House Extension Drawings in Shirley |

No Article 4 Direction covers Croydon, which keeps the Shirley permitted-development route open on unlisted houses. Shirley reads as 1930s semi-detached, and that is the context a CR0 scheme is judged in. Old Coulsdon is the designation that most often reshapes a Shirley proposal; Croydon carries 24 of them. Every Shirley enquiry starts with that check.

The Shirley Article 4 position is established at survey, before design. The 1930s semi-detached in Shirley decides the depth before policy does. The borough policy layer over every CR0 address is set out on Croydon planning. The Shirley survey then carries into building regulations drawings in Shirley if the project runs on to construction.

Validation alone costs London Borough of Croydon one to two weeks even when the Shirley pack is complete, and that queue — not the determination — is where most CR0 delay starts. No Shirley design work starts until the measured survey is complete.

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.

We monitor the CR0 case and respond to officer queries during the period. Output for Shirley: dimensioned PDFs at the scales the authority specifies.

Neighbour comment is what shapes most Shirley decisions; policy rarely decides alone. Party wall positions on a Shirley terrace are located during the survey.

On Shirley stock the party wall stage is routine and worth timetabling. Once consent is granted, loft conversion drawings follows for the CR0 property.

Shirley is characterised by 1930s semi-detached, concentrated across CR0 in the Croydon / Addiscombe / Shirley area. On Shirley streets the 1930s semi-detached sets the structural grammar for everything that follows. For Shirley owners this matters because 1930s semis here have the deepest rear gardens in the area, which is why the 6 m and 8 m larger-home prior approval route gets used so often. We resolve it before the Shirley design is fixed. Because the Shirley streetscape near Shirley Park is consistent, departures in ridge height read immediately in an officer report.

Lower-ground schemes in Shirley answer to neighbours and groundwater. Survey data from the Shirley property flows straight into architectural drawings for CR0 properties or planning permission without a second site visit.

What changes a Shirley fee is the property: 1930s semi-detached construction, shared walls on CR0, and whether heritage input is needed.

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.

That fee is collected by London Borough of Croydon when the CR0 application is lodged. London planning approval-rate dataset · Croydon planning · the London house extension drawings pillar page · house extension drawings in Wallington.
