Tooting is one of South London's most vibrant and rapidly gentrifying residential areas, sitting in the SW17 postcode between Balham, Streatham, Wandsworth and Wimbledon. The area is characterised by long streets of Victorian and Edwardian terraced houses with back additions — ideally suited to L-shaped dormer loft conversions. Tooting's excellent transport links via the Northern line at Tooting Bec and Tooting Broadway, its thriving high street and consistently rising property values make loft conversions here one of South London's best investments. LCCL Construction delivers loft conversions across Tooting and all of South London as part of our complete design and build service.
Best Loft Conversion Types for Tooting SW17 Properties
Tooting's Victorian and Edwardian terraces with back additions are ideally suited to L-shaped dormer loft conversions which extend the dormer over both roof planes creating two bedrooms rather than one. Standard dormer conversions are also popular and mansard conversions work well for the larger properties around Tooting Bec Common.
