New Builds & Extensions in Barnet
New build homes and larger extensions for homeowners across Barnet and North London.
Trovix Group builds new build homes and house extensions for homeowners across Barnet and the wider North London area. Barnet's plots tend to be larger and more suburban than inner London, with detached and semi-detached houses that suit double-storey extensions and, on suitable plots, new build projects.
Planning treatment still varies street by street, particularly around Totteridge's more rural character and other locally protected areas, so we check each property individually rather than assuming what will be permitted. We work throughout High Barnet, New Barnet, East Barnet, Totteridge, and Whetstone.
