Its a bit inspired from Divergent as I was thinking about BB being like the Hunger Games this upcoming series and thought of other books/films it could be inspired by!
this is an Idea for a future BB! On launch 15 housemates enter however there are 3 areas to the house, 3 houses, each has their own small garden and each fraction has 5 housemates. The fraction Theme won't be revealed till a few days before launch, and will be a big surprise to housemates on launch. When they enter, there will be 3 doors, each housemate will walk into the door thats lit up. When nominations come each week it depends on how many tasks each fraction has won. The winning fraction has no housemates up, and the runner up puts 1 up with the looser putting 2 housemates up. Food is giving out also according to how many task each fraction has won. But the main twist is that when a housemate gets evicted they go to another secret house (Built off site to the main studio) were they live in quite bad conditions. When it gets to the final week, and all fraction have 1 housemate left, and 2 have 2. And the big twist is all the evicted housemates return (9) return as a team, meaning the the other 3 fractions join together (5) and battle off in many tasks, but the main house group gets slightly easier tasks due to theirs short numbers. Which ever team win then stays in the house and the others are all evicted. But only 4 can remain meaning if the evicted housemates fraction win they will have to fight off until 4 remain. The final would be as normal with 4 housemates being evicted.
Evictions throughout the series until the big conclusion are as normal as housemates inside the house have no idea about the outside fraction were all the evicted housemates are.
The main twist would be able to run throughout the series as it concludes and is revealed at the end of the series. It might be a risk as it could be boring, as not all the housemates are living together.
Instead of being like 'Power' and housemates mainly fighting for themselves, its more about teams.
Thoughts?
