Front Stairwell: 
2010 - Currently covered in purple carpet, there is a step with massive damage to the carpet. It looks like there have been many attempted fixes.
    - There is a big crack in the plaster of the north wall. I have been told by a contractor that there is no water or structural damage to that wall. The crack is due to natural settling of the house.

Rear Stairwell

2010- There is currently a system of motion sensors for the lights in this stairwell installed by Aaron Webster in the 2006-7 region of time. I don't know exactly how they are wired.
