Local risks

Why Totteridge houses move

Larger gardens mean more tree roots, longer drains, and heavier boundary walls pressing down on shrinking clay.

  • Mature garden trees Roots draw moisture from the clay directly beneath the foundations.
  • Private drainage runs Long pipe runs across large gardens can leak and soften the ground.
  • Heavy boundary walls Brick walls settle independently and pull away from the main house.
  • Dollis valley slopes Ground near the brook shifts as water levels rise and fall.
  • London clay subsoil The clay shrinks in dry summers and swells after winter rain.
