Listed building consent drawings for St Albans — measured as existing, proposed in the same detail, and supported by a heritage statement that answers St Albans City & District Council's conservation officer on the terms the 1990 Act actually sets.
St Albans City & District Council granted 88% of the householder planning decisions it made in its latest published year — 1 point above the 87% England-wide householder average. Over 80 per cent of the district is Metropolitan Green Belt, the dominant constraint and the reason the emerging plan must justify green-belt release, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), Victorian (1837–1901), Edwardian (1901–1910), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. St Albans carries at least one Article 4 direction, and conservation areas including St Albans city centre, Fishpool Street and St Michael's Village remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in St Albans is determined against an 8-week statutory target.
St Albans city centre (the medieval and Georgian historic core around the cathedral and Fishpool Street), Harpenden (affluent commuter town of Edwardian and interwar semis and detached houses), Marshalswick (interwar and postwar St Albans suburb of detached houses and semis), Redbourn (historic village with a large common, period cottages and modern infill), Wheathampstead (historic village between St Albans and Harpenden) and London Colney (large village with mixed twentieth-century estate housing) — these are the St Albans pockets our drawings cover most. Heritage designations here include St Albans city centre, Fishpool Street, St Michael's Village, Verulamium, Harpenden and Redbourn. St Albans City & District Council weighs each proposal against the saved 1994 St Albans District Local Plan Review, with a new Local Plan to 2041 at examination, where the historic city core carries dense conservation coverage layered over the scheduled Roman remains at Verulamium. Converted flats concentrate in the city centre and along the commuter-rail corridors, and carry no householder permitted-development rights.. On roofs the borough is pitched plain-clay-tile roofs on the historic core and hipped roofs on the interwar suburban semis, over medieval, Georgian and Victorian stock in the historic city core, Victorian and Edwardian commuter terraces, interwar and postwar suburban semis and detached houses in Marshalswick, Harpenden and the larger villages and period cottages in the green-belt villages.
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.
St Albans sits within an area of medieval, Georgian and Victorian stock in the historic city core, Victorian and Edwardian commuter terraces, interwar and postwar suburban semis and detached houses in Marshalswick, Harpenden and the larger villages and period cottages in the green-belt villages, and its designated heritage includes St Albans city centre, Fishpool Street, St Michael's Village, Verulamium, Harpenden and Redbourn. 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 St Albans City & District 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 St Albans City & District 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 St Albans City & District Council's real decision record, drawn from official planning statistics and refreshed as new data lands. St Albans grants a fair share of householder applications, with near-total green-belt coverage and the sensitivity of the historic city core the constraints behind most refusals. Listed applications are decided on the quality of the record and the justification, which is where most refusals actually originate.

Across St Albans city centre, Harpenden and Marshalswick, 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.
Over 80 per cent of the district is Metropolitan Green Belt, the dominant constraint and the reason the emerging plan must justify green-belt release. 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 St Albans. A few of the areas where heritage work comes up most often:
Listed building consent drawings for St Albans city centre — the medieval and Georgian historic core around the cathedral and Fishpool Street — surveyed as existing and drawn to the detail St Albans City & District Council's conservation officer needs.
Listed building consent drawings for Harpenden — affluent commuter town of Edwardian and interwar semis and detached houses — surveyed as existing and drawn to the detail St Albans City & District Council's conservation officer needs.
Listed building consent drawings for Marshalswick — interwar and postwar St Albans suburb of detached houses and semis — surveyed as existing and drawn to the detail St Albans City & District Council's conservation officer needs.
Listed building consent drawings for Redbourn — historic village with a large common, period cottages and modern infill — surveyed as existing and drawn to the detail St Albans City & District Council's conservation officer needs.
Listed building consent drawings for Wheathampstead — historic village between St Albans and Harpenden — surveyed as existing and drawn to the detail St Albans City & District Council's conservation officer needs.
Listed building consent drawings for London Colney — large village with mixed twentieth-century estate housing — surveyed as existing and drawn to the detail St Albans City & District 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 St Albans City & District 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 St Albans City & District 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 St Albans City & District 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. St Albans City & District 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 St Albans address specifically. St Albans City & District 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 St Albans City & District 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 St Albans city centre and Fishpool Street. St Albans City & District 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 St Albans address specifically. St Albans City & District Council is the decision-maker.
