George looks back at some innovative and eccentric builds, from a tiny Italian tuk tuk campervan to an Airstream party pad and a trailer caravan clad in old CDs.

As George Clarke completes his review of five years of Amazing Spaces, he reflects on the incredible things it's possible to build in the humble back garden: from a cliff-top stargazing retreat to a glorious garden room made from a derelict swimming pool, and the country's most multi-functional shed. George also looks back on his own garden build, where he and Will Hardie transformed his knackered old garage and unloved lawn into the ultimate garden family studio.
