Straight talk, tidy sites, and one point of contact from start to finish.

PD or Full Planning?
Many projects in Killamarsh fall under Permitted Development, but volume can require neighbour consultation. We’ll confirm the route early, prepare drawings, and liaise with your inspector for smooth approvals.
Every extension is unique, but you’ll get a fixed-scope proposal after the design stage — clear allowances. Ready to extend in Killamarsh? Email Info@milldaleconstruction.co.uk to book your free survey.
