CR2 primarily covers South Croydon in Croydon.
Decisions for CR2 are made by Croydon Council. Standard Permitted Development rules apply for most rear extensions and loft conversions on terraced and semi-detached houses, unless the property is in a conservation area, is listed, or sits under an Article 4 Direction. Article 4 in Croydon: No.
Building regs from £950. We do not charge hourly. Free site survey across all CR2 addresses.
From first call to planning decision: typically 12–14 weeks. Site survey week 1, design weeks 2–3, validation 1–2 weeks, statutory 8-week determination. Croydon Council timelines align with the national norm.
South Croydon in CR2 is characterised by the housing stock of Croydon — broadly victorian villas in upper norwood and crystal palace.

Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every CR2 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. CR2 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| CR2 | South Croydon | mixed Victorian and inter-war stock | CR2 covers South Croydon only; Croydon Council handles the drawing package. |
| SE19 | Upper Norwood / Crystal Palace | Victorian villas, Edwardian terraces | Adjoining district to CR2, also inside Croydon for drawing package purposes. |
| SE25 | South Norwood / Selhurst | Victorian terraces | Adjoining district to CR2, also inside Croydon for drawing package purposes. |
| CR0 | Croydon / Addiscombe / Shirley | Edwardian terraces, post-war flats | Adjoining district to CR2, also inside Croydon for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few CR2 streets, and each one changes what a drawing package can achieve at that address.
How designation changes a CR2 (South Croydon) drawing package: Croydon Council maintains 24 conservation areas, including Crystal Palace, Old Coulsdon, Purley. Inside any of them a CR2 (South Croydon) drawing package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Crystal Palace sets the tone for CR2 (South Croydon) casework.
Article 4 and your CR2 (South Croydon) drawing package: Croydon Council has made no borough-wide direction, so permitted development for a drawing package in CR2 (South Croydon) generally survives outside CR2 (South Croydon) conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a CR2 owner records that a drawing package was lawful.
What CR2 (South Croydon) is built from: Victorian villas in Upper Norwood and Crystal Palace; Edwardian terraces in Thornton Heath and Selhurst; 1930s semi-detached in Purley and Coulsdon; post-war in Croydon central. Large, mixed-density outer borough; permissive in outer areas; heritage controls in conservation pockets; major regeneration in central Croydon. That mix decides the drawing package route in CR2 (South Croydon) more than the postcode does, and it is what a Croydon Council case officer reads first. A householder application costs £548 paid to Croydon Council direct, with 8 weeks to a decision once validated.
