Having aired for more than 15 years now, show bosses are said to be planning its biggest revamp yet.
Channel 5 confirmed earlier this month at the Broadcast Indie Summit (via BBUK24/7) that this summer would see a "relaunching" of the format.
It's set to be part of C5's wider improvement plans which have already seen new logos and branding, a new on demand service and plans for a Freeview HD channel.
Speaking last year, Channel 5's Director of Programmes Ben Frow vowed to take a look at the format and said the new series this year would be "very different"
Talking at Broadcast magazine’s Commissioning Forum event in London, he said at the time: “Big Brother 2016 is going to be very different to what you’ve seen before. I am going to take a big look at it.”
The biggest change to the new series will be a brand new house which will undergo its biggest transformation since first moving to Elstree Studios in North London a decade ago.
Planning permission was granted by the local last week for an extension to add a new garden and building to the set, as well as the construction of a new eviction studio and outdoor staging area.
While some documents have labelled the extension a 'second house', rumour has it will instead be a so-called 'task arena'.
Casting for Big Brother 2016 began last month with the full line up of housemates still in the process of being selected ahead of a launch in June.
