— Luxury home renovation · South London
Luxury renovation services across South London.
Period restoration to contemporary remodel, kitchen refurbishment to whole-house transformation — two decades of family-run building across South London’s premier postcodes.
South London is a borough of complete contrast. Grade II listed Victorian villas in Wimbledon Village. Riverside apartments at Nine Elms in Wandsworth. Edwardian semis behind the conservation areas of Bickley and Chislehurst. Mansion flats in Kensington and Chelsea behind RBKC’s strictest planning regime. Family homes on the Cator Estate Beckenham with private restrictive covenants. Each requires a different approach.
LMDEC LTD has spent two decades building across these postcodes. The work that matters most — full house refurbishment, extensions and loft conversions, period restoration — is delivered by an in-house team led by founder Lukasz Mazurek, with all trades coordinated under one LMDEC project manager
