Planning and building regulation drawings in Croydon (CR0)

CR0 covers more ground than the name suggests, and it crosses a borough boundary. Central Croydon and Addiscombe fall under Croydon Council, while Beddington sits within the London Borough of Sutton despite sharing the postcode. Which council decides an application, and therefore which rules apply, depends on the street.

On the Croydon side, the housing around Addiscombe is largely Victorian and Edwardian: villas and bay-fronted terraces, the East India Estate grid laid out in the 1870s on land that once belonged to the East India Company's college, interwar semis in the residential streets, and later flats nearer the town centre. Chatsworth Road, Canning Road, Outram Road, Elgin Road, Clyde Road, Grant Road, Radcliffe Road and Addiscombe Road are among the streets. Family additions are the common projects here: rear and side extensions, loft conversions and garage-to-room conversions. Flats have no householder permitted development rights, so owners of the flats near the centre start from a different position.

Beddington has an old village heart, with Carew Manor, Beddington Park and a medieval church, and interwar semis and terraces on regular plots grew up around it. Church Lane, Guy Road, Sandhills and Queen Elizabeth's Walk are among its streets. Rear extensions, side infill and lofts are the common work, and low-lying ground towards the River Wandle can bring drainage and flood questions into a scheme.

Conservation designations matter in the Croydon part: Central Croydon, Chatsworth Road and East India Estate. On the uniform Victorian grid of the East India Estate, frontages are closely controlled so that they continue to match. We establish the borough, the conservation status and any Article 4 coverage before a line is drawn.

Planning in Croydon: what to know before you apply

The Chatsworth Road conservation area has an Article 4 direction removing permitted development for changes to front elevations, roofs and boundaries. Croydon also requires planning permission to turn a family house into a small HMO, meaning three to six unrelated sharers; one record describes that direction as borough-wide, while the council's summary refers to designated wards, so we confirm it for the address. The council also controls some office-to-residential changes in parts of the town centre. In any conservation area, roof enlargements, side extensions and rear extensions of more than one storey are not permitted development. Flats have no householder permitted development rights. For Beddington, we have found no Article 4 direction covering its part of CR0, and we check Sutton's wider directions before relying on permitted development; Sutton also expects extensions to respect the suburban building line. An application needs an ownership certificate or notice, not the freeholder's consent.

Applications are decided by Croydon Council — its planning pages.

A single-storey rear extension up to 4 m deep on a detached house, or 3 m on any other house, is Class A permitted development subject to the height and materials conditions.
An Article 4 direction applies here and may withdraw this freedom — the schedule must be checked before relying on it.
One or more constraints are unknown — we check the council's registers as part of the free appraisal.
Where permitted development applies, a lawful development certificate proves it for lenders and buyers.

This is a first-pass indication from the national rules, not planning advice for your property. Your council's registers, any Article 4 schedule and the exact dimensions decide it — the free appraisal checks all three before we recommend a route.

FAQ

Croydon (CR0) — FAQs

Is my Beddington home dealt with by Croydon?+

No. Beddington is in the London Borough of Sutton, so Sutton decides householder applications there even though the postcode is CR0. We confirm the borough from the exact address first, because the boundary matters at the edges.

Do I need permission to turn a family house in Addiscombe into a shared house?+

Quite possibly. Croydon's Article 4 direction means a small shared house, one occupied by three to six unrelated people, needs planning permission where the direction applies. We check its extent against your property.
