Hammersmith is one of West London's most well-connected and desirable residential areas, sitting between Fulham, Chiswick and Shepherd's Bush. The W6 postcode contains a high concentration of large Victorian and Edwardian terraced houses that are well suited to loft conversions, alongside strong property values driven by excellent transport links and proximity to central London. LCCL Construction delivers loft conversions across Hammersmith and all of West London as part of our complete design and build service.
Loft Conversions Hammersmith: Best Types for Local Properties
Hammersmith's Victorian terraced houses are ideally suited to dormer loft conversions and L-shaped dormer loft conversions. Properties with a back addition — common across W6 — suit L-shaped conversions which create two bedrooms rather than one at modest additional cost. Given the premium property values in Hammersmith, mansard loft conversions are also a compelling option for maximum space.
