Planning Drawings in South Wimbledon SW19

Fixed-fee, MCIAT-chartered planning drawings for South Wimbledon (SW19) homeowners — London Borough of Merton validation and local constraints handled from the start.

South Wimbledon (SW19) is one of Merton's densest Victorian and Edwardian terraced neighbourhoods, and side-return, rear and loft projects are the everyday work here. Because the houses repeat the same footprint street after street, Merton's design expectations for extensions are well understood — meeting them first time is straightforward when the drawings follow the borough's residential extension guidance.

The South Park Gardens and Pelham Road conservation areas sit within otherwise ordinary terraced streets, so whether a house falls inside one of those boundaries changes how dormers, front elevations and materials are assessed. We check a South Wimbledon property against the boundary before recommending a permitted-development or full-application route.

Article 4: London Borough of Merton does not publish its Article 4 directions to the national planning register, so permitted development rights in South Wimbledon (SW19) can’t be confirmed from open data alone — we check the direction schedule with the council before recommending a route, as part of the fixed fee.

Planning in South Wimbledon (SW19): what to know before you apply

SW19 carries no published householder Article 4 direction in South Wimbledon, so many terraces retain permitted development rights for rear and loft work — but the South Park Gardens and Pelham Road conservation areas are the exceptions, and shallow rear gardens constrain extension depth on several streets.

Planning Drawings for South Wimbledon (SW19) homes: the package and the process

Every planning drawings we prepare for an South Wimbledon property is drawn to London Borough of Merton’s validation standards and tuned to the SW19 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

Planning drawings are the scale drawings a London council uses to judge your application: existing and proposed floor plans, elevations, sections and site plans that show the design, scale and neighbour impact of your project. DrawingsDirect produces complete, validation-ready planning drawing sets for extensions, lofts and conversions across London.

What is included in a planning drawing set?

A council will only validate an application that contains the right drawings at the right scale. Our standard planning set covers everything a London validation team expects.

Site location plan (1:1250) and block plan (1:500)
Existing floor plans, elevations and sections
Proposed floor plans, elevations and sections
Roof plans where relevant, with heights and materials annotated
A design and access or heritage statement where the borough requires one

How are planning drawings different from building regulations drawings?

Planning drawings show what the building will look like and how it sits in its context. Building regulations drawings show how it will be built safely — structure, insulation, fire escape and drainage. Most projects need both; our Complete package covers the two together with structural calculations coordinated in-house.

FAQ

Planning Drawings in South Wimbledon SW19 — FAQs

What scale should London planning drawings be?+

Site location plans are 1:1250, block plans 1:500, and floor plans, elevations and sections are typically 1:100 or 1:50. We format every drawing to your specific borough's requirements.

Do I need an architect to produce planning drawings?+

No. MCIAT-chartered architectural technologists produce the same council-accepted planning drawings with the same professional accountability, and councils assess the drawings, not the author's job title.

How many revisions are included in the fee?+

All of them. The fee is fixed and we redraw free until your council approves — revisions requested by a planning officer never cost you extra.

Can you draw from my existing plans?+

We can work from existing measured drawings, but for accuracy we usually carry out a laser survey so the proposed set matches your property exactly.

Do planning drawings guarantee approval?+

No drawing can guarantee a decision, but drawing to the local plan and validation checklist maximises your odds — and we redraw free until approval.

Do I need planning permission for an extension in Merton?+

The interwar semis of Raynes Park and Morden often keep permitted development rights for rear extensions and lofts, so a full application isn't always needed. Conservation areas such as Wimbledon Village, Wimbledon Common and the John Innes estate at Merton Park restrict this. We check your street's designation first and can confirm permitted development with a Lawful Development Certificate.

What is special about building at the John Innes estate in Merton Park?+

The John Innes estate is a planned Arts-and-Crafts conservation area with a distinctive character the council protects closely — materials, proportions and rooflines are all controlled. Permitted development is often restricted there, so we design to the estate's character and prepare a full, context-led application, which is the reliable route to approval.

What do Merton's HMO Article 4 directions affect?+

In designated wards, an Article 4 direction removes permitted development for change of use to an HMO (C3 to C4), so a conversion to a house in multiple occupation needs a full application there. It doesn't affect a standard family extension, but if you are considering an HMO we confirm whether the direction covers your address and use before advising.

How long does Merton Council take to decide?+

Merton determines most householder applications within the statutory eight-week period once validated; Wimbledon and Merton Park conservation cases can involve additional consultation. We prepare submissions to the council's validation checklist to avoid the drawing queries that cause most delays.

How much do planning drawings cost in Merton?+

We agree a fixed fee before starting, typically around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Merton approves. A suburban Raynes Park extension and a Wimbledon Village or Merton Park application differ in the evidence required, so we quote once we understand your address and project rather than by the hour.
