Drawings for a whole new home — an infill plot, a backland site or a house replaced with something better on your Mole Valley 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.
Mole Valley District Council granted 83% of the householder planning decisions it made in its latest published year — 4 points below the 87% England-wide householder average. Metropolitan Green Belt covers the bulk of the district and the adopted plan releases well under one per cent of it, so countryside development is tightly controlled, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910), interwar (1918–1939) 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. Mole Valley carries at least one Article 4 direction, and conservation areas including Dorking, Leatherhead and Brockham remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Mole Valley is determined against an 8-week statutory target.
Dorking (a historic market town with a Victorian and Edwardian core, a conservation area and an Article 4 direction), Leatherhead (a market town of mixed period and postwar housing with a conservation area and an Article 4 direction), Great Bookham (an affluent commuter village with its own conservation-area character), Fetcham (largely interwar and postwar suburban semis and detached houses near Leatherhead), Brockham (a green-belt village around a classic green with a conservation area and an Article 4 direction) and Westhumble (a small Surrey Hills village of detached rural stock below Box Hill) — these are the Mole Valley pockets our drawings cover most. Heritage designations here include Dorking, Leatherhead, Brockham, Great Bookham and Little Bookham. Mole Valley District Council weighs each proposal against the Mole Valley Local Plan 2020–2039 (adopted October 2024), where the Surrey Hills National Landscape (AONB) covers much of the south and west around Dorking and Box Hill, where landscape scrutiny is heightened. Converted flats appear around Dorking and Leatherhead town centres, 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 hipped roofs on the interwar suburban semis, over Victorian and Edwardian terraces and villas in the market towns of Dorking and Leatherhead, interwar and postwar suburban semis and detached houses around the towns, substantial detached housing and period cottages in the green-belt and Surrey Hills villages and larger rural country properties to the south and west.
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 Mole Valley 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 terraces and villas in the market towns of Dorking and Leatherhead, interwar and postwar suburban semis and detached houses around the towns, substantial detached housing and period cottages in the green-belt and Surrey Hills villages and larger rural country properties to the south and west that set the local grain also set the bar the new home is judged against, because Mole Valley 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. Metropolitan Green Belt covers the bulk of the district and the adopted plan releases well under one per cent of it, so countryside development is tightly controlled, 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 — Dorking, Leatherhead, Brockham, Great Bookham and Little Bookham among Mole Valley'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. Mole Valley has Article 4 directions removing permitted-development rights in the Dorking, Leatherhead and Brockham conservation areas, so that features contributing to their character cannot be altered without consent. We resolve the design approach against the setting before the application is drawn.

Yes — a new dwelling always needs a full planning application to Mole Valley 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 Mole Valley District Council.
Below is Mole Valley District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Mole Valley grants a lower share of applications than the national average, with near-total Green Belt coverage and the Surrey Hills AONB the constraints behind most refusals of larger schemes. 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. Mole Valley 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 Dorking, Leatherhead and Great Bookham 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.
The Surrey Hills National Landscape (AONB) covers much of the south and west around Dorking and Box Hill, where landscape scrutiny is heightened. We often recommend testing the principle first — a pre-application enquiry to Mole Valley 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 Mole Valley 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 Mole Valley neighbourhoods where new-build sites come up most often:
New build drawings for a plot around Dorking's a historic market town with a Victorian and Edwardian core, a conservation area and an Article 4 direction — designed to sit in the street and drawn for Mole Valley District Council's full planning process.
New build drawings for a plot around Leatherhead's a market town of mixed period and postwar housing with a conservation area and an Article 4 direction — designed to sit in the street and drawn for Mole Valley District Council's full planning process.
New build drawings for a plot around Great Bookham's an affluent commuter village with its own conservation-area character — designed to sit in the street and drawn for Mole Valley District Council's full planning process.
New build drawings for a plot around Fetcham's largely interwar and postwar suburban semis and detached houses near Leatherhead — designed to sit in the street and drawn for Mole Valley District Council's full planning process.
New build drawings for a plot around Brockham's a green-belt village around a classic green with a conservation area and an Article 4 direction — designed to sit in the street and drawn for Mole Valley District Council's full planning process.
New build drawings for a plot around Westhumble's a small Surrey Hills village of detached rural stock below Box Hill — designed to sit in the street and drawn for Mole Valley 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 Dorking and Leatherhead, green belt or a flood zone — Mole Valley 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 Mole Valley plot and what you want to build. We check Mole Valley 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 Mole Valley 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 Mole Valley 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 Mole Valley 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 Mole Valley local plan before you spend on a full scheme.
It depends less on raw size than on whether the plot meets Mole Valley 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 Mole Valley 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 Mole Valley benefit from or require one. It is where the planning case is argued, so Mole Valley 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 Mole Valley we often recommend a pre-application enquiry to Mole Valley 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 — Mole Valley District Council will not simply wave through something much larger. On a plot near a conservation area such as Dorking and Leatherhead the design is scrutinised more closely. We test the replacement's likely scale before designing.
We price each Mole Valley 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 Mole Valley District Council approves.
