Kitchen Extension specialists across Redbridge.
We deliver kitchen extension projects across the full Redbridge postcode set — IG1, IG2, IG3, IG4, IG5, IG6, IG7, IG8. North-east borough with semis and detached homes — lofts and double-storey extensions common.
A kitchen extension combines a structural extension — side return, rear or wraparound — with a complete kitchen design and installation as a single fixed-price project. It's the most common instruction we receive across London: a homeowner who wants an open-plan kitchen-diner with garden views but doesn't want to manage a builder and a kitchen supplier separately. We handle design, consent, structural build, kitchen supply and installation start to finish. One contract, one project manager, one fixed price.
Every Redbridge project includes a free desk-based planning assessment before we quote. We know the local planning officers, party wall surveyors and approved inspectors by name.
