Head judge Michelle Ogundehin challenges the contenders to transform upmarket rental flats in Manchester.
The designers are sent to Wotton House in Surrey, a Grade II listed grand hotel. There they must each update a bedroom in their signature style, incorporating a 'British eccentric' twist.
The remaining eight contenders work on four dated common rooms at Gordano School in Bristol, with two to be eliminated after this challenge.
The six remaining designers are set their next challenge. They are off to the cathedral city of Salisbury to transform three very different shops.
Working solo, the five remaining designers each transform a shepherd's hut on a glamping site in north Wales. The spaces are small, so practicality is key.
In teams of two, the final four designers renovate two cafes in the seaside town of Margate.
The three semi-finalists are challenged to upgrade luxury holiday lodges in the Cotswolds. They must make their mark with some design flair while keeping in the mind the target market.
Having survived seven tough challenges, the two finalists must now redesign two trendy bars in London's Soho.
