Located at Elstree Studios, the pictures show the house is bigger than ever and includes a curved disco-inspired illuminated staircase, as well as an alfresco dining area in the huge garden, which houses the longest swimming pool in the show's history.
Scroll down for the first pictures of this year's Big Brother house:
The open plan house sees the staircase leading to the colourful lounge, with a modern kitchen which looks directly opposite the bathroom. The bedroom includes one large double bed.
The house also includes a sauna room for the first time. Elsewhere, the housemates can use a gym including treadmills, step-machines and other luxuries.
Celebrity Big Brother will begin Thursday, August 18 at 9pm on Channel 5, while a regular series of Big Brother starts later in the year.
