The four-part series is fronted by multi award-winning rapper Tinie Tempah, who has an extensive property portfolio and is no stranger to the complex trials and tribulations of home renovation.

The series will follow Brits embarking on some of the most eye-wateringly expensive extensions across the UK. The typical cost of extending a property ranges from £16k to £55k but the extensions in this series these aren’t your average side-returns, they are year-long builds with million-pound budgets.

Viewers will join the homeowners as they attempt to see their super extension brought to life. Expect design dramas, scheduling crises, budgetary surprises and relationship challenges on the path to revealing the (hopefully) finished article in all its glory.

They’ll be helped along the way by Tinie who shares his personal renovation experiences and offers practical and design guidance on their way to building the extensions of their dreams.

Tinie Tempah comments: “I've always been really into architecture and design and have been lucky to witness and be a part of some amazing projects. I can't wait to see how these ambitious homeowners give their properties a 21st century shake up with the most extraordinary extensions”

Clemency Green, Commissioning Editor for Features at Channel 4 said, “This series is a whole new level of jaw dropping home renovation. We’re delighted to be working with Avalon and Tinie as we take an eye-opening look around some truly Outrageous Extensions.”
