Streatham (SW16) is a long, mixed Lambeth neighbourhood that runs from the terraces off the High Road out to the interwar semis of Streatham Vale. The most consistent control is the Streatham Common conservation area, which governs roof form, materials and frontages for houses around the Common — a very different context from the standard terraces further north where side-return and loft projects follow the usual pattern.

Because the housing grain shifts from terrace to semi across the district, the right extension approach genuinely varies street to street. We establish where a Streatham property sits relative to the Common conservation area and the High Road frontage, then prepare the drawings to Lambeth's residential design and validation standards.

Planning in Streatham (SW16): what to know before you apply

SW16 has no householder Article 4 direction, so many Streatham houses retain permitted development rights — but the Streatham Common conservation area is the exception, and the interwar semis toward Streatham Vale carry different design expectations from the Victorian terraces nearer the High Road.

Typical Streatham housing stock

Victorian and Edwardian terraces on the streets off Streatham High Road, interwar semi-detached houses toward Streatham Vale and Norbury, and mansion blocks along the High Road and around the Common.

Planning Drawings for Streatham (SW16) homes: the package and the process

Every planning drawings we prepare for an Streatham property is drawn to London Borough of Lambeth’s validation standards and tuned to the SW16 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 Streatham SW16 — 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 a side-return extension in Lambeth?+
On many of Lambeth's Victorian and Edwardian terraces in Brixton, Clapham and Streatham, a single-storey side-return or rear extension can fall within permitted development, so a full application isn't always required. Conservation areas such as Clapham Common and Brixton Water Lane can restrict this. We check your street's designation first and can confirm permitted development with a Lawful Development Certificate.
My Lambeth home is a converted flat — does that change things?+
It often does. Many Lambeth houses are converted flats, so ownership, lease and party-wall considerations can matter as much as the planning route, and the freeholder's agreement is usually needed alongside planning. We resolve the ownership and shared-structure context before drawing so the scheme is deliverable, not just consentable.
What does Lambeth's HMO Article 4 direction affect?+
Lambeth applies an Article 4 direction removing permitted development rights for HMO conversions (C3 to C4) in designated parts of the borough, so a change of use to a house in multiple occupation needs a full application there. It doesn't affect a standard family extension, but we confirm whether it applies to your address and use before advising on a route.
How long does Lambeth Council take to decide?+
Lambeth determines most householder applications within the statutory eight-week period once validated. The terraced grids around Clapham and Brixton are party-wall-sensitive with well-established design expectations, so the commonest delay is a drawing query — we prepare submissions to the borough's residential extension guidance to keep them moving.
How much do planning drawings cost in Lambeth?+
We agree a fixed fee before starting, usually around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Lambeth approves. A side-return, a loft and a flat-conversion scheme differ in complexity, so we quote once we understand your street and project rather than charging by the hour.
