“BIG BROTHER: A Summer of Mystery” House Highlights:

🕵️‍♂️Mystery Hotel Theme: The BIG BROTHER house is transformed into a suspense-filled hotel, complete with secrets, hidden passageways, and a mysterious vibe that sets the stage for a summer of intrigue.

🗝️Reception Area: Houseguests are welcomed by a wall of 75 key boxes, some filled with skeleton keys and other clues that might reveal themselves later in the game …

♟️Living Room Chess Guardians: Towering 22-foot walls and a balcony lined with giant plaster chess pieces (bishop, queen, king, knight) watch over the house, adding a regal and strategic flair.

🧳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 bunkbeds for six Houseguests (the first time the BB house 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.
