Wimbledon and Raynes Park are two of South West London's most desirable residential areas, known for the world-famous Wimbledon tennis championships, Wimbledon Common and some of the highest property values in outer South West London. The SW19 and SW20 postcodes contain a high concentration of large Victorian, Edwardian and inter-war semi-detached and terraced houses that are exceptionally well suited to loft conversions of all types. LCCL Construction delivers loft conversions across Wimbledon, Raynes Park and all surrounding South West London areas as part of our complete design and build service.

Loft Conversions Wimbledon: Best Types for Local Properties
Wimbledon's large Edwardian and Victorian semi-detached houses are ideally suited to hip to gable loft conversions, creating the maximum additional bedroom space by replacing the sloping hip end of the roof with a vertical gable. Victorian terraced houses in Wimbledon and Raynes Park suit dormer and L-shaped dormer conversions. The high property values across SW19 make mansard loft conversions a compelling option. See our full guides on hip to gable loft conversions and dormer loft conversions.
