Walk straight. Pass the two chairs on the left. Wait before you get to the double glass doors and the plant.
Walk forward with the office behind you. Stop In the doorway at the end of the hall.
Stand so the hallway with the stairs is behind you and walk down the walkway between the two rows of columns. Walk straight until you enter another passageway on the opposite side of the large open room. Stop just before entering the last room with the door leading outside.
