Planning Drawings in Purley CR8
Fixed-fee, MCIAT-chartered planning drawings for Purley (CR8) homeowners — Croydon Council validation and local constraints handled from the start.
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.
Typical Purley housing stock
Individually designed Arts and Crafts, Tudor Revival and Neo-Georgian houses on William Webb's garden-suburb estate west of Purley town centre, set on generous tree-lined plots, with Victorian, Edwardian and interwar housing across the wider Purley and Kenley streets.

Planning Drawings for Purley (CR8) homes: the package and the process
A planning set is judged as a set, not as individual sheets. Every existing drawing needs its proposed counterpart at the same scale and orientation so the officer can read the change at a glance, each sheet needs its own number, title, scale bar and north point, and the whole package needs to survive being printed at A3 without a dimension becoming illegible.
We draw to the conventions validation teams expect: plans and elevations at 1:100 or 1:50, a location plan at 1:1250 with the site edged red, a block plan at 1:500, and sections cut where the change in level or roof form actually happens rather than where they are easiest to draw.
The drawing list itself changes with the building. A detached house needs four elevations; a mid-terrace needs two plus a section through the party walls to show what is not visible from outside. Getting that list right at the start is what stops a validation officer asking for a sheet three weeks in.
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.
How quickly can you produce planning drawings in London?
After a laser survey, a standard householder set is typically ready within 7 days. We review every drawing against your borough's validation checklist before it reaches a planner's desk, which is why our first-time approval rate sits around 96%.
| Drawing | Typical scale | What it shows |
|---|---|---|
| Site location plan | 1:1250 | The property in its street context, site edged red |
| Block plan | 1:500 | The building's footprint and position in the plot |
| Floor plans (existing & proposed) | 1:100 / 1:50 | Room layout, walls, openings and the proposed changes |
| Elevations (existing & proposed) | 1:100 / 1:50 | Each face of the building and how it changes |
| Sections | 1:100 / 1:50 | A cut through showing heights, levels and roof form |
