Conor, I usually make camera run that actually works (and for this house I'll post some images of it); since the bedroom is at a higher elevation, those stairs are from the fire exit and down to the camera run. They're painted yellow so as to be seen in an otherwise pitch-black area becuse the mirrors don't give enough light.
From this view of the bedroom, you can not only see the front door but also the top of the house and a bit of the interview stage.
