Kitchen Extension specialists across Enfield.
We deliver kitchen extension projects across the full Enfield postcode set — N9, N11, N13, N14, N18, N21, EN1, EN2, EN3. North London borough with semis and bungalows suited to loft and wraparound extensions.
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 Enfield 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.
