House Extension Drawings in Kensington |

An Article 4 Direction applies across Kensington and Chelsea, so check it before assuming Kensington permitted development survives. What defines Kensington is that it is Georgian and Victorian stucco terraces, and design decisions here answer to that rather than to a pattern book. Kensington sits close enough to Chelsea that designation should be checked at the outset, not after design. Conservation status is checked against the Kensington address before design.

We check Article 4 directions against the Kensington address first — it changes what is worth drawing. Everything on a Kensington scheme is measured from the stucco terraces outward. The borough policy layer over every W8 address is set out on Kensington and Chelsea planning. The Kensington survey then carries into architectural drawings in Kensington if the project runs on to construction.

A Kensington application is not live until Royal Borough of Kensington and Chelsea validates it, which takes one to two weeks on a complete pack. Step one at a W8 address is a full measured survey of the existing building.

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 Kensington application come to us, not to you. We issue the W8 drawings numbered and revision-controlled.

We design Kensington schemes to answer the amenity objection before it is written. We photograph the Kensington property alongside the measurements for the record.

On Kensington terraces the flank wall is usually shared, so the party wall notice should go out well before work starts. Once consent is granted, planning permission follows for the W8 property.

Kensington is characterised by stucco terraces, listed buildings, concentrated across W8 in the Kensington area. W8 construction is stucco terraces-led, and the survey establishes what it carries. What that means for a W8 address: 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 detail drives the W8 construction sequence. Massing on a Kensington scheme is argued against the Kensington Palace street rhythm.

A W8 dig turns on engineering more than on policy. A Kensington survey done once feeds building regulations drawings for W8 properties and loft conversion drawings later.
