Kitchen Designer vs Self-Sourcing: Which Route Is Right for Your Extension?

The most expensive kitchen mistake on an extension project has nothing to do with worktop materials or handle styles. It's leaving the kitchen design until the extension is "nearly finished" and then discovering your electrician has already wired sockets in the wrong places, your plumber has routed waste pipes to a wall that's now a window, and your extractor duct punches through the ceiling exactly where your wall units need to go.

That rework costs thousands. And it's completely avoidable if you make one decision at the right time: how are you going to source your kitchen?
