Planning permission drawings, loft conversions, extensions, and building regulations for Lewisham's Victorian and Edwardian properties. MCIAT chartered, fixed fees, SE13 planning expertise built in.
Lewisham sits in the SE13 postcode at the heart of the London Borough of Lewisham. The town centre is undergoing major regeneration, while its surrounding residential streets — lined with Victorian terraces and Edwardian houses — are increasingly popular with families looking to extend and improve rather than move.
Victorian and Edwardian terraces: Lewisham's residential streets offer excellent potential for loft conversions, rear extensions, and side-return infills. The typical two- or three-storey terrace has a good roof void and adequate garden depth for single-storey extensions. We survey each property and advise on the most effective use of space.
Permitted development opportunities: Much of residential Lewisham sits outside conservation areas, meaning permitted development rights are available for rear dormers, single-storey extensions, and outbuildings. We confirm PD eligibility and prepare the building regulations drawings needed for Building Control sign-off.
Regeneration context: Lewisham town centre's ongoing regeneration means some adjacent residential streets are subject to area-specific planning policies. We check site-specific designations as part of every project assessment.
Building regulations: All extensions and conversions must comply with current Building Regulations. We prepare fully detailed building regulations drawings covering structural, fire safety, thermal, and acoustic requirements.

Start a free quoteYes, loft conversions are popular in Lewisham. Most Victorian terraces outside conservation areas can add rear dormers under permitted development. We survey your roof, confirm PD eligibility, and prepare building regulations drawings.
Under permitted development, terraced houses can extend up to 4 metres at single storey without planning permission. Semi-detached houses have a 6-metre allowance. Within any conservation areas, planning permission may be required. We confirm what applies to your property.
