Planning permission drawings, extensions, loft conversions, and garage conversions for Welling's 1930s and post-war homes. MCIAT chartered, fixed fees, Bexley planning expertise built in.
Welling sits in the DA16 postcode within the London Borough of Bexley, centred on Welling High Street and the surrounding residential streets. The mix of 1930s semis and post-war housing generates consistent demand for extensions and loft conversions.
1930s and post-war stock: Welling's housing stock is dominated by inter-war and post-war semis on standard plots. These properties typically have rear gardens suitable for 4–6m rear extensions and hipped roofs suitable for hip-to-gable loft conversions. We design schemes that add a full bedroom, en-suite, or open-plan kitchen-diner.
Garage conversions: Many Welling properties have attached garages that are no longer used for parking. Converting the garage to habitable space — study, playroom, or extra bedroom — is a cost-effective way to add 12–15 square metres. We prepare the building regulations drawings required for the conversion.
Permitted development: Outside any small conservation area pockets, Welling properties retain full PD rights. Rear extensions under prior approval, loft conversions under Class B, and two-storey side extensions within certain parameters. We confirm your eligibility and prepare the necessary drawings.
Bexley's design expectations: Bexley Council publishes clear guidance on residential extensions. Two-storey side extensions should be set back and down. Roof extensions should match the existing roof profile. We design to these standards.

Start a free quoteUsually no — garage conversions within the existing footprint typically fall within permitted development. However, Building Regulations approval is always required to address thermal performance, ventilation, and structural changes. We prepare the building regs drawings.
Often yes. Two-storey rear extensions up to 3m are permitted development in many cases. Two-storey side extensions may require planning permission depending on proportions. We confirm the position and prepare appropriate drawings.
Welling's inter-war semis are ideal for hip-to-gable loft conversions with rear dormers. Most fall within PD. We design schemes that maximise headroom and include the structural calculations.
