Change-of-use drawings for Sevenoaks — commercial to residential under Class MA, or a full application where the use classes do not line up — measured, drawn and evidenced for Sevenoaks District Council, with free revisions until your decision.
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.
The 2020 amendments to the Use Classes Order collapsed shops, offices, cafés, gyms and clinics into a single Class E, so movement between those uses is generally not development at all and needs no application. What still bites is the move out of Class E — most importantly into residential — and the uses that sit outside the class system altogether, such as houses in multiple occupation, pubs, takeaways and betting shops, each of which is sui generis or in its own class.
Class MA gives a prior-approval route from Class E to dwellings. Sevenoaks District Council cannot refuse it on general planning-policy grounds, but it can and does assess a defined list: transport, contamination, flooding, noise from nearby commercial premises, natural light to all habitable rooms, and the impact of losing a ground-floor service use in a designated area. The qualifying conditions are strict — two years in Class E use, three months vacant, and a floorspace cap — and evidence of those facts is part of the submission, not an afterthought.
Sevenoaks's stock 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 the buildings that come up for conversion here sit among Sevenoaks, Westerham, Kemsing and Otford — which is why the noise and amenity questions differ street by street rather than following a district-wide rule. Where the building sits in a conservation area such as Sevenoaks High Street, The Vine, Sevenoaks Weald, Hartslands, Westerham and Kemsing, the shopfront and frontage questions come back into play even on a prior-approval route. 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.
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, and over half the district lies within the Kent Downs or High Weald National Landscapes (AONBs), where landscape protection shapes design and siting. Both bear directly on a conversion: Sevenoaks District Council reads the resulting homes against the same amenity expectations it applies to new build, so the layout has to stand up as housing before the prior-approval matters are even reached.
Movement within Class E is usually not development. You will need prior approval or a full application from Sevenoaks District Council where any of these apply:
We measure the building as existing, draw the proposed layout to habitable-room and daylight standards, and assemble the qualifying evidence — use history, vacancy, floorspace — so the prior-approval clock starts on a complete submission.
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. Prior-approval applications are decided against a fixed list of matters, so a submission that answers each one directly is the one that gets through.

Across Sevenoaks, Westerham and Kemsing, the conversions that go through are the ones that treat the resulting homes as homes: every habitable room with adequate natural light, room sizes meeting the nationally described space standards, sensible refuse and cycle provision, and a considered answer on noise where the neighbouring units are still commercial. Natural light is the single most common reason a Class MA prior approval is refused, and it is a drawing problem before it is a policy problem.
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. Where the building does not qualify for Class MA — because of its use history, its floorspace or a local Article 4 direction — a full application is the honest route, and we say so at the outset rather than burning 56 days on a prior approval that was never going to be granted.
We prepare change-of-use submissions across Sevenoaks. A few of the areas where conversions come up most often:
Change of use drawings for Sevenoaks — the historic market-town core around the High Street and The Vine, with a Georgian and Victorian townscape — measured, laid out to space and daylight standards, and evidenced for Sevenoaks District Council.
Change of use drawings for Westerham — a historic market town with a conservation-area centre — measured, laid out to space and daylight standards, and evidenced for Sevenoaks District Council.
Change of use drawings for Kemsing — a downland village where front gardens and boundaries are controlled by an Article 4 direction — measured, laid out to space and daylight standards, and evidenced for Sevenoaks District Council.
Change of use drawings for Otford — a historic green-belt village of vernacular cottages around the pond — measured, laid out to space and daylight standards, and evidenced for Sevenoaks District Council.
Change of use drawings for Edenbridge — a small town on the district's southern High Weald edge — measured, laid out to space and daylight standards, and evidenced for Sevenoaks District Council.
Change of use drawings for Swanley — a denser, more suburban postwar settlement to the north — measured, laid out to space and daylight standards, and evidenced for Sevenoaks District Council.
Three routes, three different tests and three different timetables.
| Change | Route | Determination period | What Sevenoaks District Council assesses |
|---|---|---|---|
| Shop to café or office (within Class E) | Not development — no application | n/a | Nothing, unless conditions restrict use |
| Class E to dwellings | Class MA prior approval | 56 days | Transport, flooding, contamination, noise, natural light |
| Class E to dwellings, not qualifying | Full planning application | 8 weeks (13 for major) | Full policy assessment |
| House to small HMO | Class L, unless Article 4 applies | n/a or 8 weeks | Concentration, amenity, parking |
| Anything to sui generis use | Full planning application | 8 weeks | Amenity, hours, highways |
Routes from the Town and Country Planning (Use Classes) Order 1987 as amended in 2020, and the GPDO 2015, Schedule 2, Part 3, Class MA.
A process built around the qualifying evidence, not just the drawings.
Tell us the current use, how long it has run and what you want to do. We confirm the use classes, whether Class MA is available in Sevenoaks, and whether an Article 4 direction removes it.
We measure the building as existing, including window positions and floor-to-ceiling heights, because the daylight and space-standards case depends on real dimensions.
We draw the proposed layouts to space and daylight standards and assemble the use-history, vacancy and floorspace evidence Sevenoaks District Council needs to validate the submission.
We submit, track the determination period, answer officer queries and revise free until the decision is issued.
It depends on the use classes. Moving between uses inside Class E — shop, office, café, gym, clinic — is generally not development and needs no application to Sevenoaks District Council. Moving out of Class E, particularly into residential, needs either prior approval under Class MA or a full application. We establish which applies before any drawing work, because the routes have different evidence requirements.
Class MA is the permitted-development right that allows Class E commercial, business and service premises to become dwellings. Sevenoaks District Council assesses a defined list of matters — transport, contamination, flooding, noise, natural light and, in some designated areas, the loss of a ground-floor service use — and must determine within 56 days. It cannot refuse on general policy grounds, which is why it is a faster route where the building qualifies.
The building must have been in Class E use for at least two years before the application, and must have been vacant for at least three months immediately before it. There is also a floorspace cap, and the right is disapplied on certain protected land and where an Article 4 direction removes it. Evidence of use history and vacancy forms part of the submission — a bare assertion will not validate. This applies to your Sevenoaks address specifically. Sevenoaks District Council is the decision-maker.
Yes, and it is the most common reason Class MA prior approvals fail. Every habitable room must have adequate natural light, and deep commercial floorplates frequently cannot deliver it without new openings or a reduced unit count. We test it on the layout first, because discovering it after submission costs a full determination period. This applies to your Sevenoaks address specifically. Sevenoaks District Council is the decision-maker.
Almost always where the use becomes residential. A material change of use triggers requirements for fire safety and means of escape, sound insulation between units under Part E, ventilation, and thermal performance. Planning and building control are separate consents — we prepare both so the scheme that is approved is the scheme that can be built and signed off. This applies to your Sevenoaks address specifically. Sevenoaks District Council is the decision-maker.
A Class MA prior approval must be determined within 56 days of a valid submission, and the application is deemed approved if the council fails to decide in time — which makes validation completeness unusually valuable. A full application runs to the standard eight-week target, or thirteen weeks if it counts as a major development. This applies to your Sevenoaks address specifically. Sevenoaks District Council is the decision-maker.
