Listed building consent drawings for Southwark — measured as existing, proposed in the same detail, and supported by a heritage statement that answers Southwark Council's conservation officer on the terms the 1990 Act actually sets.
Southwark Council granted 89% of the householder planning decisions it made in its latest published year — 2 points above the 87% England-wide householder average. Mansards and roof extensions on terraces are assessed against the established roofline and the conservation-area appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), Victorian (1837–1901) and postwar (1945–1970) housing stock sets the design brief on most streets.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. Southwark carries at least one Article 4 direction, and conservation areas including Camberwell Grove, Dulwich Village and Bermondsey Street remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Southwark is determined against an 8-week statutory target.
Camberwell (Georgian and Victorian terraces around Camberwell Grove), Dulwich (villas and the Dulwich Village conservation area under the Dulwich Estate), Bermondsey (warehouse conversions and terraces off Bermondsey Street), Peckham (Victorian terraces including the Holly Grove enclave), Nunhead (modest Victorian terraces near Nunhead Green and the cemetery) and Walworth (dense Georgian and Victorian terraces threaded through large estates) — these are the Southwark pockets our drawings cover most. Heritage designations here include Camberwell Grove, Dulwich Village, Bermondsey Street, Holly Grove and Nunhead Green. Southwark Council weighs each proposal against the Southwark Plan and the borough's Residential Design Standards SPD, where the borough runs detailed basement and residential design standards on top of the usual tests. Camberwell, Peckham and the warehouse quarters around Bermondsey are heavily subdivided into flats, none of which hold householder permitted-development rights.. On roofs the borough is butterfly and parapet roofs on the terraces and flat and pitched roofs on the former warehouses, over Georgian and Victorian terraces, former warehouse and industrial conversions and Dulwich villas and postwar estates.
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.
Southwark sits within an area of Georgian and Victorian terraces, former warehouse and industrial conversions and Dulwich villas and postwar estates, and its designated heritage includes Camberwell Grove, Dulwich Village, Bermondsey Street, Holly Grove and Nunhead Green. 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 Southwark 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 Southwark 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 Southwark Council's real decision record, drawn from official planning statistics and refreshed as new data lands. Southwark grants most householder applications, but heavy conservation-area coverage, its basement policies and the Dulwich Estate's scheme of management dictate what is achievable in many neighbourhoods. Listed applications are decided on the quality of the record and the justification, which is where most refusals actually originate.

Across Camberwell, Dulwich and Bermondsey, 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.
Mansards and roof extensions on terraces are assessed against the established roofline and the conservation-area appraisal. 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 Southwark. A few of the areas where heritage work comes up most often:
Listed building consent drawings for Camberwell — Georgian and Victorian terraces around Camberwell Grove — surveyed as existing and drawn to the detail Southwark Council's conservation officer needs.
Listed building consent drawings for Dulwich — villas and the Dulwich Village conservation area under the Dulwich Estate — surveyed as existing and drawn to the detail Southwark Council's conservation officer needs.
Listed building consent drawings for Bermondsey — warehouse conversions and terraces off Bermondsey Street — surveyed as existing and drawn to the detail Southwark Council's conservation officer needs.
Listed building consent drawings for Peckham — Victorian terraces including the Holly Grove enclave — surveyed as existing and drawn to the detail Southwark Council's conservation officer needs.
Listed building consent drawings for Nunhead — modest Victorian terraces near Nunhead Green and the cemetery — surveyed as existing and drawn to the detail Southwark Council's conservation officer needs.
Listed building consent drawings for Walworth — dense Georgian and Victorian terraces threaded through large estates — surveyed as existing and drawn to the detail Southwark 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 Southwark 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 Southwark 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 Southwark 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. Southwark 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 Southwark address specifically. Southwark 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 Southwark 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 Camberwell Grove and Dulwich Village. This applies to your Southwark address specifically. Southwark 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 Southwark address specifically. Southwark Council is the decision-maker.
