A listed building extension isn’t prohibited. It’s assessed. The conservation officer asks one question: does the addition harm what makes the building significant?
The schemes that get consent attach to the least significant part of the building, stay subordinate in scale, and are reversible. A contemporary extension is often the easier argument: modern work reads as new work, and most conservation officers prefer that to pastiche.
Most listed building renovation solves the same problem: the building has to work as a modern home, and what makes it worth protecting has to survive that.
So we start with what carries significance, because that’s what tells you where you have room. Later partitions and bad previous work give more latitude than owners expect. Historic fabric gets repaired properly, not replaced.
Stables, coach houses and outbuildings that have lost their purpose are usually the most underused part of a site. Bringing one back into use as habitable space is a conversion as much as a renovation, and consent rests on the building having an active future rather than a slow decline.
Agricultural barns follow a different policy route and sit with our rural conversions service.
Work that affects the character of a listed building needs Listed Building Consent, and most schemes need planning permission as well. The two are separate applications with different tests, and they are usually best submitted together so the authority assesses one coherent proposal rather than two partial ones.
Consent decisions turn on evidence. An application that explains what is significant about the building, what effect the proposal has on it and why that effect is acceptable is a different document from one that simply shows what is being built. Preparing that argument properly is the difference between a straightforward determination and a refusal.
If you want the regulations explained in detail before you speak to anyone, our Listed Building Consent guide covers what needs consent, what does not, and how retrospective applications are handled.
At Barrow House, a Grade II-listed former stable was carefully restored and reimagined as a contemporary home, retaining its original footprint, historic masonry and clock-tower remnants as the basis for the design. Sensitive interventions, including a glazed gable bringing light deep into the plan and restrained new openings, enhance functionality while preserving the building’s rhythm and character, resulting in a refined modern home that respects its heritage.
Primrose Bank is a five-bedroom residence in the highly sought-after village of Hoar Cross, set within a private position surrounded by mature woodland and open countryside. The design approach focused on retaining elements of the original building while introducing contemporary architectural forms and materials, creating a clear distinction between old and new.
This project involves a carefully considered residential extension within a Melbourne conservation area, designed to respect and enhance the character of its historic context. The proposal balances contemporary living requirements with sensitive architectural detailing to ensure a seamless and sympathetic addition.
You own, or are buying, a listed building or a home in a conservation area
You want to extend, alter, restore or fully renovate a historic property
Your building is locally listed or identified as a non-designated heritage asset
Your proposal affects the setting of a listed building or historic landscape
Your historic property sits within the Green Belt or open countryside
You already hold consent and need technical drawings or conditions discharged
Historic properties in the Green Belt carry an additional layer of policy on top of heritage designation. Our Green Belt guide explains what is currently allowed.

Most people come to us wanting someone who can design the scheme and prepare the consent application to a standard the conservation officer will accept. That is the service we provide. Where a project requires an accredited conservation professional, a structural engineer with historic buildings experience or a specialist heritage consultant, we bring them into the team and coordinate their input.
Often, yes. A listing covers the interior as well as the exterior, so removing a partition, altering a staircase, changing joinery or opening up a fireplace can all require consent even though none of it is visible from outside. Redecoration and like-for-like repair usually do not. The test is whether the work affects the character of the building as a building of special interest, and it is worth checking before work starts rather than after.
Usually. They are separate applications judged against different tests, and one does not substitute for the other. Extensions, outbuildings and most external changes need both. We prepare and submit them together so the authority is assessing a single coherent proposal.
Yes, subject to consent. Grade II listing does not prevent extension. What matters is where the extension attaches, how large it is relative to the original building, what it is built from and how convincingly the case is made that the significance of the building is not harmed. Extensions to later or less significant parts of a property are considerably easier to argue than additions to the historic core.
Yes, and a contemporary approach is frequently better received than a historic imitation. National policy and most conservation officers prefer new work that is honestly of its own time and clearly distinguishable from the original, because it keeps the history of the building readable. The requirement is quality and restraint in the detailing, not the use of period materials.
A Heritage Statement sets out what is significant about the building and its setting, and assesses the effect the proposal would have on that significance. Any application affecting a designated heritage asset needs one, and its depth should be proportionate to the importance of the building and the scale of the work. We coordinate its preparation through a specialist heritage consultant and make sure the design and the statement say the same thing.
It is a building or structure identified by the local authority as locally important, often through a local list, without being nationally listed. Listed Building Consent does not apply, but the significance of the asset is a material consideration in any planning decision affecting it, so the application still needs to address it properly.
This is more common than people expect and it is usually resolvable. The options are typically a retrospective application to regularise the work, a proposal that addresses the unauthorised alterations as part of a wider scheme, or reversal where the work has caused harm. It is worth dealing with, because unresolved unauthorised work will surface during a sale and can complicate any future application.
Fees depend on the scale and complexity of the work, the surveys the building needs and how many specialist consultants have to be involved, so there is no single figure that would be honest. What we can do at the first conversation is give you a clear view of the stages your project needs, which of them we would carry out and what a realistic fee range looks like for a project of that type, before you commit to anything.
Excellent service received from Tom and the team who helped us draft and re-draft drawings for a grade 2 listed property in Manchester City Centre. They made a complex project feel easier and helped us at every turn. Thank you!
