Can architecture help solve the housing crisis? Acclaimed London architect Peter Barber thinks it can, and he's proving it one street at a time.

Tim and Kevin head to London to meet one of Britain's most admired architects, whose award-winning work is rethinking what social and affordable housing can be.

From his remarkable King's Cross studio, where every wall is lined with hand-built architectural models, Peter explains why the best neighbourhoods aren't created by grand gestures, but by streets where people get to know each other and communities are given the chance to flourish.

Peter shares his vision for tackling one of society's biggest challenges, exploring why familiar housing forms still have so much to teach us, what we've lost in the pursuit of home ownership, and why he believes governments already know how to solve the housing crisis. They simply need the courage to act.

Thoughtful, passionate and quietly optimistic, Peter makes a compelling case that better housing isn't just possible, it's already being built.

Plus, after discovering that Kevin's lifelong musical heroes were staying in the very same hotel, Tim embarks on a mission to persuade him to say hello. It turns out even "that bloke from Grand Designs" gets starstruck.
