Covering Barnet
Barnet is about 10 miles north of London. We also cover Potters Bar (3 miles to the north), Borehamwood and Finchley.
Homes in London
Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.
