Building work in Welling: area guide

This is our area guide to building work in Welling (DA16, Bexley): the housing, the council rules that apply (Bexley Council for planning) and every service we offer here. For whole-house refurbishment go to Home renovation in Welling.

Three quarters of Welling's homes were built between the wars, far more than the borough as a whole. The DA16 streets running between the High Street, Danson Park and Bexley Woods are mostly semi-detached houses with some short terraces among them, side access is often a shared path, and the neighbours are close to everything you do, so many structural jobs here are also party wall jobs. The construction is cavity walled and regular, which keeps surveying accurate. Quotations follow a visit to measure the property.

The stock in the Welling statistical area runs to roughly 4,020 dwellings, 21% of them flats and 78% houses, built 5% before 1919, 76% between 1919 and 1939 and 18% after 1945.

An interwar semi usually grows backwards, not sideways

On a semi the party wall is on one side and the flank on the other, often with only a shared path beside it, and in the short terraces there are party walls on both sides. Either way most extension work goes backwards, so the depth does most of the heavy lifting and light to the existing middle room has to be settled at design stage, usually with rooflights or a glazed section, rather than discovering afterwards that the original room has gone dark. Structural openings into the back of the house are designed by an engineer, with bearings that frequently land in the shared walls.

Inside, these houses respond well to modest structural change. Removing the wall between the front room and the middle room is a load-bearing wall removal job, and taking out a chimney breast that is eating a corner a chimney breast removal one. Both change how the ground floor works without touching the footprint, both need steel the engineer designs, and both are inspected by building control. Cavity walls are easier than solid ones to insulate and to open, but the cavity still has to be closed correctly and a tray installed where new work meets old, or damp finds its way in.

Party walls, programme and keeping the street onside before steel

Where a house is attached, almost anything structural against the shared wall triggers duties under the Party Wall etc. Act 1996. RSJ installation bearing into a shared wall, cutting a breast out of a shared stack, or excavating foundations near a neighbouring wall all require notice to be served before work starts, with notice periods of one to two months. Serving those early costs nothing and protects the programme. Serving them late, or not at all, is how a job ends up stopped by a surveyor while the scaffold stands idle and the trades are booked elsewhere.

The rest is ordinary courtesy applied consistently. Neighbours are told when the noisy stages fall and roughly how long they will last. Deliveries are timed so the shared access is not blocked at school run or when people are getting home. Waste goes into a skip on the drive if there is room and into booked bagged collections if there is not. One person owns all of that communication, so there is a single person to speak to rather than a different trade every week with a different answer.
