Listed building consent drawings for Ashford — measured as existing, proposed in the same detail, and supported by a heritage statement that answers Ashford Borough Council's conservation officer on the terms the 1990 Act actually sets.
Ashford Borough Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. Ashford contains Aldington - Church Area, Aldington - Clap Hill, Appledore conservation areas (Aldington - Church Area designated 1996), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and postwar (1945–1970) housing stock sets the design brief on most streets.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. Ashford carries at least one Article 4 direction, and conservation areas including Aldington - Church Area, Aldington - Clap Hill and Appledore remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Ashford is determined against an 8-week statutory target.
Aldington - Church Area (conservation area designated in 1996), Aldington - Clap Hill (conservation area designated in 1996), Appledore (conservation area designated in 1987), Ashford - Lacton Green (conservation area designated in 1991), Bethersden (conservation area designated in 1996), Bilsington (conservation area designated in 1996), Brabourne (conservation area designated in 1996), Chilham (conservation area designated in 1996), Bircholt (ward of Ashford), Downs North (ward of Ashford), Isle of Oxney (ward of Ashford), Kennington (ward of Ashford), Saxon Shore (ward of Ashford), Tenterden South (ward of Ashford), Tenterden St Michael's (ward of Ashford) and Upper Weald (ward of Ashford) — these are the Ashford pockets our drawings cover most. Heritage designations here include Aldington - Church Area, Aldington - Clap Hill, Appledore, Ashford - Lacton Green, Bethersden, Bilsington, Brabourne and Chilham. Ashford Borough Council weighs each proposal against Ashford Borough Council's adopted local plan and its householder design guidance, where the 19,960 homes here are 21% pre-1900, 7% 1955-1964, 6% 1965-1972, which is what sets the realistic roof and rear-projection options. On roofs the borough is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building, over Victorian and earlier houses (21% of 19,960 homes), late-1950s and early-1960s houses (7%) and late-1960s and early-1970s houses (6%).
Before anything is drawn we check your address against the designations that apply in Ashford: Aldington - Church Area (conservation area designated in 1996), Aldington - Clap Hill (conservation area designated in 1996), Appledore (conservation area designated in 1987), Ashford - Lacton Green (conservation area designated in 1991), Bethersden (conservation area designated in 1996), Bilsington (conservation area designated in 1996), Brabourne (conservation area designated in 1996) and Chilham (conservation area designated in 1996). Inside those boundaries permitted development is curtailed and Ashford Borough Council assesses materials, window detail and roof form against the area's own appraisal, so a scheme that would be waved through two streets away can need a full application here.
Beyond the designated areas, Ashford takes in Bircholt, Downs North, Isle of Oxney, Kennington, Saxon Shore, Tenterden South, Tenterden St Michael's and Upper Weald. Ashford Borough Council has 73 recorded Article 4 directions — check the address before assuming PD applies in the district.
On stock, Ashford is Victorian and earlier houses (21% of 19,960 homes), late-1950s and early-1960s houses (7%) and late-1960s and early-1970s houses (6%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. Ashford Borough Council decided 453 householder applications in the latest published year and granted 92%, with 75% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Ashford runs pre-1900 3% (190 homes), 1900-1918 0% (30 homes), 1919-1929 0% (10 homes), 1930-1939 6% (350 homes), 1945-1954 3% (170 homes), 1955-1964 30% (1,850 homes), 1965-1972 33% (1,990 homes), 1973-1982 4% (260 homes), 1983-1992 5% (310 homes), 1993-1999 4% (220 homes) and 2000-2008 3% (170 homes). That distribution is why pre-1900 detailing dominates the drawings here, and it is measured from council-tax records rather than assumed from the street name.
Ashford Borough Council also decides for Bircholt, Downs North, Isle of Oxney, Kennington, Saxon Shore, Tenterden South, Tenterden St Michael's and Upper Weald, so a decision in Ashford sits inside a wider pattern of decisions we track across the same authority — useful when an officer cites a precedent from the next area over.
The Article 4 directions recorded for this council include 1 - Caravan, 2 3 - agriculture, 4 - forestry, 1 - Gate, fence, wall, 2 - Use of land, 1 - Use of land, 2 3 - Agricultural, 4 - Forestry and 1 - gate, fence, 2 - use of land. Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

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.
Ashford sits within an area of Victorian and earlier houses (21% of 19,960 homes), late-1950s and early-1960s houses (7%) and late-1960s and early-1970s houses (6%), and its designated heritage includes Aldington - Church Area, Aldington - Clap Hill, Appledore, Ashford - Lacton Green, Bethersden, Bilsington, Brabourne and Chilham. 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 Ashford Borough 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 Ashford Borough 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 Ashford Borough Council's real decision record, drawn from official planning statistics and refreshed as new data lands. Ashford Borough Council granted 92% of 453 householder decisions in the year to 31 March 2026, 75% of them inside eight weeks. Listed applications are decided on the quality of the record and the justification, which is where most refusals actually originate.

Across Aldington - Church Area, Aldington - Clap Hill and Appledore, 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.
Ashford contains Aldington - Church Area, Aldington - Clap Hill, Appledore conservation areas (Aldington - Church Area designated 1996), so materials, fenestration and roof form are assessed against the 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 Ashford. A few of the areas where heritage work comes up most often:
Listed building consent drawings for Aldington - Church Area — conservation area designated in 1996 — surveyed as existing and drawn to the detail Ashford Borough Council's conservation officer needs.
Listed building consent drawings for Aldington - Clap Hill — conservation area designated in 1996 — surveyed as existing and drawn to the detail Ashford Borough Council's conservation officer needs.
Listed building consent drawings for Appledore — conservation area designated in 1987 — surveyed as existing and drawn to the detail Ashford Borough Council's conservation officer needs.
Listed building consent drawings for Ashford - Lacton Green — conservation area designated in 1991 — surveyed as existing and drawn to the detail Ashford Borough Council's conservation officer needs.
Listed building consent drawings for Bethersden — conservation area designated in 1996 — surveyed as existing and drawn to the detail Ashford Borough Council's conservation officer needs.
Listed building consent drawings for Bilsington — conservation area designated in 1996 — surveyed as existing and drawn to the detail Ashford Borough 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 Ashford Borough 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 Ashford Borough 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 Ashford Borough 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. Ashford Borough 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 Ashford address specifically. Ashford Borough 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 Ashford Borough 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 Aldington - Church Area and Aldington - Clap Hill. This applies to your Ashford address specifically. Ashford Borough 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 Ashford address specifically. Ashford Borough Council is the decision-maker.
