Tinie Tempah follows more homeowners as they build awe-inspiring extensions. In Warwickshire, Tinie follows a couple taking on a million-pound retirement project of adding an underground swimming pool and spa extension to their curved mega-home.

In Peckham, Tinie joins an entrepreneur as he lets a graffiti artist and a massive living jungle-wall take over his Victorian house. And a couple with a fraction of a budget attempt to extend their distinctive 1960's Essex home without ruining it.
