Sarah M.
Rear Extension • Birmingham
"NeedPlanning saved us weeks of confusion about our rear extension. We got a clear answer in minutes and shared the PDF with our builder the same day."
James T.
Loft Conversion • Bristol
"I recommend NeedPlanning to clients before our first meeting. It helps them understand permitted development rules in plain English before we dive into the detail."
Rebecca L.
Garden Room • Manchester
"NeedPlanning told us our garden room likely didn't need full planning permission. That gave us the confidence to move forward and speak to our local council with the right questions."
