Stuart and Scarlette Douglas have been working together for years, and have overseen hundreds of house renovations. The brother and sister teamed up for Channel 4's Worst House on the Street in 2021 and Can't Sell, Must Sell, which was recently renewed for a second series. The siblings are joining forces once again for their latest venture, Keys or Coffee, in which one member of the public can win a brand new house for the price of a coffee. Their new social media project will have a life-changing impact on one lucky person – but that's nothing new to the presenters.
While filming Worst House on the Street, Stuart and Scarlette met newly-weds Ben and Millie, who were hoping to turn their derelict house into their dream forever home. It was a renovation project that the siblings will always remember, given the emotional circumstances surrounding the family.

After meeting the couple's family, they discovered that Ben's dad was unwell. "We were trying to make sure, or help them get the renovation finished so that Ben's dad would be able to see it," Stuary exclusively told Express Online.
Thankfully, Ben's dad saw his son's completed home. "When that renovation was finished and Ben's dad was able to be there and experience it, that was really, really special," the 47-year-old said.
Scarlette added: "It was quite a long renovation – maybe a year and a half - and then it was maybe another year and a half until the show actually came out so we were hoping that not only was he going to see the end product, but actually get to see the show.
"And he did make it. That, not just for Ben and Millie and for their dad, but for us, the crew, for everybody involved in that show, we were just willing for it to be right and be done for this guy to see it and he did. That was a really beautiful moment."

Stuart admitted: "That surpasses any renovation or any transformation. For me, that was probably the most heartfelt, emotional episode because of the reasons that surrounded it."
Scarlette agreed, adding: "They even had a baby as well throughout that time. They were pregnant when they started and by the time we'd finished there was a baby. You've got everything in that show."
The Channel 4 hosts launched Keys or Coffee in December 2025, in the hopes of making home ownership "accessible, meaningful and exciting".
Explaining how the project came about, Stuart said: "We've always wanted to get the public involved and it's very difficult. We always renovate properties off camera anyways, so we thought we'd let the public decide what goes into the property.
"Then it just grew. We're going to let the public decide what goes in it. Should we let someone in the public win it? And then we thought, 'Why not?' It's not something that we've done before.
"We normally sell properties the traditional way. Whereas this time we changed it. Once it's been designed by the nation, somebody can win it."
On Instagram, the public are invited to choose between three design options for different parts of the property, covering everything from doors and flooring to kitchens, worktops and bathroom styles.
Whichever option receives the most votes is the one that will be installed inside the home. Scarlette branded it "the house social media built" and highlighted that this process means every finished house will feel different and unique.
The I'm A Celebrity star said: "It really is the house that social media built. I think it's brilliant because as much as I maybe would have chosen option A and Stuart option B, option C has won it. What's great is that there are so many different options so one house is never going to be the same. It's always going to be different and unique."
Members of the public can enter the draw to win the property, located in Bournemouth, for just £3 – the average price of a coffee.
There are also bundles available priced at £20 and £90, with a trip to Rio for two with a coffee tour and a separate prize of £5,000 up for grabs.
The winner of the property, and the other prizes, will be announced on April 19 at the Ideal Home Show.
