House Extension Drawings in Barnehurst |

No Article 4 Direction covers Bexley, which keeps the Barnehurst permitted-development route open on unlisted houses. Barnehurst is 1930s semi-detached — a house extension drawings submission has to answer that context rather than a generic London template. A DA7 property inside Old Bexley loses part of its permitted development and generally goes to Bexley Council in full. Conservation status is checked against the Barnehurst address before design.

We check Article 4 directions against the Barnehurst address first — it changes what is worth drawing. Rear wall, floor levels and the Barnehurst station roofline are the three Barnehurst constraints. The borough policy layer over every DA7 address is set out on Bexley planning. The Barnehurst survey then carries into building regulations drawings in Barnehurst if the project runs on to construction.

Validation alone costs London Borough of Bexley one to two weeks even when the Barnehurst pack is complete, and that queue — not the determination — is where most DA7 delay starts. The first visit to Barnehurst 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.

A Barnehurst case only reaches committee if it draws significant objection. We issue the DA7 drawings numbered and revision-controlled.

London Borough of Bexley weighs material objections only — a Barnehurst neighbour disliking the design is not one. We measure the DA7 property room by room, including ceiling heights and floor falls.

On Barnehurst stock the party wall stage is routine and worth timetabling. Once consent is granted, loft conversion drawings follows for the DA7 property.

Barnehurst is characterised by 1930s semi-detached, concentrated across DA7 in the Bexleyheath / Barnehurst area. How the 1930s semi-detached in Barnehurst was built decides what can be opened up and where the load has to go. In practice on a Barnehurst job, 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. It is the first thing checked at the Barnehurst survey. London Borough of Bexley officers compare a DA7 scheme to the block it sits in, not to a policy number.

Lower-ground schemes in Barnehurst answer to neighbours and groundwater. Survey data from the Barnehurst property flows straight into architectural drawings for DA7 properties or planning permission without a second site visit.

Local landmarks that shape a Barnehurst application

• Slade Green — closet wings that change how a rear extension meets the Slade Green back addition.
• Barnehurst station — height and massing nearby are argued against this frontage.
• Northumberland Heath — nearby 1930s semi-detached takes its scale from this frontage.
