Stair

Design a stair using the Room.3dm rhino file as your work space. The stair will connect the lower level to the upper level (10'-6” vertically), and should include handrails, risers (7”), treads (10”), and some structure to support the stair. The stair can be spiral, straight, or turned, but in all cases should be 3'-0” wide, including a landing that is 4' long. Place the stair anywhere you like within the confines of the contextual geometry you've been given.
