As part of The Great British Property Scandal season Kevin McCloud embarks on an epic battle to build his very own Grand Design. Britain needs more homes, but fed up with the poor quality of the country's identikit new houses, Kevin aims to prove that it wouldn't cost any more to build homes that are a lot nicer to live in. This first episode of the two-part series follows Kevin over five years as he sets out to prove that we can all have beautiful, affordable eco homes for the same price as low-cost social housing. Despite spending a decade watching other people build their own homes, Kevin has never built anything before. And it doesn't take long to hit all the same obstacles as everyone else - but this time it's personal.
