Beast Boy introduced the building to his fellow heroes as the headquarters of the Outsiders, complete with all kinds of equipment their team would need, like a mission room, separate rooms for everyone (including those not in the team), even an empty space reserved for a future Zeta-Tube.
Kitchen: A fully stocked kitchen and eating area, overlooking the city.
Living quarters: A number of spacious separate bedrooms above the mission room, enough for everyone including those not in the team.
Med Bay: A room filled with advanced equipment to treat injured members.
Gymnasium: A room filled with exercise equipment and serves as a training area.
Mission Room: The central area of the headquarters, with a holographic computer interface, and a secured link to Watchtower systems. When not in use, the room could double as the Outsiders' "super stylin' living space".
