House Extension Drawings in Morden |

No Article 4 Direction covers Merton, which keeps the Morden permitted-development route open on unlisted houses. Morden is 1930s semi-detached, post-war flats — a house extension drawings submission has to answer that context rather than a generic London template. Where a Morden property sits inside Wimbledon Village or John Innes — two of Merton's 28 designations — permitted development narrows and a full Merton Council submission is usually quicker. We plot the Morden site against the designation before quoting.

That mapping of Article 4 directions across Morden happens before design, which is what keeps the Merton Council route predictable. Rear wall, floor levels and the Morden Tube roofline are the three Morden constraints. The borough policy layer over every SM4 address is set out on Merton planning. The Morden survey then carries into loft conversion drawings in Morden if the project runs on to construction.

Merton Council will not register a Morden application until validation completes. The first thing we do in Morden is measure — every room, every level change.

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.

Amendments during the Morden determination are handled without a resubmission where possible. The Morden pack is validated against London Borough of Merton requirements before submission.

Speaking to SM4 neighbours before submission avoids most of it. The Morden survey records every opening, level change and structural wall.

The party wall step is not optional on shared Morden walls, and serving late is what stalls sites. Once consent is granted, architectural drawings follows for the SM4 property.

Morden is characterised by 1930s semi-detached, post-war flats, concentrated across SM4 in the Morden area. On Morden streets the 1930s semi-detached sets the structural grammar for everything that follows. The Morden version of that is simple: 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. On Morden plots that shows up in the section drawings. A Morden proposal that breaks the prevailing eaves line invites a refusal.

Lower-ground schemes in Morden answer to neighbours and groundwater. A Morden survey done once feeds planning permission for SM4 properties and building regulations drawings later.

Streets and landmarks we survey around Morden

• Morden Hall Park — terraced rear elevations — the Morden Hall Park party wall position is drawn first.
• Motspur Park — terraced rear elevations — the Motspur Park party wall position is drawn first.
• Raynes Park — front-to-back level changes that drive the Raynes Park section drawings.
• Merton Park — roof profiles that set the ridge datum Merton Council measures a Merton Park dormer against.
• Worcester Park — terraced rear elevations — the Worcester Park party wall position is drawn first.
• Morden Park — shared flank walls, so Morden Park party structure notices go out before work starts.
• Morden Tube — a Morden roof extension is judged against the datum it sets.
• Epsom Hospital — the surrounding 1930s semi-detached takes its scale from it.
• Sutton Common — massing on adjoining SM4 plots is tested against it.
