This season, the logo is a colorful eye with a pupil that resembles a compass, filled with multiple colours. Every season, the logo of the show is changed based on a particular theme. This theme has also been incorporated in the interiors of the house.
As with the past three seasons, the house is located at EVP FILM CITY in Chennai, Tamil Nadu.
The house has been completely renovated from Season 3. Rather than warm colours from the last season, this time, the house has been fully designed in vibrant shades with gaudy lights.
Rooms/Areas in the house include the confession room, living room, kitchen, dining room, store room, two attached bedrooms (along with an attached toilet in one of the rooms), bathroom, garden with some lounging areas, swimming pool (not in use this season), gym (removed), activity room and resting room (Bigg Boss Prison).
This season stands out as the only one in the Bigg Boss Tamil franchise to forgo the 'Secret Room' feature, which had been utilized in the previous three seasons. It also marked the beginning of a trend, with the feature remaining unused in all subsequent seasons.
