Listed building consent drawings for Camden — measured as existing, proposed in the same detail, and supported by a heritage statement that answers Camden Council's conservation officer on the terms the 1990 Act actually sets.
Camden Council granted 88% of the householder planning decisions it made in its latest published year — 1 point above the 87% England-wide householder average. The council runs one of London's strictest basement regimes, capping depth and demanding a Basement Impact Assessment, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837) and Victorian (1837–1901) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Camden Council needs a full application. Camden carries at least one Article 4 direction, and conservation areas including Hampstead, Fitzroy Square and Bloomsbury remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Camden is determined against an 8-week statutory target.
Hampstead (Georgian and Victorian houses inside a tightly protected conservation area), Belsize Park (grand Victorian villas and red-brick mansion blocks), Camden Town (dense Victorian terraces around the market), Primrose Hill (pastel-painted Victorian terraces beside Regent's Park), Kentish Town (Victorian terraces and converted flats) and Bloomsbury (Georgian squares and formal terraces) — these are the Camden pockets our drawings cover most. Heritage designations here include Hampstead, Fitzroy Square, Bloomsbury, Camden Town and Primrose Hill. Camden Council weighs each proposal against Camden Local Plan and the Camden Planning Guidance (CPG) on home improvements, where mansard and roof additions in conservation areas are measured against the terrace's original roofline and rhythm. Purpose-built mansion flats and converted terraces are widespread, and flats and maisonettes carry no householder permitted-development rights.. On roofs the borough is London butterfly / valley roofs behind parapets and mansard roofs on the taller terraces, over Georgian and Victorian terraces, purpose-built mansion flats and converted period flats.
Listing protects the whole building, not the front elevation. Removing a partition, replacing a staircase balustrade, changing a floor finish, or lining a wall with insulation are all alterations to special interest, and all can require consent. That surprises owners far more often than the external rules do — and it is why the first deliverable on a listed project is an accurate record of what is there, not a proposal for what replaces it.
Camden sits within an area of Georgian and Victorian terraces, purpose-built mansion flats and converted period flats, and its designated heritage includes Hampstead, Fitzroy Square, Bloomsbury, Camden Town and Primrose Hill. Conservation-area designation and listing are different things and frequently overlap: a listed house inside a conservation area needs consent for internal work under the listing, and is judged on its contribution to the wider area under the designation. We establish both before proposing anything.
Section 16(2) of the 1990 Act requires Camden Council to have special regard to the desirability of preserving the building, its setting and any features of special architectural or historic interest. In practice that means the drawings must show what is being lost as clearly as what is being gained, and the case for the intervention must be made on heritage terms rather than on convenience.
Consent from Camden Council is required for works affecting special interest. That commonly includes:
We survey the building as existing at a level of detail that lets a conservation officer see the fabric, then draw the proposal in the same detail alongside a heritage statement — so the decision is made on evidence rather than on assumption.
Below is Camden Council's real decision record, drawn from official planning statistics and refreshed as new data lands. Camden approves the large majority of householder applications, though its basement policy and dense conservation coverage are the decisive constraints on many schemes. Listed applications are decided on the quality of the record and the justification, which is where most refusals actually originate.

Across Hampstead, Belsize Park and Camden Town, the schemes that get consent tend to be reversible, legible and honest: new work that reads as new rather than as imitation, services routed in existing chases rather than cut into original fabric, and interventions concentrated in later or lower-significance parts of the building. Rear additions in a contemporary idiom are often accepted where a pastiche extension is refused.
The council runs one of London's strictest basement regimes, capping depth and demanding a Basement Impact Assessment. Where planning permission is needed as well — for an extension, say — the two applications run in parallel and are usually determined together. We prepare them as a single coordinated set so the heritage case and the planning case do not contradict each other, which is a surprisingly common reason for a refusal on an otherwise sound scheme.
We prepare listed building consent packs across Camden. A few of the areas where heritage work comes up most often:
Listed building consent drawings for Hampstead — Georgian and Victorian houses inside a tightly protected conservation area — surveyed as existing and drawn to the detail Camden Council's conservation officer needs.
Listed building consent drawings for Belsize Park — grand Victorian villas and red-brick mansion blocks — surveyed as existing and drawn to the detail Camden Council's conservation officer needs.
Listed building consent drawings for Camden Town — dense Victorian terraces around the market — surveyed as existing and drawn to the detail Camden Council's conservation officer needs.
Listed building consent drawings for Primrose Hill — pastel-painted Victorian terraces beside Regent's Park — surveyed as existing and drawn to the detail Camden Council's conservation officer needs.
Listed building consent drawings for Kentish Town — Victorian terraces and converted flats — surveyed as existing and drawn to the detail Camden Council's conservation officer needs.
Listed building consent drawings for Bloomsbury — Georgian squares and formal terraces — surveyed as existing and drawn to the detail Camden Council's conservation officer needs.
They are separate consents with different tests, and many projects need both.
| Consent | What it covers | Fee | Consequence of proceeding without it |
|---|---|---|---|
| Listed building consent | Works affecting special interest, internal and external | None | Criminal offence under section 9 of the 1990 Act |
| Planning permission | Development — extensions, outbuildings, use changes | Payable | Enforcement action; may become immune after 10 years |
| Conservation area consent context | Demolition and character in a designated area | Varies | Enforcement; prosecution for unauthorised demolition |
| Building regulations | Structure, fire, insulation, ventilation | Payable | Enforcement notice; problems on sale |

A process built around what a conservation officer actually assesses.
Send us the address and the listing entry. We confirm grade, what the listing covers, whether curtilage structures are caught, and how Camden Council has treated comparable schemes.
We survey as existing in real detail — plans, elevations, sections and the features that carry the significance — because a proposal cannot be assessed against a record that does not exist.
We draw the proposal in matching detail and write the heritage statement that identifies significance, impact and justification in the terms section 16(2) requires.
We submit to Camden Council, engage with the conservation officer, and revise the drawings free until the decision is issued.
Frequently, yes. Listing covers the whole building, so removing a partition, altering a staircase, replacing joinery or re-plastering historic surfaces can all require consent from Camden Council. There is no internal exemption and no size threshold. The safe route is to establish what is significant before work is designed, which is what the measured survey is for.
Carrying out unauthorised works to a listed building is a criminal offence under section 9 of the Planning (Listed Buildings and Conservation Areas) Act 1990, and it does not become lawful with the passage of time the way some planning breaches do. Camden Council can require reinstatement. Where work has already happened, an application for retrospective consent is usually the right first step, and we can advise on it.
No. Listed building consent applications carry no application fee, which sometimes leads owners to assume the process is lighter than a planning application. It is not — the evidence expected is greater, because the decision rests on the effect on special interest rather than on amenity, and an under-documented submission is the most common cause of delay. This applies to your Camden address specifically. Camden Council is the decision-maker.
If the work is also development — an extension, an outbuilding, a change of use — then yes, and the two applications run in parallel to Camden Council. Internal alterations usually need only listed building consent. Where both are required we prepare them as one coordinated set, because inconsistencies between the two submissions are a recurring reason for delay.
Sometimes, but rarely with modern units. Historic windows are often the single most significant surviving feature, and replacement is judged on the condition of the existing joinery and the accuracy of what replaces it — glazing bar profile, glass type, opening method and reveal depth all matter. Repair and secondary glazing are usually the route that gains consent, particularly inside designated areas such as Hampstead and Fitzroy Square. This applies to your Camden address specifically. Camden Council is the decision-maker.
The statutory target is eight weeks from validation for most applications, and thirteen for larger schemes. In practice the timetable is set by how complete the submission is: a conservation officer who has to ask what the existing fabric looks like will take longer than one who can see it. We submit a record that answers those questions upfront. This applies to your Camden address specifically. Camden Council is the decision-maker.
