Purley (CR8) reaches west into Kenley and Woodcote, where William Webb laid out his garden suburb of the Webb Estate and Upper Woodcote Village between the 1900s and the 1920s on generous, tree-lined plots.

Both conservation areas — Upper Woodcote Village designated in 1973 and the Webb Estate in 1983, each extended in 2007 — protect Arts and Crafts houses, mature trees and open front gardens, so we design CR8 schemes to that grain.

Planning in Purley (CR8): what to know before you apply

CR8's Webb Estate and Upper Woodcote Village conservation areas closely control the garden-suburb character — individually designed houses, deep tree-lined plots and open front boundaries — so extensions, roof changes and boundary works are assessed against that grain even where householder permitted development survives. Croydon's borough-wide Article 4 direction still removes permitted development for small C3-to-C4 HMO conversions across the district.

Planning Drawings for Purley (CR8) homes: the package and the process

Every planning drawings we prepare for an Purley property is drawn to Croydon Council’s validation standards and tuned to the CR8 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 Purley CR8 — 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 Croydon?+
It depends where in the borough you are. The interwar semis and detached homes of Purley, Sanderstead and Coulsdon often keep fuller permitted development rights than inner-London terraces, so larger rear and single-storey extensions can qualify. Conservation areas such as Addiscombe and South Norwood, and HMO Article 4 wards, restrict this. We check your address first and can confirm permitted development with a Lawful Development Certificate.
Can I build a larger extension on a Purley or Sanderstead plot?+
Often, yes. Croydon's generous suburban plots make substantial rear and double-storey extensions viable where a tight terrace could not accommodate them. The limit is usually design and amenity policy rather than space. We design to use the plot fully within permitted-development allowances or a well-evidenced full application, checking the limits for detached and semi-detached homes first.
What do Croydon's HMO Article 4 directions mean for me?+
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 on a route.
How long does Croydon Council take to decide?+
Croydon determines most householder applications within the statutory eight-week period once validated. As a large borough spanning terraces to suburban plots, a complete, correctly scaled submission is the best way to avoid a validation query — we prepare Croydon drawings to the council's checklist to keep the application on track.
How much do planning drawings cost in Croydon?+
We quote a fixed fee upfront, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Croydon approves. Because plots here allow larger schemes, the fee tracks complexity — a single-storey rear differs from a double-storey — and we confirm it once we understand your plans.
