Where we build most: North London
North London projects are designed, managed and built by Pine Grove's own team. Most of the North London towns we cover sit in three boroughs, each with its own council, conservation areas and local rules.
Every North London town we cover, borough by borough, is on our house extensions in North London page. Beyond North London, we also cover the rest of London.
