As the countdown to Big Brother 27 continues, production is shifting into high gear behind the scenes. With the season premiere set for July 10, fans are eager to know when the houseguests will go into seclusion and when CBS will finally unveil the look of the brand-new BB house. Here’s everything we know so far.
When Will the Houseguests Be Sequestered?
Reliable sources within the fan community including longtime followers like Big Brother Gossip on Bluesky report that this year’s houseguests will be entering sequester over the weekend preceding the July 10 premiere. That would place their isolation start date around June 8–9, giving them just under two weeks off-grid before they walk through the front door and begin competing.
Sequester is a long-running part of the Big Brother pre-season process. During this time, houseguests are completely cut off from the outside world. No phones, no social media, and no news, not even access to each other. The purpose is to protect the integrity of the game, limit leaks, and allow contestants to focus entirely on the upcoming competition.
While CBS has not officially confirmed this year’s sequester schedule, the timing lines up with past seasons. Historically, contestants enter isolation about 10 to 14 days prior to premiere, during which time they may undergo final medical and psychological evaluations, orientation briefings, and interviews with production.
When Will the New Big Brother House Be Revealed?
Fans are also keeping their eyes peeled for the first images and videos of the BB27 house a highlight that typically arrives shortly before the game begins. Based on the release pattern in previous years, the house design is likely to be revealed sometime during the first week of July.
House tours are usually led by host Julie Chen Moonves and often drop just a few days before the cast reveal. These sneak peeks give viewers their first impression of the season’s theme, color palette, room layouts, and any twist-related design elements.
In recent seasons, the Big Brother house design has matched each theme—from the camp-inspired living spaces in Season 21, to the mid-century ‘BB Motel’ in Season 24, and the AI-driven tech layout of Season 26. CBS hasn’t released official visuals for Season 27 yet, but the promotional ‘key art,’ social media hints, and insider Reddit speculation suggest the new house may embrace a sleek, modern look — possibly with updated Head-of-House, backyard, and diary room spaces.
CBS tends to announce the official cast lineup about 4 to 7 days before the premiere — meaning fans can expect the full list of houseguests in the first or second week of July.
From there, CBS usually releases the house tour, press interviews, and digital content like “Meet the Cast” videos. These previews help set the stage for the opening night and give superfans an edge in picking early favorites or predicting alliance dynamics.
This year’s premiere episode will air on Thursday, July 10, and marks the beginning of what’s shaping up to be one of the biggest Big Brother seasons yet. Extended episodes, an “Unlocked” Friday night spinoff, and the return of weekly 90-minute airings all point to a summer packed with drama, strategy, and surprises.
The pieces are falling into place. As sequester begins this weekend and house visuals roll out next week, Big Brother 27 is officially entering its hype season.
