As one of London's leading design and build companies, North Star has designed a comprehensive service to simplify the process of planning and constructing your extension. This includes obtaining building regulations approval, planning permission and permitted development rights.
We cover many of the London boroughs and home counties and can set up temporary kitchen facilities so homeowners can remain living in the house throughout the build.
