Notting Hill is one of West London's most iconic and desirable neighbourhoods, characterised by its large Victorian terraced houses, vibrant Portobello Road market and some of the highest property values in London. The W11 postcode and surrounding areas of W10 and W2 contain a high concentration of large Victorian stucco-fronted and brick terraced houses that are exceptionally well suited to loft conversions. LCCL Construction delivers loft conversions across Notting Hill and all of West London as part of our complete design and build service.
Loft Conversions Notting Hill: Best Types for Local Properties
Notting Hill's large Victorian terraced houses are exceptionally well suited to dormer loft conversions and L-shaped dormer loft conversions, which create large double bedrooms with en-suite bathrooms in the roof space. The stucco-fronted Victorian houses that characterise the Pembridge, Ladbroke and Stanley conservation areas have high roof ridges and steep pitches that provide excellent natural headroom. Mansard loft conversions are also popular in Notting Hill for properties where maximum space and value uplift is the priority.
