Returning for a fourth series, this nine-part contest is not for the faint-hearted! Architecture historian Tom Dyckhoff presents, with judges Daniel Hopwood and Kelly Hoppen scrutinising the contestants’ every move.

In the first round of the first heat, amateur designers Daniela, Oliver and Katie are in Cheltenham, each with 48 hours, £1,000 and a small team to transform a room in Regency homes on the Pittville estate.

Will Daniela’s modern, tropical vision for a 12-year-old’s bedroom dazzle? Can Oliver’s ‘mash-up’ style turn a boring basement into a haven? And will Katie’s unwavering commitment to ‘bringing back peach’ cause her clients consternation? Continues tomorrow.
