The wait is over! Big Brother 27 premieres Thursday, July 10, 2025, on CBS with a thrilling new theme: Hotel Mystère. This season promises a suspense-filled ride full of secrets, twists, and unexpected visitors, all set inside a lavish, mysterious hotel-themed house. Nicknamed the “Summer of Mystery,” BB27 is celebrating 25 years of Big Brother USA with its most interactive, immersive game yet.
Inside the Big Brother 27 House: Welcome to Hotel Mystère
This year’s house isn’t just a backdrop—it’s a character in the game. Inspired by old-world mystery hotels and full of shadowy corners and secret clues, the BB27 house is designed to mess with the minds of the houseguests—and viewers.
Here’s what’s inside:
-
Reception Room: A dramatic wall of 75 key boxes—some of which unlock twists and hidden powers.
-
Chessboard Living Room: Strategically placed black-and-white décor sets the tone for a season of mental warfare.
-
Rooftop Garden Kitchen: Ivy-covered walls and hanging lights create a calm (but not for long) meeting space.
-
Wine Cellar Lounge: Perfect for hushed strategy talks and nighttime whisper alliances.
-
Venom Lounge & Poison Bar: Dark, moody, and covered in snakes—this might be the spookiest hangout ever.
-
Victorian Conservatory: A plant-filled velvet retreat for quiet chats or unexpected blowups.
-
Attic of Oddities: Think haunted hotel meets curiosity shop, with crate beds and creepy trinkets.
-
Sleeper Car Bedroom: Designed like a luxury train compartment—tight quarters mean tight alliances.
-
Boxing Ring Gym: Let the physical (and social) battles begin.
