Covering New Malden
New Malden sits 9 miles south-west of London, with Surbiton 2 miles to the west and Morden 3 miles to the east.
Homes in London
London projects often mean working on period terraces with neighbours on both sides, tight access through the house and conservation area controls, so careful planning and party wall work matter as much as the build.
