Extraordinary Extensions - Season 1

Tinie checks out Amy and Simon's million-pound glass structure by the sea in Hampshire, and Alan and Lynda's multigenerational living under a bold, angular ski slope roof in Herefordshire

Tinie meets a couple who are building an enormous subterranean extension on their Grade II listed gate lodge, and visits an £11 million mega-basement in Knightsbridge.

Tinie Tempah follows two builds that sit uniquely in their surroundings, meeting contractor Rod and his gin distiller wife Clarice, who have added a modern and uncompromising 21st-century extension to their 17th-century Cotswolds cottage. Tinie also follows passionate extenders NHS surgeon Humza and his banker wife Pari, who indulge their creative flair, attention to detail and love of terrazzo with a unique up-and-over arch window.

Tinie Tempah follows the pioneering reinvention of a Victorian building in south London. Architect Richard and his writer wife Eva are converting their 19th-century former timber yard from an office into a family home for themselves and their two children. Key to the design are the cutting-edge innovations to achieve ultra-low energy use, making this the only passive house that has been built by converting a commercial space.
