Sheet 09 — Location planAreas we cover
Surveys & planning across London — and beyond.
How much does a measured survey cost in London?
Every property is different, so we give a fixed quote once we know the address and what you need drawn.
How long does planning permission take?
Councils aim to decide most householder and minor applications within 8 weeks of validation, and major ones within 13.
Do I need planning for a rear extension?
Not always — many fall under permitted development. An LDC confirms it in writing before you build.
What’s included in a measured survey?
Accurate existing floor plans, plus elevations and sections where needed.
LDC or planning permission — which do I need?
If your work is permitted development, an LDC is usually enough. If not, you’ll need planning permission. We’ll tell you on the first call.
