Drawings for a whole new home — an infill plot, a backland site or a house replaced with something better on your Sevenoaks land, taken from feasibility through a full planning application with its design and access statement to the building-regs set, coordinated as one package and revised free until approved, with a free plot check first.
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.
A new-build application is a different animal from an extension: you are not adapting a house, you are proposing a building where none stands. Across Sevenoaks the opportunities sit in the gaps — an infill plot between two houses, a backland site behind a garden, a large corner or driveway, or a tired bungalow worth replacing with a full house. The 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 that set the local grain also set the bar the new home is judged against, because Sevenoaks District Council weighs whether the design belongs on the street.
The drawings have to make the planning case and the buildable case at once. A scaled site plan fixes the footprint, the boundaries, the parking and the amenity space; the floor plans and elevations show a house that works and reads well; and the design and access statement argues the scheme against the local plan — its scale, its massing, its relationship to the neighbours' daylight and privacy. 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, precisely the kind of policy a new-build design has to satisfy from the first sketch.
Where a plot sits in or beside a conservation area — Sevenoaks High Street, The Vine, Sevenoaks Weald, Hartslands, Westerham and Kemsing among Sevenoaks's — the new house is judged on how it preserves or enhances the character of the place, and a contemporary or a contextual design each has to be justified. 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 resolve the design approach against the setting before the application is drawn.

Yes — a new dwelling always needs a full planning application to Sevenoaks District Council. The design has to answer these questions before it is likely to be approved:
We take the plot from a free feasibility check through the full planning application — site plan, floor plans, elevations and design and access statement — to the building-regs and structural set, coordinating the whole thing so the house that gets permission is the same house that gets built and signed off by Sevenoaks District Council.
Below is Sevenoaks District Council's real householder 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. A new dwelling is a full application judged on design quality — a scheme presented with a proper site plan and design and access statement is far more likely to land than a bare set of elevations.

A new-build permission is won on the argument that the plot can take another house and that the design earns its place. Sevenoaks District Council's officers weigh the principle of development on the site, the scale and massing against the neighbours, the daylight and privacy impact, the parking and drainage, and the quality of the design itself. Across Sevenoaks, Westerham and Kemsing these are the tests that separate a plot that gets developed from one that stays a garden — and the design and access statement is where the case is made.
Over half the district lies within the Kent Downs or High Weald National Landscapes (AONBs), where landscape protection shapes design and siting. We often recommend testing the principle first — a pre-application enquiry to Sevenoaks District Council, or an outline application to fix the acceptability of a new home before the full design spend — then take the approved principle through to a detailed permission and the building-regs set, so a Sevenoaks plot is de-risked before the money goes in.

We design new dwellings on the infill, backland and replacement plots across the borough. A few of the Sevenoaks neighbourhoods where new-build sites come up most often:
New build drawings for a plot around Sevenoaks's the historic market-town core around the High Street and The Vine, with a Georgian and Victorian townscape — designed to sit in the street and drawn for Sevenoaks District Council's full planning process.
New build drawings for a plot around Westerham's a historic market town with a conservation-area centre — designed to sit in the street and drawn for Sevenoaks District Council's full planning process.
New build drawings for a plot around Kemsing's a downland village where front gardens and boundaries are controlled by an Article 4 direction — designed to sit in the street and drawn for Sevenoaks District Council's full planning process.
New build drawings for a plot around Otford's a historic green-belt village of vernacular cottages around the pond — designed to sit in the street and drawn for Sevenoaks District Council's full planning process.
New build drawings for a plot around Edenbridge's a small town on the district's southern High Weald edge — designed to sit in the street and drawn for Sevenoaks District Council's full planning process.
New build drawings for a plot around Swanley's a denser, more suburban postwar settlement to the north — designed to sit in the street and drawn for Sevenoaks District Council's full planning process.
A new dwelling is judged as a building in its own right. This is what the set has to include and what each part is judged on.
| Document | What it shows | Judged on | Stage |
|---|---|---|---|
| Site plan | Footprint, boundaries, parking and amenity space | Whether the plot can take the house | Planning |
| Plans & elevations | The house that will be built | Design quality and how it sits in the street | Planning |
| Design & access statement | The argument against the local plan | Scale, massing, daylight and character | Planning |
| Structural & regs set | Construction, drainage and structure | Buildability and compliance | Building control |
On a plot in a conservation area — such as Sevenoaks High Street and The Vine, green belt or a flood zone — Sevenoaks District Council requires further justification before a new dwelling is acceptable.
A staged route that de-risks the plot before the full design spend — the principle first, then the detail, then the build.
Send us the Sevenoaks plot and what you want to build. We check Sevenoaks District Council's local plan, the site's designations and the likely acceptability of a new dwelling before you commit to design.
We develop a concept and, where it de-risks the plot, test it with a pre-application or outline enquiry to Sevenoaks District Council so the principle of a new home is confirmed before the detailed spend.
We produce the site plan, floor plans, elevations and design and access statement, with daylight/sunlight and drainage information where the site needs it, as a complete application.
We submit to Sevenoaks District Council, negotiate the design through determination, then produce the building-regulations and structural set and revise it free until the new home is approved and buildable.
Always. There is no permitted-development route to a brand-new dwelling, so a new house — whether on an infill plot, a backland site or as a replacement — needs a full planning application to Sevenoaks District Council. The application is judged on the principle of development on the plot and the quality of the design. We check the plot's realistic prospects against the Sevenoaks local plan before you spend on a full scheme.
It depends less on raw size than on whether the plot meets Sevenoaks District Council's standards for a new home — adequate amenity space, parking or access, privacy distances to neighbours, and a footprint that sits comfortably in the street. A garden or driveway that looks generous can still fail on overlooking or access. Our free feasibility check tests your Sevenoaks plot against these before you invest in design.
A design and access statement explains and justifies the design of the new dwelling — its scale, massing, materials and how it responds to the site and the local plan — and most new-build applications in Sevenoaks benefit from or require one. It is where the planning case is argued, so Sevenoaks District Council's officer can see the reasoning rather than infer it from drawings. We write it to answer the specific policies your plot engages.
Outline permission fixes the principle that a new home is acceptable on the plot without committing to the full design, which can de-risk a site before heavy spend; full permission settles both principle and detail in one go. For a single dwelling in Sevenoaks we often recommend a pre-application enquiry to Sevenoaks District Council first, then a full application, but on a marginal plot the outline route can protect you. We advise which fits your site.
Often yes. Replacing a tired bungalow or small house with a better dwelling is a common and viable route, but it is a full planning application judged on whether the replacement is a proportionate improvement in scale and design — Sevenoaks District Council will not simply wave through something much larger. On a plot near a conservation area such as Sevenoaks High Street and The Vine the design is scrutinised more closely. We test the replacement's likely scale before designing.
We price each Sevenoaks new build individually, because the plot, the design ambition and whether the site needs daylight, drainage or ecology support all vary enormously, and send a fixed, no-obligation quote within one working day. It covers the coordinated planning and building-regs set with free revisions until Sevenoaks District Council approves.
