Chartered planning drawings prepared for Croydon Council — extensions, lofts and conversions drawn to the Croydon Local Plan 2018, from Selhurst terraces to Sanderstead avenues, delivered in days and revised free until you have a decision.
Croydon is the most populous London borough and one of the busiest planning authorities in the capital, stretching from the dense Victorian grids of Thornton Heath, Selhurst and South Norwood to the Arts-and-Crafts and Neo-Georgian villas of Purley, Sanderstead and Shirley. William Webb's garden-suburb Webb Estate sits at one extreme; the LCC-built New Addington estate at the far south-east end of the Tramlink at another. A drawing pack that satisfies a case officer in Waddon can be picked apart in Coulsdon, because Croydon reads context street by street: plot widths, building lines, roof pitch and the rhythm of the frontage all feed the judgement.
We prepare architectural drawings across Croydon every week, so we know what the borough's validation team looks for and where officers push back under the Croydon Local Plan 2018. Your pack is drawn to the council's residential design expectations from the first line — existing and proposed floor plans, elevations on every affected side, an OS-based location plan and a block plan, each at a recognised metric scale with a scale bar and paper size stated.
Because we track live decision data for Croydon, we can tell you before you commit whether your scheme reads as an approval or needs reshaping around a neighbour's daylight or a matched roofline. And if the planners push back, revisions are free until you have a decision — you never pay twice to reach a yes.
Plenty of Croydon home projects need no application at all — single-storey rear extensions, rear-dormer lofts and modest outbuildings can sit within permitted development. You will usually need a full application to Croydon Council where one of these is true:
Before you commit, it helps to see how Croydon Council is actually deciding. The figures below come straight from official planning statistics for the borough — and they explain why a policy-compliant, precisely scaled pack matters in an authority handling this volume. Croydon refusals cluster around a familiar set of Local Plan objections: overlooking and loss of privacy between close-set terraces, bulk that overbears a neighbour's rear window, and hip-to-gable lofts that unbalance a matched pair of interwar semis. We design against each before submission, which is how our clients land on the right side of the numbers.

The borough divides north from south. North Croydon — Thornton Heath, South Norwood, Selhurst, Broad Green, West Croydon and Norbury — is a fabric of Victorian and Edwardian terraces on tight plots strung along the Brighton main line and the Tramlink. Here the bread-and-butter work is the side-return kitchen extension, the closet-wing rear addition and the rear-dormer loft. South of the town centre, Shirley, Coulsdon, Purley, Sanderstead and Kenley turn interwar and Edwardian-suburban: 1930s semis and detached houses on generous gardens where wraparounds, hip-to-gable lofts and garage conversions dominate.
That geography changes the drawing. On a Selhurst terrace the pinch point is daylight to the neighbouring back-addition window, and a clean 45-degree line drawn on the proposed elevation settles the argument before the officer raises it. On a Sanderstead semi the sensitivity is the roofline: a hip-to-gable that breaks the symmetry of a paired frontage draws objection, so we detail the set-down, the ridge line and the materials that keep the pair reading as one composition.
Croydon has also absorbed sustained pressure for suburban intensification — the Local Plan 2018 steered growth toward the metropolitan centre and district hubs at Purley, Coulsdon and Addiscombe, and case officers are correspondingly practised. Unscaled or ambiguous drawings get bounced at validation or invite conditions; a precise, self-explaining pack is the cheapest insurance you can buy.

A side return on a South Norwood terrace, a wraparound in Sanderstead, a rear dormer within earshot of the New Addington tram — we draw to the way Croydon's case officers actually read a scheme, context first, objections answered on the page.
Croydon's validation checklist is unforgiving on scales and completeness. Every pack we prepare for the borough includes:
Each affected floor at 1:100 or 1:50, fully dimensioned and labelled, so a Croydon officer can read exactly what is added and what is retained.
Every elevation the work touches, materials annotated — Croydon routinely conditions brick, render and fenestration to protect the uniformity of its interwar suburbs.
OS-based, the application site edged red and any other land you control edged blue, on a recognised paper size with a north point.
The proposal set against boundaries, neighbouring properties and any protected trees — decisive where rear-garden amenity in the leafy south of the borough is in play.
Croydon loft and dormer schemes are usually asked for a roof plan and a section evidencing head heights and the dormer's set-back from the eaves.

Send your postcode and project. We score it against live Croydon decision data and flag conservation-area, Article 4 and Tramlink-corridor constraints on your specific road.
We measure the property and produce accurate existing plans and elevations — the baseline Croydon's validation team checks a proposal against first.
Chartered designers draw the scheme to the Croydon Local Plan 2018, resolving daylight, outlook and roofline-symmetry points on the page rather than in correspondence.
We submit through the Planning Portal, clear validation queries and liaise with your Croydon case officer across the eight-week determination period.
Croydon Council decides householder applications for Croydon, and its recent record and the permitted-development limits that apply here set out below give Addiscombe homeowners a realistic starting point before any drawing begins.

| Loft dormer permitted-development limit (Class B) | 40m³ terrace / 50m³ semi or detached |
| Single-storey rear extension depth (Class A) | 3m terrace / 4m detached |

| Statutory decision period | 8 weeks |
| Conservation / Article 4 status | Article 4 direction in force; PD removed in Addiscombe (Canning and Clyde Roads), Upper Norwood Triangle and Park Hill |
Croydon runs 3 points below the national average. Approval rate: MHCLG householder planning statistics for Croydon Council; permitted-development limits: GPDO 2015, Schedule 2, Part 1 (Classes A–B).
The statutory period is eight weeks from validation, and most straightforward Croydon householder applications are decided within it. Schemes in the Webb Estate or other conservation areas, or those needing amendments, can be extended by agreement. We monitor the case and answer officer queries quickly so the clock keeps moving.
Usually not — most Croydon loft conversions on the interwar semis of Purley, Shirley and Coulsdon fall under permitted development where the dormer sits on the rear slope, stays within the volume allowance and is set back from the eaves. You will need permission on flats, in conservation areas, or where an earlier condition removed roof PD rights. A hip-to-gable on a matched pair warrants careful detailing either way.
Croydon has numerous designated conservation areas, among them the Webb Estate and Upper Woodcote Village in Purley — William Webb's early-20th-century garden suburb — the Waldrons near South Croydon, Addiscombe's district centre and Chatsworth Road. Inside them, extensions and roof alterations face closer design scrutiny and some permitted development rights are restricted. We check your address against the council's designations before drawing anything.
A householder application in Croydon needs existing and proposed floor plans and elevations at 1:100 or 1:50, an OS-based location plan at 1:1250 with the site edged red, and a block plan at 1:500. Loft schemes usually add a roof plan and section. Our packs carry everything on the borough's validation checklist so the application clears first time.
Yes. We prepare the drawings, complete the forms, calculate the statutory application fee, submit through the Planning Portal and deal with Croydon's case officer on your behalf — including any requests for amendments. You never contact the council directly, and revisions stay free until you have a decision.
Most Croydon refusals are resolved by targeted amendment — pulling a dormer back, trimming a projection, or reworking a window that overlooks a neighbouring garden. We revise the drawings free of charge and resubmit; a repeat householder application within twelve months of the refusal usually attracts no further council fee.
