What if the first person you called wasn't an architect?
In this episode of the Self Builders Podcast, Jack sits down with Charlie, who bought a tired 1,200 sq ft bungalow on an acre in Berkshire, knocked it down, and replaced it with a 4,500 sq ft three-storey ICF home that blends Georgian proportions with modern, highly energy-efficient construction.
Charlie project-managed the entire build himself over three and a half years, and he's refreshingly honest about what made it work: research, strategy, and being on site almost every single day.
He also shares the one piece of advice he repeats more than any other — get a planning consultant on board before you speak to an architect. It's a reversal of how most self builders start, and Charlie explains exactly why it changed the outcome of his project.
This episode covers:
• Why a knockdown and rebuild is often easier than finding a plot
• Why a planning consultant should come before an architect
• Using permitted development rights and a heritage consultant to get planning through
• Building on a sloping site, and why he built a retaining wall instead of a basement
• What ICF construction actually is, and why he chose it over timber frame
• The realities of project managing your own build and coordinating multiple trades
• Delivering the whole project at around £250 per square foot
• Running an all-electric home with no mains gas, and why air conditioning was his best decision
Charlie's biggest lesson? Be there.
He was away from site for just five days across the whole build, and something went wrong on every one of them. If you can't be there yourself, he says, have someone independent of your builder who can.
His other message is about pace. When a problem appears, the instinct is to fix it and crack on. Charlie's advice is to stop, step back, and consider the knock-on effects before you commit — because it's always cheaper to think now than to unpick it later.
If you're planning a knockdown and rebuild, considering ICF, weighing up an all-electric home, or wondering whether to project manage your own build, this episode is full of practical, hard-won detail from someone who has just done it.
