Permitted Development (PD) allows certain home improvements without full planning permission — but only if strict rules are followed.
Why PD Drawings Still Matter
Even where planning permission is not required, you still need:
Accurate PD-compliant drawings
Confirmation of volume, height, and boundary rules
Clear documentation for builders and Building Control
Many homeowners also apply for a Lawful Development Certificate to formally confirm compliance.
Online PD drawings reduce risk and protect future property value.
