House theme The house for the eighth season was in
Lonavala. It resembled the interior of an aircraft. After the first eviction, the house was made available to the housemates. The physical layout of the house remained mostly unchanged from the previous series. However, the house theme was changed to an Alpine chalet with wood, fur and leather furnishings.
Secret society On launch night, it was revealed that there was a place adjacent to the 'Plane crash' area known as 'The Secret Society.' Later, Deepshika, Pritam and Puneet were chosen by Bigg Boss to become cult celebrities who would live in the society in secret, away from the rest of the housemates.
