Building in Highgate

What working in Highgate actually involves

Highgate straddles two boroughs, which means the first question on any project is which authority determines it, because policy and basement rules differ either side of the boundary.

The work itself is renovation and reconfiguration of substantial period houses: rear extensions, lower ground floors, roof conversions and complete servicing upgrades behind a facade that must not change.

Planning policy in Highgate

The constraints we test before design begins, not after a refusal.

  • Applications fall to either Camden or Haringey depending on the exact address, and their basement and extension policies are not identical.
  • Highgate Village and surrounding streets carry extensive conservation area coverage and many listed buildings.
  • Steep topography means retaining structures, drainage design and party wall matters need early attention.
  • Article 4 directions and conservation area status remove permitted development rights in much of the area.
  • Tree cover is significant and protected, influencing footprint, foundations and access.
