MCIAT chartered architectural technologists covering Leatherhead and the wider Surrey commuter belt from our London base. Planning permission, building regulations, loft conversions, extensions and mansard roofs — fixed fees from £840, 30% below typical London architect rates.
Commuter town straddling the River Mole at the gateway to the Surrey Hills AONB.
All householder planning applications in Leatherhead are determined by Mole Valley District Council. The council follows the National Planning Policy Framework and its own adopted Local Plan, supported by area-specific design guides and Supplementary Planning Documents.
Conservation areas: Leatherhead Town, Fetcham, Great Bookham and Ashtead Village are conservation areas; the River Mole corridor is environmentally sensitive.
Policy quirks to watch: Much of Leatherhead's rural hinterland is designated Green Belt within the Surrey Hills AONB, which places a very high landscape bar on any visible extensions or new builds outside the settlement boundaries.
Typical housing in Leatherhead includes tudor and Georgian cottages in the old town, Edwardian villas around the commons, 1930s semis along the A24 corridor, and executive estates in Fetcham and Bookham. This mix drives the types of projects we most often prepare drawings for here.
Five core services — all fixed-fee, all delivered by MCIAT chartered architectural technologists, all within our 50-mile service radius.
Full planning submission: existing/proposed plans, elevations, site plan, and Design & Access Statement.
Construction-detail drawings for your builder and Building Control submission.
Rear dormer, hip-to-gable, L-shape or mansard loft conversion drawings.
Single-storey, double-storey, wrap-around and side-return extension drawings.
Full mansard conversion drawings with structural and thermal detailing.
Every drawing is signed off by a Chartered Member of the Institute of Architectural Technologists. The same quality bar that applies to our central London projects applies to our Leatherhead work.
We regularly submit to all M25 commuter-belt councils including Mole Valley District Council. We research each council's Local Plan, design guides and recent decision history before we start drawing.
Site visits, measured surveys and pre-application meetings in Leatherhead are all included in our fixed fee. No mileage charges, no hourly rates, no surprises on the invoice.
Our submissions across the 33 London boroughs and the M25 commuter belt are approved at first application 98% of the time. Saving you the council resubmission fee and weeks of delay.
Two-storey side and rear extensions on Leatherhead's 1930s semi-detached housing stock allow for a larger kitchen and dining area at ground floor and an additional bedroom and bathroom above. Mole Valley District Council generally supports subordinate extensions that maintain the original house's form and street rhythm.
Wrap-around extensions and garage conversions on the larger detached houses in Leatherhead are popular for creating open-plan family kitchens and home offices. These projects often combine planning permission, building regulations approval and structural calculations — all covered within our Complete package.
Sympathetic extensions to listed and historic homes require additional heritage input. For period properties in Leatherhead, we prepare heritage impact statements, use traditional materials and maintain the original proportions that Mole Valley District Council's conservation officer will expect to see.
Rear extensions and loft conversions on Leatherhead's post-war and New Town estates unlock significant additional living space. Many of these houses were built with low floor-to-ceiling heights, so we carry out a careful head-height survey before confirming loft-conversion feasibility.
Same fixed fees as our London work — no "commuter belt premium", no hourly surprises. Mole Valley District Council application fees are charged separately at the statutory rate.

Yes. Leatherhead is well within our 50-mile service radius from our London office. We cover all Leatherhead postcodes (KT22, KT23, KT24) for planning permission drawings, building regulations drawings, loft conversions, house extensions and mansard roofs. Leatherhead is 20 miles from central London (40 min from London Waterloo), so our team can comfortably visit for measured surveys and pre-application meetings with Mole Valley District Council.
Our fixed fees in Leatherhead match our London rates: Essentials from £840 (planning drawings only), Complete from £1,750 (planning + building regulations), Loft package from £1,225, and Mansard package from £1,575. These prices are roughly 30% below typical London architect rates for the same scope of work. Mole Valley District Council application fees are charged separately at the statutory rate (£258 for a householder planning application, £129 for a Lawful Development Certificate in 2026).
Yes, every project includes an in-person measured survey at your property in Leatherhead. Travel time from London is included in our fixed fee — you will never be charged mileage or hourly rates for site visits. We typically combine the measured survey with an initial brief discussion on site, then return for pre-submission checks if needed. For projects that require pre-application meetings at Mole Valley District Council, we attend on your behalf and include the call or meeting in the fee.
Yes. While our office is in London, our MCIAT chartered architectural technologists regularly submit to councils across the M25 commuter belt, including Mole Valley District Council. We use the Planning Portal for submissions, so the process is identical regardless of which local planning authority handles your application. We research each council's Local Plan, design guides, and recent decision history before preparing your drawings so that the scheme aligns with their current approach.
The statutory target for a householder planning application is 8 weeks from validation. Mole Valley District Council generally meets this target for straightforward applications, although conservation area or listed building consents can take longer. Pre-application advice typically takes 4–6 weeks. From initial instruction to final decision, expect 10–16 weeks for a typical residential project in Leatherhead.
