Measured floor plans and elevations across CR0. A CR0 scheme is measured against Croydon Local Plan policy by Croydon Council officers.
If you own in Croydon, architectural drawings are scaled Croydon floor plans, elevations and sections describing a CR0 property as existing and as proposed. The Croydon Local Plan governs and they start with a laser measured survey of the Croydon address and carry every CR0 submission to Croydon Council, householder application through to full plans.
No Article 4 Direction covers Croydon, which keeps the Croydon permitted-development route open on unlisted houses. Being post-war centre, Edwardian residential ring, Croydon rewards schemes that sit quietly beside Whitgift Centre. Conservation status changes the Croydon route entirely — Shirley Park being the usual case among the 24 designations in Croydon. That boundary is verified for the CR0 property at the outset.
Article 4 coverage across CR0 is confirmed before we quote, not after. What the Croydon building allows is established first; what Croydon Council allows, second. The borough policy layer over every CR0 address is set out on Croydon planning. The Croydon survey then carries into loft conversion drawings in Croydon if the project runs on to construction.



Before Croydon Council determines anything, London Borough of Croydon has to validate the Croydon submission — one to two weeks, longer if a plan is missing. The Croydon survey comes first, because a proposal drawn on wrong existing plans fails validation later.
Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.
Consultation responses on a Croydon scheme are public and readable before the decision. The Croydon pack is validated against London Borough of Croydon requirements before submission.
Objection volume on Croydon cases is public — we read it before advising. The Croydon survey records every opening, level change and structural wall.
Shared walls are the norm in Croydon; the notice period is not optional. Once consent is granted, house extension drawings follows for the CR0 property.
Croydon is characterised by edwardian terraces, post-war flats, concentrated across CR0 in the Croydon / Addiscombe / Shirley area. Across CR0 the edwardian terraces repeats often enough to be predictable, once it has been measured properly. Applied to CR0 property: edwardian back additions here are often out of plumb, which matters once a steel goes in. It shapes what a CR0 scheme can realistically achieve. Croydon Council reads a Croydon elevation against its neighbours first.
A CR0 dig turns on engineering more than on policy. Because the Croydon survey is drawn properly once, planning permission for CR0 properties and building regulations drawings build on it rather than starting again.
Surveyors travel to CR0 addresses from the studio; the nearest stations are East Croydon, London Bridge station, West Croydon station, Surrey Street Pumping Station, Croydon. Appointments are booked in Croydon on weekdays and Saturdays, and the measured survey of a standard edwardian terraces takes two to three hours.
Croydon lies 9.5 miles (15 km) south of Charing Cross, on Ordnance Survey grid reference TQ335655. That is the reference the Croydon site plan is drawn over. Source.
Practical detail for a Croydon submission: East Croydon and London Bridge station and West Croydon station and Surrey Street Pumping Station, Croydon serve the area; CR0 addresses are written to CROYDON; dialling code 02001689 (; Grade I Croydon Minster and Grade I Whitgift Foundation and Grade II Grants of Croydon sit within the Croydon setting and are listed. Site plans are drawn to the address as Croydon Council holds it.
Croydon work spans CR0 (Croydon / Addiscombe / Shirley), shared with Addiscombe, Shirley — the designations change with the district line.
Work in Croydon clusters around Wellesley Road, Saffron Square, Beulah Hill, Sydenham Hill, Hyde Park, Ruskin Square, Broad Green and Pilgrims' Way. most Croydon sites are within walking distance of East Croydon or London Bridge station or West Croydon station. and Grade I Croydon Minster, Grade I Whitgift Foundation, Grade II Grants of Croydon are listed, which pulls neighbouring CR0 proposals into a setting assessment.
Beyond Croydon we cover Morden (SM4), Mitcham (CR4), Colliers Wood (SW19), South Wimbledon (SW19), Clapham (SW4), Brixton (SW2, SW9), and cross into Merton. A consent granted a mile from Whitgift Centre is not a precedent for the plot next to it.

The variables on a CR0 job are structural: party walls, floor levels, and whether the Shirley Park designation adds a heritage statement.
Statutory application fees are set by regulation, not by the council: £548 householder, £610 for a new dwelling, £274 for a lawful development certificate, £249 for prior approval.
The statutory element is payable to London Borough of Croydon, not to us. London planning approval-rate dataset · Croydon planning · the London architectural drawings pillar page · architectural drawings in Morden.
The technologist who surveys your Croydon property signs the drawings. For difficult Croydon sites — anything in Shirley Park, anything overlooking Whitgift Centre — the pre-application route is cheap insurance.
Drawings are produced by chartered members of the Chartered Institute of Architectural Technologists (MCIAT), the professional body for technical design and building-regulations competence. First-time approval across our London caseload is 98%. Statutory fees shown are those in force in England in 2026 under the Town and Country Planning (Fees for Applications) Regulations. Confirm your local authority at gov.uk and submission requirements on the Planning Portal. Studio: 71–75 Shelton Street, London WC2H 9JQ.
We can usually confirm the Croydon planning route from the address alone. This Croydon page was reviewed in August 2026.
Not for every Croydon project. Where the house is unlisted and clear of Shirley Park, permitted development may cover the work. No Article 4 Direction covers Croydon, which keeps the Croydon permitted-development route open on unlisted houses.
Check Shirley Park first. Croydon designates 24 areas, and Croydon sits against that one most often.
Mainly edwardian terraces, post-war flats in Croydon, all of it laser-measured before design.
Across Croydon — Morden among them — and into Merton. Each CR0 street is assessed on its own designations, which is why the pages are separate.
