Situated in Olympia City, PHASe headquarters are only accessible to PHASe employees and is the home of the operatives. It's a huge facility with lots of windowless and maze-like corridors and elevators. It has an artificial look to it that causes a lot of operatives to miss nature and freedom because of its constricting design. Each department has different buildings which leads the members of the different branches do not see each other often.
It's a very spacious atrium with a refined style. It's luminous because of its numerous windows that give natural lighting. There are several escalators and notice board (that portrays examples of DNA, the human body, some rules, etc.) in the hall. Since it's a crossing point, its always crowded.
Hallways are a maze of similar looking corridors with no windows but a lot of doors, which are probably designed to confuse or trap intruders. The walls have panels of light blue contrasting with white and have screens that show news and updates. It's described as a "cold" place "where it doesn't feel like you're going anywhere", and where one cannot tell how time passes. Though its probably in all PHASe's rooms, there are speakers and an alarm in the corridors.
Like most of PHASe HQ location, Seven's Room has a refined style with white walls and a big window. It has a PHASe wall interface (with high-security clearance information), a computer, a tablet and a couple of books.
The Lounge is composed of the bar area, a lone piano and several couches and tables. It has a luxurious, high class feel to it surrounded by floor to ceiling windows that gives a beautiful view of the city. Like in the cafeteria, one can place a beverage order from the menu screen which has an extensive list of drinks but with no price. It was not mentioned on how one pays an order or whether it will be deducted from one's salary.
Also called the Lab, the Training Area is where the TCT (Team Compatibility Testing) is held. As its name indicates, we can deduce that training and other types of tests take place here.
Short for Simulation Room, here operatives can train themselves through diverse situations with the help of a visor that immerse them into different types of missions that they might encounter in real life.
