Simon and the team go to Devon where camp site owner Faith wants to create a unique property using an invention of her late father's. Faith wants the B&B's rooms to have a celestial theme, and Simon and the team create some bespoke furnishing. Carpenter Ian Tsang creates a headboard based on the lunar cycle, designers Zoe Hewett and Sophie Dunn have some earth-based inspiration, and Simon creates a kitchen that mirrors the dome shape of the property.
