2. Surrey + Twickenham

Tinie Tempah meets a couple who have gambled £3.5 million to turn their Surrey home into a Marbella-inspired luxury party resort - complete with dance floor, pool house, wellness space, firepit and outdoor kitchen. Tinie also catches up with a couple with a fraction of the budget, who are trying to bring a taste of experimental Chinese timber architecture to their terraced home in south-west London.

3. Canterbury + Nottingham

Tinie Tempah follows a couple as they renovate an old Canterbury B&B by adding an extension that uses a mix of styles inspired by their Korean and Norwegian heritage. But the discovery of a Second World War bomb shelter in their back garden adds a surprise element to the project. He also follows a Miss Vintage UK finalist who fantasises about turning her Nottingham dormer bungalow into a 1960s Hollywood time capsule.

4. Croydon + Greater Manchester

Tinie Tempah meets a Croydon couple who are building the barn extension of their dreams, inspired by their passions for cars and crafts. He also revisits a Victorian property in Manchester featured in the last series, to see whether its glass box extension has been a success after years of construction drama.
