Overview

The House

The house is located in front of the ABS-CBN studios in Quezon City.

A car is used to transfer the evicted housemate from the Big Brother house to the ABS-CBN main building.

The Big Brother House is a multi-room studio designed with walls painted with pastel colors. For the housemates security and the essence of being locked away from the outside world, the garden area is covered with a camouflage-type of fabric. It also boasts of a multi-faith altar in one wall of the house (one which has a Bible, a Koran, and twelve rosaries), making the house the only Big Brother house that has a room set aside for religious purposes (although it is said that the Arab Big Brother house had prayer rooms). And although any form of communication from the outside world is banned inside the house, there is a large flat-screen television set in the living room, used for only two purposes: Airing videos Big Brother want to show to any or all housemates, especially that of the TV Mass every Sunday, and To announce the names of nominees for eviction directly to the housemates and the person evicted from the house.

To complete the set up, 26 surveillance cameras are positioned all over the house to watch the housemates' every move, including the bathroom. For modesty's sake, however, images from the bathroom will be shown if the bathroom is used for any purpose other than bathing (such as gossiping).

Housemates

The show's 12 housemates all entered during a live premiere on August 21, 2005. They were introduced in a special segment during which hosts Toni Gonzaga and Mariel Rodriguez visited their houses and asked the housemates (whose faces were pixelized) to pack up their gear, giving them a special key to signify their entry in the House.

The ages stated below are their ages at time of entry inside the Big Brother House. Origin indicates where the housemates were born or based before joining the program. Thus, August 21, 2005, is stated as Day 1.
