Rear extension. PD route. 14 weeks.
The client wanted a brighter kitchen-diner with a utility zone and a clean PD route to avoid planning delay.
We kept the rear projection within safe PD thresholds and documented key measurements to reduce risk.
We used a low-profile roof, detailed the drainage diversion early, and phased access to keep the street clear.
We kept the proposal within PD limits and documented compliance to reduce risk.
“They mapped the PD route clearly and kept everything on track.”
If your terrace has similar access constraints, a conservative PD‑compliant depth and early drainage checks can keep the route simple.
Do rear extensions need planning permission?
Often no, if depth and height limits are respected and there are no restrictions removing PD rights.
Is a party wall agreement required?
If you share walls or excavate near a neighbour, the Party Wall Act usually applies.
When should I apply for an LDC?
If you want certainty for resale, an LDC is a good option even when PD is likely.
