Turn right from the place where you are standing and move forward, you can see an open door to your left, exit the room through an open door and take left again, there is a staircase in-front of you, walk down the staircase till you can see a wall in-front of you with two photo frames on it, now turn back, climb the steps and take left, you can see an open door in-front of you, enter into it and take left, go near the pipe and stand, that's your end point.
