Building in Radlett

What working in Radlett actually involves

Radlett and the roads around Loom Lane and Newlands Avenue carry some of the largest private houses we build. Plots are deep, budgets are serious and the brief is usually a house designed for the next twenty years rather than the next five.

Replacement dwellings dominate. Buying a modest house on a good plot and rebuilding is frequently the most reliable route to a new home in this part of Hertfordshire.

Planning

Planning policy in Radlett

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

  • Hertsmere Borough Council determines applications, and Green Belt covers the land around the village boundary.
  • Replacement dwelling policy is judged against the volume and footprint of the original house, so accurate measurement of the existing building comes first.
  • Radlett has conservation area coverage and strong local character policies on roof form, materials and boundary treatment.
  • Plot severance and building two houses where one stood is possible in places but needs careful policy testing before purchase.
  • Tree cover is significant, so surveys and root protection influence footprint and foundation design.
