Planning permission drawings, rear extensions, and loft conversions for West Wickham's 1930s semis and bungalows. MCIAT chartered, fixed fees, Bromley planning expertise built in.
West Wickham sits in the BR4 postcode in the south of the London Borough of Bromley, on the border with Croydon. The leafy streets, 1930s semis, and bungalows make this one of south London's most consistent extension markets.
1930s semi-detached stock: The majority of West Wickham's housing is inter-war semi-detached on standard plots. These properties typically have rear gardens suitable for 4m+ extensions and hipped roofs suitable for hip-to-gable loft conversions with rear dormers.
Bungalow conversions: West Wickham has a notable stock of 1930s bungalows. Loft conversions — adding a first floor via a full raise-the-roof or dormer — are popular. Full first-floor extensions are also achievable where the original roof allows.
Permitted development: Outside conservation areas, most West Wickham properties retain full PD rights. Rear extensions under prior approval, loft conversions under Class B, and two-storey side extensions within parameters. We confirm eligibility and prepare drawings.
Bromley design guidance: Bromley Council publishes clear design expectations. Two-storey side extensions must be subordinate and set back. Roof extensions should match existing materials. We design to these standards.

Direct answers to the questions West Wickham homeowners ask us every week about planning, extensions, and loft conversions.
Start a free quoteOften yes — it depends on whether the addition falls within PD or requires planning permission. We assess the height, volume, and material constraints of Class A/B permitted development and advise the right route.
In most cases no — rear extensions up to 6m (detached) or 4m (semi) fall within PD with prior approval. Larger schemes need planning permission. We confirm and prepare drawings.
Hip-to-gable loft conversions with rear dormers are the standard pattern and usually fall within PD. We prepare the planning notification and full building regs drawings.
