with conservation officers and Historic England, and integrating modern living into historic fabric without compromising its character. Heritage architecture, interior design and construction are coordinated under one roof, so consents, restoration and modern services move as one. From full listed building restoration to the careful renovation of a period property — a country house, a Georgian townhouse, a farmhouse and its outbuildings — the same studio carries the project from consent through specialist trades to the finished interior. For country houses specifically, see our country house architects page; the interiors of such houses are a discipline of their own — see country house interior design.

Common Questions
Listed Building & Heritage Architects, answered
What can and cannot be changed in a listed building?
Listing protects the whole building, inside and out, so almost any material alteration — from removing a chimneypiece to changing windows — needs listed-building consent. In practice a great deal is still possible; we establish early what is feasible, then design changes that respect the historic fabric and are likely to secure consent.
How long does listed-building consent take?
A straightforward listed-building consent application typically takes around eight to twelve weeks once submitted. Pre-application discussions, surveys and more complex or Grade I cases can extend that, so we build a realistic consent period into the programme from the outset.
What is the difference between Grade I and Grade II for owners?
Grade II covers the majority of listed homes and protects buildings of special interest; Grade II* and Grade I mark exceptional importance and attract closer scrutiny. The higher the grade, the more sensitive the approach — but all grades require listed-building consent for alterations.
Do you work with conservation officers and Historic England?
Yes. We engage the local authority conservation officer early and, where a building's grade or significance requires it, Historic England — presenting proposals that show how the home's character is preserved. Early dialogue is the surest route to consent.
Can you handle the interiors and building work as well as the architecture?
Yes. Heritage architecture, interior design and construction are delivered under one roof, so listed-building consent, specialist restoration trades and discreetly integrated modern services are coordinated as a single programme.
Can you renovate a listed building?
Yes — renovation is where most listed projects live. Kitchens, bathrooms, services, insulation and layout can almost always be improved; the craft is achieving it within listed-building consent. We design the renovation and secure the consents as one process, so ambition and approval are never negotiated apart.
What does listed building restoration involve?
Restoration returns historic fabric to its best self — repairing rather than replacing, matching original materials and techniques, and drawing on specialist heritage trades. Much of our restoration work is on period country houses and their outbuildings, from Grade I manors to farmhouses, where restoration and discreet modernisation proceed together.
Do you take on whole country house restorations?
Yes. Country house restoration and renovation — often listed, often with land and outbuildings — is central to our work, from a Grade I-listed Oxfordshire manor to a farmhouse and stables reinvented as one home.
Planning work to a listed or period home?
Whether you are restoring, extending or buying a listed building, we would be glad to discuss how we can help — sensitively, and within the consents.
