Listed building consent drawings for Heigham — measured as existing, proposed in the same detail, and supported by a heritage statement that answers Norwich City Council's conservation officer on the terms the 1990 Act actually sets.
Norwich City Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. The intact Victorian terrace and villa frontages of Heigham Grove govern how far dormers, rooflights and porches can be altered, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and Edwardian (1901–1910) 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. In conservation areas such as Heigham Grove, Unthank & Christchurch and St Matthews those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Heigham is determined against an 8-week statutory target.
Heigham Grove (grid of Victorian villas and terraces at the conservation-area core), Dereham Road (long Victorian terraces running west out of the city), Nelson Street (compact two-storey terraces near the river and city edge), Avenue Road (wider Victorian houses linking Heigham to the Golden Triangle), Old Palace Road (Edwardian terraces close to the river Wensum) and Merton Road (bay-fronted terraces typical of the Christchurch streets) — these are the Heigham pockets our drawings cover most. Heritage designations here include Heigham Grove, Unthank & Christchurch and St Matthews. Norwich City Council weighs each proposal against the Greater Norwich Local Plan and the Norwich Development Management Policies, where loss of family houses to further flat and HMO conversion is regularly the deciding issue in this university-adjacent area. Large parts of Heigham are already converted into flats, maisonettes and student lets, which hold no householder permitted-development rights.. On roofs the borough is pitched and gabled slate roofs on the terraces and steep tiled and pantiled roofs on the villas, over Victorian and Edwardian terraces, larger villas around Heigham Grove and Christchurch Road and converted flats and student houses.
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.
Heigham sits within an area of Victorian and Edwardian terraces, larger villas around Heigham Grove and Christchurch Road and converted flats and student houses, and its designated heritage includes Heigham Grove, Unthank & Christchurch and St Matthews. 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 Norwich City 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 Norwich City 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 Norwich City Council's real decision record, drawn from official planning statistics and refreshed as new data lands. Norwich consents around 93% of applications, yet in Heigham & Christchurch the preserved Victorian frontages and the pressure on remaining family houses shape most conditions and refusals. Listed applications are decided on the quality of the record and the justification, which is where most refusals actually originate.

Across Heigham Grove, Dereham Road and Nelson Street, 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 intact Victorian terrace and villa frontages of Heigham Grove govern how far dormers, rooflights and porches can be altered. 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 Heigham. A few of the areas where heritage work comes up most often:
Listed building consent drawings for Heigham Grove — grid of Victorian villas and terraces at the conservation-area core — surveyed as existing and drawn to the detail Norwich City Council's conservation officer needs.
Listed building consent drawings for Dereham Road — long Victorian terraces running west out of the city — surveyed as existing and drawn to the detail Norwich City Council's conservation officer needs.
Listed building consent drawings for Nelson Street — compact two-storey terraces near the river and city edge — surveyed as existing and drawn to the detail Norwich City Council's conservation officer needs.
Listed building consent drawings for Avenue Road — wider Victorian houses linking Heigham to the Golden Triangle — surveyed as existing and drawn to the detail Norwich City Council's conservation officer needs.
Listed building consent drawings for Old Palace Road — Edwardian terraces close to the river Wensum — surveyed as existing and drawn to the detail Norwich City Council's conservation officer needs.
Listed building consent drawings for Merton Road — bay-fronted terraces typical of the Christchurch streets — surveyed as existing and drawn to the detail Norwich City 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 Norwich City 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 Norwich City 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 Norwich City 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. This applies to your Heigham address specifically.
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. Norwich City 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. This applies to your Heigham address specifically.
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 Heigham address specifically. Norwich City 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 Norwich City 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. This applies to your Heigham address specifically.
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 Heigham Grove and Unthank & Christchurch. Norwich City 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 Heigham address specifically. Norwich City Council is the decision-maker.
