Planning Permission in Raynes Park SW20
Fixed-fee, MCIAT-chartered planning permission for Raynes Park (SW20) homeowners — London Borough of Merton validation and local constraints handled from the start.
Raynes Park (SW20) in Merton is a predominantly Edwardian and interwar suburb, running from the terraces around the station and Grand Drive to the semi-detached streets of West Wimbledon and Cottenham Park. The consistent interwar housing means side and rear additions and loft conversions follow a well-established pattern, and Merton's expectations for that house type are clearly documented.
The Wimbledon West conservation area toward Cottenham Park is the main designated control, governing frontages and roof changes for the houses inside its boundary. We confirm where a Raynes Park property sits relative to that boundary, and check for protected street trees, before recommending a permitted-development or full-application route and drawing to Merton's residential guidance.
Planning in Raynes Park (SW20): what to know before you apply
SW20 has no householder Article 4 direction, so many Raynes Park houses retain permitted development rights for side, rear and loft work — but the Wimbledon West conservation area toward Cottenham Park is the exception, and Tree Preservation Orders apply to street trees on several suburban roads.
Typical Raynes Park housing stock
Edwardian terraces around Raynes Park station and the Grand Drive streets, interwar semi-detached houses across West Wimbledon and Cottenham Park, and 1930s shopping parades along the main roads.

Planning Permission for Raynes Park (SW20) homes: the package and the process
Every planning permission we prepare for an Raynes Park property is drawn to London Borough of Merton’s validation standards and tuned to the SW20 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
Securing planning permission in London means navigating borough-specific design guidance, conservation areas, Article 4 directions and a validation checklist that differs from one council to the next. DrawingsDirect prepares the existing and proposed drawings your local planning authority needs, submits them through the Planning Portal, and manages the application to a decision — for a fixed fee agreed before we start.
Because we are MCIAT-chartered architectural technologists rather than a general architecture practice, you get the same council-accepted drawings and professional accountability at a typically lower fee, with structural coordination handled in-house.
Do I need planning permission for an extension in London?
Many single-storey rear extensions, loft conversions and outbuildings fall under permitted development rights and do not need a full planning application — but London's dense housing stock, conservation areas and Article 4 directions frequently withdraw those rights. Before you pay for a full application, we check your property against the current permitted development thresholds and your borough's local constraints.
Where permitted development applies, we recommend a Lawful Development Certificate instead of full planning — it is faster, cheaper and gives you a legal document confirming the work was lawful. Where a full application is genuinely required, we prepare it properly the first time.
Permitted development vs a full planning application
Permitted development lets you build within defined volumetric limits without committee review. A full householder application is assessed against the borough's local plan for scale, daylight, neighbour impact and design. We advise which route your project qualifies for and why.
Article 4 directions and conservation areas
If your home sits in a conservation area or under an Article 4 direction, permitted development rights are often removed — meaning even modest changes need consent. Each borough page lists the local directions and conservation areas we routinely design around.
How do you apply for planning permission through the London Planning Portal?
We manage the full lifecycle of your submission — survey, drawings, supporting documents and officer liaison — so you never have to decode a validation checklist yourself.
Phase 1 — existing and proposed site surveys
A laser-measured survey captures your property exactly, so existing and proposed drawings match reality millimetre for millimetre.
Phase 2 — technical drawing package
Site location plan, block plan, floor plans, elevations and sections drawn to your borough's scale and formatting requirements, with a design and access statement where needed.
Phase 3 — liaison with the planning officer
We answer the council's queries, negotiate amendments, and redraw free until the decision lands.
