The Boss's Office is the main office where Stanley's boss works.
The room features a red, floral wallpaper on all sides, a piano on the left, a bookshelf adjacent to the piano, several photographs and paintings on the far end by the desk, more bookshelves on the far end of the left and right wall, a couch and sitting chairs accompanied by a table, a desk and computer for the boss, the keypad for the Mind Control Facility and a fake fireplace that leads to the aforementioned location.In the original Half-Life 2 mod, the office features a computer desk for the boss, several cabinets, and the keypad to the Mind Control Facility hidden behind a sole cabinet. This room version is significantly smaller than the HD Remix version. In the Not Stanley Ending, the Boss's Office features a green wallpaper, a single computer desk for the boss, paintings, two bookshelves on the left and the right of the desk, and a door with a voice receiver instead of the default keypad.
The Escape Pod Ending occurs here after Stanley quickly exits out the double doors to the office as they close.
