House Extension Drawings in Hammersmith |

An Article 4 Direction applies across Hammersmith and Fulham, so check it before assuming Hammersmith permitted development survives. Officers see Hammersmith as Victorian terraces, riverside character — design that ignores it struggles. Inside the Brackenbury Village boundary — one of 45 such designations in Hammersmith and Fulham — a Hammersmith scheme normally goes straight to a full Hammersmith & Fulham Council application rather than relying on permitted development. The designation map is read street by street in Hammersmith.

The Hammersmith Article 4 position is established at survey, before design. Measure a W6 property and the victorian terraces answers most of it — where the original rear wall sat, and what height the Hammersmith street will carry. The borough policy layer over every W6 address is set out on Hammersmith and Fulham planning. The Hammersmith survey then carries into planning permission in Hammersmith if the project runs on to construction.

Validation alone costs London Borough of Hammersmith and Fulham one to two weeks even when the Hammersmith pack is complete, and that queue — not the determination — is where most W6 delay starts. The first visit to Hammersmith is a measured survey — every room, every opening, every level change recorded on site.

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 Hammersmith and Fulham publishes the Hammersmith application online during consultation. Nothing leaves for a Hammersmith address until it matches the local validation checklist.

London Borough of Hammersmith and Fulham weighs material objections only — a Hammersmith neighbour disliking the design is not one. Everything drawn for a W6 address traces back to a measurement taken on site.

Serve W6 party wall notices before work starts, not after. Once consent is granted, building regulations drawings follows for the W6 property.

Hammersmith is characterised by victorian terraces, mansion blocks, concentrated across W6 in the Hammersmith / Brackenbury Village area. What the victorian terraces in Hammersmith allows is a construction question first and a planning question second, and the survey answers it. Reading that across to Hammersmith stock: the side-return infill is the classic move on these Victorian terraces — 3 m of permitted development depth plus the width of the original side passage. That is the Hammersmith constraint Hammersmith & Fulham Council will look for. The W6 terrace sets the datum; departures from it show up in the officer report.

Hammersmith and Fulham sets no special basement rule, so a Hammersmith lower-ground scheme stands or falls on the engineering and the neighbours. We do not re-measure a W6 property for each stage of the job.
