Go up the steps on the left. Go straight and then turn right into the hallway. Wait there.
Go towards the nearest stairwell. Go up the stairs, around a couple desks, and end in a short hallway between two stone pillars. You will be facing a large green vase with colorful things sticking out of it.
Go up the stairs and into the main work place. Walk along the right and pass the conference room with the window wall. Take a right after the conference room, and stop in the doorway.
