Frequently asked questions in Croydon
Do I need planning permission for a rear extension in Croydon
Not always. Many rear extensions can be permitted development, but it depends on your house type, site constraints, and whether any restrictions apply. We confirm the best route after a quick review of your address and goals.
How long does Croydon Council take to decide
Timescales vary, but householder applications are commonly decided within several weeks after validation. If you need certainty for a permitted development style scheme, a Lawful Development Certificate can be a safer option.
Do you manage the full application to Croydon Council
Yes. We prepare drawings, complete forms, upload documents, submit to the council portal, and respond to planning officer queries through to decision.
What drawings do I get for building regulations
A coordinated package typically includes plans, elevations, sections, key construction details, notes for compliance, and coordination points for structure, ventilation, insulation, and drainage so builders can price and build correctly.
Local planning knowledge for Croydon projects
Croydon includes conservation areas, mixed housing stock and many family homes with scope for larger extensions and loft conversions. We shape each scheme to suit local character and neighbour amenity so approval chances are as strong as possible.
