House Extension Drawings in Welling |

No Article 4 Direction covers Bexley, which keeps the Welling permitted-development route open on unlisted houses. In Welling the streetscape argument usually decides the case before the numbers do, because the area is 1930s semi-detached. Bexley has 16 conservation areas, and Welling is the one that most often covers Welling stock. That boundary is verified for the DA16 property at the outset.

Before drawing anything for Welling, we check Article 4 directions against the DA16 boundary. A DA16 survey answers most of it — where the 1930s semi-detached allows the rear wall to go. The borough policy layer over every DA16 address is set out on Bexley planning. The Welling survey then carries into architectural drawings in Welling if the project runs on to construction.

Before Bexley Council determines anything, London Borough of Bexley has to validate the Welling submission — one to two weeks, longer if a plan is missing. The Welling job starts with a laser survey, not a sketch.

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.

Most Welling householder cases are decided under delegated powers, not committee. Output for Welling: dimensioned PDFs at the scales the authority specifies.

We would rather redesign a DA16 rear elevation than argue an objection. Drainage runs and manhole positions on the DA16 plot are picked up on the day.

Party wall procedure runs alongside the Welling application, not after it. Once consent is granted, planning permission follows for the DA16 property.

Welling is characterised by 1930s semi-detached, concentrated across DA16 in the Welling area. Welling rewards a survey-first approach: the 1930s semi-detached rarely matches its own original drawings. On DA16 plots specifically, 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 a Welling terrace it governs the rear opening width. Height on a Welling proposal is measured against its neighbours, not against a policy number; the Welling High Street terraces set that datum.

Lower-ground schemes in Welling answer to neighbours and groundwater. If a Welling project extends into building regulations drawings for DA16 properties or loft conversion drawings, the survey is already done.

Streets and landmarks we survey around Welling

• Shooters Hill — frontages visible from the highway, so Welling materials detail governs the Shooters Hill elevation.
• Watling Street — terraced rear elevations — the Watling Street party wall position is drawn first.
• Upper Wickham Lane — closet wings that change how a rear extension meets the Upper Wickham Lane back addition.
• Slade Green — roof profiles that set the ridge datum Bexley Council measures a Slade Green dormer against.
• Welling High Street — proposals in its setting are drawn with the Welling context elevation.
• Welling School — height and massing nearby are argued against this frontage.
• Eastern Orthodox Church — nearby 1930s semi-detached takes its scale from this frontage.
• Bexley Grammar School — height and massing nearby are argued against this frontage.
