House Extension Drawings in Belvedere |

No Article 4 Direction covers Bexley, which keeps the Belvedere permitted-development route open on unlisted houses. Officers see Belvedere as 1930s semi-detached, post-war flats — design that ignores it struggles. Belvedere sits close enough to Welling that designation should be checked at the outset, not after design. We confirm the DA17 designation at survey rather than assuming it.

Article 4 coverage across DA17 is confirmed before we quote, not after. On a Belvedere house the measurements bite through the 1930s semi-detached: it sets the original rear wall, and the roofline around Belvedere station sets what ridge height will pass. The borough policy layer over every DA17 address is set out on Bexley planning. The Belvedere survey then carries into architectural drawings in Belvedere if the project runs on to construction.

The DA17 bottleneck is validation. London Borough of Bexley needs one to two weeks, and a missing drawing resets it. A Belvedere project opens with an on-site laser survey, which is what makes the later Bexley Council submission robust against a validation query.

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.

Expect a site visit to the Belvedere property during the consultation period. Scales, north point and drawing numbers all follow Bexley Council validation requirements.

Speaking to DA17 neighbours before submission avoids most of it. Party wall positions on a Belvedere terrace are located during the survey.

Most Belvedere terraces share a flank wall, so party wall notices apply. Once consent is granted, planning permission follows for the DA17 property.

Belvedere is characterised by 1930s semi-detached, post-war flats, concentrated across DA17 in the Belvedere area. On Belvedere plots, structure follows the 1930s semi-detached that is already there. The Belvedere 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. We resolve it before the Belvedere design is fixed. Bexley Council reads a Belvedere elevation against its neighbours first.

Bexley Council assesses Belvedere basements on standard grounds. Because the Belvedere survey is drawn properly once, building regulations drawings for DA17 properties and loft conversion drawings build on it rather than starting again.

Your Belvedere drawings are produced under professional charter, not subcontracted out and rubber-stamped. Where Welling or a DA17 party wall complicates a Belvedere scheme, Bexley Council sees it early.

First-time approval across our London caseload is 98%. Statutory fees shown are those in force in England in 2026 under the Town and Country Planning (Fees for Applications) Regulations.
