Here's a look at construction of Big Brother UK's new house over the past few months.
A planning application for the huge extension to the set was made back in January and permission was granted in March.
It's the biggest change to the BBUK house since it moved to its current home in Elstree Studios more than a decade ago.
Originally it wasn't clear just what the new house would be used for, with rumours suggesting it could have been a so-called 'task arena'.
Now we know it'll be home to a mysterious group of people when the new series of Big Brother kicks off on Tuesday.
The so-called 'Others' will reside in the newly built house, which has its own garden, where they will plot to take down the housemates living in the main house.
However neither group is aware of connections between them that will provide many twists and turns throughout the series.
Rylan Clark-Neal teased this week: "Watch out for The Others, The Others are coming and it's not what you think.
"They're dangerous, that's all I'm going to say. DANGER!"
He went on to reveal: "There might be a few familiar faces in there, you never know."
Of course us viewers will be in the ultimate control as one contestant ends the show with a £100,000 prize.
Big Brother 2016 begins Tuesday, June 7 at 9PM on Channel 5.
