Update! I measured the stairway today, 38" wide & it is 1/2" taller than my loft floor. The loft has a 1/2" plywood floor on 24" centers right now, so it is on the weak side. So..... add stairway, add a lift to the floor to make up the difference & done!
I mentioned it to Roger & he laughed then said, 'By all means, help yourself, it's yours!" :)
The stairway salvage will begin in the morning.
