Before we meet our new Houseguests, it’s time to tour their new home. Though the layout may be the same, the house has been refitted to reflect the theme of the season. With a reception area featuring a wall of 75 keys, an attic bedroom of oddities, and a secretive “wine cellar,“Houseguests have more room than ever to scheme and plot as they hope to earn power and safety.

Attic Bedroom of Oddities: Beds made from wooden crates, rubber masks on the walls and haunted artifacts like a black knight’s helmet and diving suit make this room a spooky treasure trove.

Sleeper Car Bunk Room: Behind a secret entrance, this train-themed bedroom straight out of a murder mystery novel contains bunk beds for six Houseguests (the first time theBig Brotherhouse has had bunk beds since season one!) and a sleek Art Deco design.

Rooftop Garden Kitchen: The kitchen and dining area mimic a rooftop garden with ivy-covered walls, sunset skies and a 10-foot round garden party table under string lights.

Secretive “Wine Cellar”: A moody, bottle-lined cellar (with no actual wine, sorry Houseguests) is a perfect spot for whispering secrets and plotting moves.

Victorian Conservatory Lounge: A lush, plant-filled room with a 13-foot green velvet lounge and a plum tree, ideal for quiet strategy sessions.

Venom Lounge and Poison Bar: Upstairs, snakes slither across the wallpaper in a moody lounge featuring a “Poison Bar,” (don’t worry, there is no actual poison) a velvet daybed and ravens stealing party lights.

Boxing Ring Gym: The gym includes a full boxing ring, heavy bag, and workout gear – great for blowing off steam and staying in top sleuthing shape.
