You are facing towards the closed white door. Turn to your right and move forward. You will find an open white door onto your left side. Pass through that door and take a slight right towards the open entrance on your right side. Enter through it and turn around and move towards the pathway. Now, take left where you can find a staircase. Move forward and take the first stair and that will be your end point on the first step and facing the windows on your left side.
