Inside Out Homes

In this episode, Zac is in west London, where he hopes to prove that concrete is the perfect material for inside-out living. He meets Californians Abbey and Zahed, who want a West Coast vibe in their home in Harrogate, North Yorkshire, replacing the back wall with glass and introducing a double-height feature.

In this episode, Zac creates an inside out home in a flat with no outside space. He removes the entire roof, replacing much of it with glass, while Rosie designs oversized window boxes and fills the flat with house plants. And a mock Tudor suburban semi gets a radical overhaul when Zac creates a kitchen in the courtyard, Monty builds a garden bar, and Rosie goes tropical with a lush jungle feel.

Zac tears down a mock mansion in Surrey, replacing it with a high-performance prefab. Monty helps build its cantilevered staircase, while Rosie installs a silver birch and ferns.
