Building on local homes

Surbiton is known for its Victorian and Edwardian villas, some within conservation areas, and these larger houses are well suited to rear and side extensions. New Malden and Worcester Park are largely made up of interwar semis and terraces, which work well for loft conversions and kitchen extensions. Worcester Park falls across more than one council area, so it is worth confirming which council covers your road.
