You are facing a glass door in the wash room. Slightly move towards your left and leave the wash room and walk straightly till you reach the brown big lockers at the end of the room. Take a right turn and walk all the way up the stairs. Then to your left you will find an open door which leads to out of the house. Move towards it. After coming out of that door, move towards the grilled door and in front of that door will be the final destination.
