Construction Trends in Lewisham
Lewisham has a dense mix of Victorian and Edwardian terraces, especially around Catford, Hither Green, Forest Hill, Lee, Brockley, and Ladywell. On tighter plots, planning applications often focus on rear additions, loft conversions, and internal layout changes that make older homes more practical. Further south towards Sydenham and Bell Green, the housing mix opens up slightly, with more inter-war semis and larger plots creating scope for side extensions, double-storey work, garage conversions, and wider refurbishments.
