Refused by Sevenoaks District Council? We read the decision notice, tell you honestly whether to appeal or resubmit, and prepare the drawings and statement that answer each reason for refusal on the Planning Inspectorate's terms.
Sevenoaks District Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. Around 93% of the district is Metropolitan Green Belt, one of the most green-belt-constrained districts in England, so most countryside development faces a very-special-circumstances test, 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. Sevenoaks carries at least one Article 4 direction, and conservation areas including Sevenoaks High Street, The Vine and Sevenoaks Weald remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Sevenoaks is determined against an 8-week statutory target.
Sevenoaks (the historic market-town core around the High Street and The Vine, with a Georgian and Victorian townscape), Westerham (a historic market town with a conservation-area centre), Kemsing (a downland village where front gardens and boundaries are controlled by an Article 4 direction), Otford (a historic green-belt village of vernacular cottages around the pond), Edenbridge (a small town on the district's southern High Weald edge) and Swanley (a denser, more suburban postwar settlement to the north) — these are the Sevenoaks pockets our drawings cover most. Heritage designations here include Sevenoaks High Street, The Vine, Sevenoaks Weald, Hartslands, Westerham and Kemsing. Sevenoaks District Council weighs each proposal against the Sevenoaks Core Strategy (adopted February 2011) and the Allocations and Development Management Plan (adopted February 2015), where over half the district lies within the Kent Downs or High Weald National Landscapes (AONBs), where landscape protection shapes design and siting. Converted flats and maisonettes appear around Sevenoaks town and Swanley, and none of them hold householder permitted-development rights.. On roofs the borough is dual-pitch tiled roofs on the town villas and terraces and steep tiled and hipped roofs on the vernacular village cottages, over Victorian and Edwardian villas and terraces around Sevenoaks town, interwar and postwar detached and semi-detached commuter housing, historic vernacular cottages in Kentish ragstone, weatherboarding and tile-hanging across the green-belt and AONB villages and larger country properties in the rural south.
Two routes exist and they suit different refusals. A free-go resubmission — a fresh application within twelve months of the refusal, on the same site and in the same description — costs no fee and lets you change the scheme. An appeal keeps the scheme as refused and asks an Inspector to disagree with Sevenoaks District Council. Where the refusal reasons are about design detail that can be fixed, resubmission is usually faster; where they are about principle, an appeal is the only route that resolves it.
The decision notice is the brief. Each numbered reason cites policy and states a harm, and the appeal has to meet each one with evidence — sections showing daylight, elevations showing the relationship to neighbours, a site plan proving separation distances. Assertion loses appeals. Sevenoaks is largely Victorian and Edwardian villas and terraces around Sevenoaks town, interwar and postwar detached and semi-detached commuter housing, historic vernacular cottages in Kentish ragstone, weatherboarding and tile-hanging across the green-belt and AONB villages and larger country properties in the rural south, and dual-pitch tiled roofs on the town villas and terraces and steep tiled and hipped roofs on the vernacular village cottages shape what the Inspector will accept as characteristic here.
Around 93% of the district is Metropolitan Green Belt, one of the most green-belt-constrained districts in England, so most countryside development faces a very-special-circumstances test, which frequently appears in refusal reasons and therefore has to be addressed head-on. The Kemsing conservation area Article 4 direction (adopted 2023) brings the loss or alteration of front boundary treatments and front gardens under planning control, and the district's many conservation areas such as Westerham and the Sevenoaks High Street layer further restrictions on external changes.
We give an honest read of the decision notice first. An appeal is usually the right route where:
We take each numbered reason for refusal and answer it with a drawing or an evidenced statement — not with a restatement of the original application. That is the difference between an appeal that reads as a complaint and one that reads as a case.
Below is Sevenoaks District Council's real decision record, drawn from official planning statistics and refreshed as new data lands. Sevenoaks grants a fair share of applications broadly in line with the national picture, with pervasive Green Belt and AONB coverage the defining pressure on anything beyond modest householder work. Knowing what this authority actually refuses, and why, is the starting point for deciding whether to appeal or to redesign.

Across Sevenoaks, Westerham and Kemsing, the appeals that succeed are narrow and evidenced. They show the daylight test drawn rather than described, they cite the Inspector's own decisions on comparable sites, and they concede the points that are not worth arguing so the case concentrates on the ones that are. An appeal that disputes every reason equally reads as unfocused and usually fails on the strongest one.
Over half the district lies within the Kent Downs or High Weald National Landscapes (AONBs), where landscape protection shapes design and siting. Most householder appeals are decided by written representations, with the Inspector visiting the site unaccompanied. That makes the drawings the primary evidence: what is not on the page is not in front of the Inspector. We prepare the set on that basis, and where the honest answer is that the refusal was sound, we say so and redesign instead.
We prepare appeal drawings and statements across Sevenoaks. A few of the areas where refusals come up most often:
Appeal drawings for Sevenoaks — the historic market-town core around the High Street and The Vine, with a Georgian and Victorian townscape — answering Sevenoaks District Council's reasons for refusal with evidence rather than assertion.
Appeal drawings for Westerham — a historic market town with a conservation-area centre — answering Sevenoaks District Council's reasons for refusal with evidence rather than assertion.
Appeal drawings for Kemsing — a downland village where front gardens and boundaries are controlled by an Article 4 direction — answering Sevenoaks District Council's reasons for refusal with evidence rather than assertion.
Appeal drawings for Otford — a historic green-belt village of vernacular cottages around the pond — answering Sevenoaks District Council's reasons for refusal with evidence rather than assertion.
Appeal drawings for Edenbridge — a small town on the district's southern High Weald edge — answering Sevenoaks District Council's reasons for refusal with evidence rather than assertion.
Appeal drawings for Swanley — a denser, more suburban postwar settlement to the north — answering Sevenoaks District Council's reasons for refusal with evidence rather than assertion.
Three responses to a refusal, with different costs, timescales and prospects.
| Route | Deadline | Typical timescale | Best where |
|---|---|---|---|
| Householder appeal | 12 weeks from the decision | About 8–12 weeks | The refusal turns on principle or a disputed harm |
| Section 78 appeal (other) | 6 months from the decision | Several months | Larger schemes, change of use, new dwellings |
| Free-go resubmission | 12 months from the decision | 8 weeks | The reasons are fixable design detail |
| Fresh application, redesigned | No deadline | 8 weeks | The scheme needs a different approach entirely |
Deadlines from the Town and Country Planning Act 1990, section 78, and the Planning Inspectorate's published appeal procedures.
A process built around the decision notice, because that is what the Inspector reads first.
Send us the decision notice and the refused drawings. We tell you honestly whether the reasons are appealable, whether a resubmission is faster, and how Sevenoaks District Council has fared on comparable appeals.
We gather the material that answers each reason — daylight geometry, separation distances, decided appeals on similar sites, and the relevant policies read in full rather than in extract.
We prepare the drawings the Inspector needs and a statement of case that takes each numbered reason in turn, conceding what should be conceded and evidencing the rest.
We lodge the appeal inside the deadline, respond to the council's statement, and revise free until the Inspector issues a decision.
Twelve weeks from the date on the decision notice for a householder appeal, and six months for most other section 78 appeals. The deadline is strict and the Planning Inspectorate will not accept a late appeal, so the first thing we do on a Sevenoaks refusal is check the date and work backwards from it. Sevenoaks District Council is the decision-maker.
It depends what the reasons say. If they identify design detail you are willing to change, a free-go resubmission within twelve months costs no application fee and usually resolves faster. If they refuse the principle — that an extension of this type does not belong here at all — only an appeal settles it, because a resubmission would meet the same objection. This applies to your Sevenoaks address specifically. Sevenoaks District Council is the decision-maker.
Nationally, a minority of householder appeals succeed, and the ones that do tend to be narrow, evidenced and focused on a single disputed harm. We look at how Sevenoaks District Council's refusals have fared at appeal and at comparable decisions nearby before advising, and we will tell you when we think the refusal was sound — an appeal with no prospect costs months.
The scheme itself cannot change on appeal — the Inspector determines the application as refused. What usually needs preparing is evidence: sections showing daylight, elevations showing the relationship to neighbours, and context drawings showing what already exists on the street. Those explain why the refused scheme causes no harm, without altering it. This applies to your Sevenoaks address specifically. Sevenoaks District Council is the decision-maker.
In most written-representation appeals, yes — usually unaccompanied, viewing the site from public land and neighbouring property where access is arranged. That is why the drawings matter so much: the Inspector sees the site once, briefly, and everything else comes from the paperwork you submitted. This applies to your Sevenoaks address specifically. Sevenoaks District Council is the decision-maker.
Only where the council has behaved unreasonably — refusing against its own officer's clear recommendation without evidence, or failing to substantiate a reason for refusal. Costs awards are the exception rather than the norm, and they are decided separately from the appeal itself. Where the grounds genuinely exist, we make the application alongside the appeal. This applies to your Sevenoaks address specifically. Sevenoaks District Council is the decision-maker.
We quote each Sevenoaks appeal individually after reading the decision notice, because the work depends entirely on how many reasons are in play and what evidence they demand, and send a fixed, no-obligation quote within one working day.
