Print this post - Measure headspace in a staircase coming into a slopped roof.

In a 1.5 story house, I want to do the following:
- First floor, along the long wall, a quarter turn staircase to the second floor.
- First to second floor, the quarter turn staircase running perpendicular to the long wall follows more or less the roof, 7 feet below.

First floor, top view:

Code: Select all

___________

|       |/|
|        _|  ← staircase going up from top to bottom
|        _|
|         |

First-to-second floor, side view:

Code: Select all

        /\

      /    \
     /      \
    /___  __ \ ← second floor
   |       __ |
   |       __ |
   |       __ |
   |       __ |
   |__________| ← first floor
            ^
         staircase

How can I make sure that there is 7 feet of headspace at the quarter turn?

Thanks!
