The American version of Big Brother is filmed in a custom-built house located within the Radford Studio Center (also known as CBS Studio Center) in Studio City, Los Angeles, California. This soundstage studio lot hosts the Big Brother house, where contestants live and compete, surveilled by numerous cameras and microphones 24/7. The studio has a large outdoor and indoor filming area specifically designed for the show. For the Big Brother season 27, the house was themed as Hotel Mystère and filmed on sound stage 18 within the Radford Studio Center. This location has been used for many seasons of Big Brother and is a well-known production site in LA for various TV shows and films.
In contrast, the UK version of Big Brother has been filmed in various studios including 3 Mills Studios in London, Elstree Studios in Hertfordshire, Garden Studios, and Versa Studios over different years.
For Celebrity Big Brother in the UK, the house in 2025 is located at a studio in West London, which had some renovations and updates recently.
So specifically, for the popular US Big Brother, the filming location is the Radford Studio Center in Los Angeles, California.
