House Extension Drawings in Mitcham |

No Article 4 Direction covers Merton, which keeps the Mitcham permitted-development route open on unlisted houses. Mitcham presents as 1930s semi-detached, post-war estates, so massing and materials carry more weight in the Merton Council assessment than they would on an outer-London plot. Of the 28 conservation areas Merton designates, Wimbledon Village and John Innes are the ones that most often change how a Mitcham project is routed. The designation map is read street by street in Mitcham.

We map how Article 4 directions bite across CR4 before a line is drawn. On a Mitcham house the measurements bite through the 1930s semi-detached: it sets the original rear wall, and the roofline around Mitcham Cricket Green sets what ridge height will pass. The borough policy layer over every CR4 address is set out on Merton planning. The Mitcham survey then carries into loft conversion drawings in Mitcham if the project runs on to construction.

Validation at London Borough of Merton is the first delay a Mitcham applicant meets. We start with a full laser survey of the Mitcham address so the existing set is dimensionally right before anything proposed is drawn.

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.

London Borough of Merton publishes the Mitcham application online during consultation. You get the full Mitcham set as PDFs, plus CAD on request.

A CR4 objection about light or overlooking carries more weight than one about taste. We photograph the Mitcham property alongside the measurements for the record.

Shared walls are the norm in Mitcham; the notice period is not optional. Once consent is granted, architectural drawings follows for the CR4 property.

Mitcham is characterised by 1930s semi-detached, post-war estates, concentrated across CR4 in the Mitcham area. Across CR4 the 1930s semi-detached repeats often enough to be predictable, once it has been measured properly. Translated to the 1930s semi-detached here: 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. That is drawn out in the Mitcham proposed section. Because the Mitcham streetscape near Mitcham Cricket Green is consistent, departures in ridge height read immediately in an officer report.

Merton sets no special basement rule, so a Mitcham lower-ground scheme stands or falls on the engineering and the neighbours. We do not re-measure a CR4 property for each stage of the job.
