The House of Glass is originally a twist that happened on the 9th season of BBB.
Back then, four potential housemates were confined in a House of Glass in the middle of a shopping mall in Rio de Janeiro. They stayed there for a couple of days until the public decided which two housemates would move to the Big Brother house and the two who received the least amount of votes were "evicted".
This is the House of Glass of BB9:
This time the four evictees of this season are going to live there for 3 or 4 days and the public will again decide which 2 will move to the main house.
Do you think this is a good idea? Would you like a twist like that on BBUK?
