Building work in Chislehurst: area guide

This is our area guide to building work in Chislehurst (BR7, Bromley): the housing, the council rules that apply (Bromley Council for planning) and every service we offer here. For whole-house refurbishment go to Home renovation in Chislehurst.

Houses near Chislehurst Common tend to be larger and older than the rest of BR7, much of which was built after the war, and that decides which job you are looking at before anyone picks up a tool. Deeper plans, several chimney stacks, complex roofs with valleys and dormers, tile hanging or render on the upper storey, and secondary rear wings built for a way of running a household nobody runs any more. Work here often spans the whole house, but it still breaks down into structure, roof and rooms. GS Renovation covers BR7 as a visiting contractor with no premises in the area and appoints the structural engineers.

Count the homes in Chislehurst and you get about 10,240: 67% built since 1945, 19% between the wars and 12% before 1919, with flats at 22% and houses at 78%.

Deep plans, long spans and complicated roofs put steel first in BR7

A wide house creates a structural problem a terrace never has: distance. Joining two large rooms across a deep plan means a long span, a heavy beam and bearings at each end taking a serious load, which the structural engineer we appoint designs in full, so RSJ installation comes before any open-plan conversion finish. Getting that weight into the middle of a house involves access routes, temporary works and sometimes lifting equipment on the drive. We work that out at survey, because a beam delivered in pieces and spliced changes both design and programme.

The roofs decide the next job. Cut roofs of this size rely on purlins, struts and hangers, and those struts commonly land on first floor walls that owners assume are partitions, so taking one out is load-bearing wall removal, not a strip-out. Remove one without support and the roof tells you within days. Valleys, secondary ridges over rear wings and old lead work recur too, since a leak that has run quietly for years usually shows itself as a rotten purlin end at exactly the bearing point you now need. We open up and inspect before any design is finalised.

Sequencing a BR7 house puts structure first and rooms last

A job this size lives or dies by its order of work. Structural alterations and roof repairs come first, then first fix electrics, plumbing and any heating renewal, then plaster, then joinery, with kitchen renovation and bathroom renovation near the end and decoration last. Out of sequence trades produce the jobs we are called in to rescue, where a good floor was laid before the plasterers arrived. One person holds the programme, books Bromley Council building control inspections and sends a written update each week. That sequence is a home renovation.

Consents are checked at the outset rather than mid-project. Some properties in this part of the borough are listed, others sit in conservation areas, where side, two-storey and roof extensions lose their permitted development rights, and the two have entirely different consequences: listed building consent covers internal work, while a conservation area controls the outside. We establish the position for your address with the council before drawings are commissioned, then build only to what is approved. Where a house is occupied through part of the programme, the works are zoned so a kitchen and a bathroom stay usable for as long as the sequence allows.
