Building Regulations Drawings in Catford |

No Article 4 Direction covers Lewisham, which keeps the Catford permitted-development route open on unlisted houses. The Catford setting is 1930s semi-detached, post-war centre, which shapes what passes near Catford Cat. If your Catford address is inside Blackheath, treat permitted development as reduced and plan for a full Lewisham Council application. Every Catford enquiry starts with that check.

The Catford Article 4 position is established at survey, before design. A SE6 survey answers most of it — where the 1930s semi-detached allows the rear wall to go. The borough policy layer over every SE6 address is set out on Lewisham planning. The Catford survey then carries into planning permission in Catford if the project runs on to construction.

The SE6 bottleneck is validation. London Borough of Lewisham needs one to two weeks, and a missing drawing resets it. A Catford project opens with an on-site laser survey, which is what makes the later Lewisham Council submission robust against a validation query.

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.

Officer queries on a Catford application come to us, not to you. A Catford pack that misses a scale bar is a pack London Borough of Lewisham will reject — ours do not.

We would rather redesign a SE6 rear elevation than argue an objection. A Catford measured survey captures the roof structure as well as the plan.

Late notices are what stall Catford sites more than planning does. Once consent is granted, loft conversion drawings follows for the SE6 property.

Catford is characterised by 1930s semi-detached, post-war flats, concentrated across SE6 in the Catford / Bellingham area. Every Catford scheme starts from what is actually there: 1930s semi-detached, post-war flats, surveyed to the millimetre before a proposal is drawn. On SE6 plots specifically, 1930s cavity walls here take standard full-fill or partial-fill detailing, which keeps the Part L calculation straightforward. That detail drives the SE6 construction sequence. The prevailing Catford eaves line is the reference Lewisham Council uses, which is why the proposed elevation is drawn with the neighbours on it.

Digging under a Catford house is a structural question before a planning one. Where the project also touches house extension drawings for SE6 properties or architectural drawings, the same measured survey of the Catford property carries across — you pay for the survey once, not per application.
