This staircase is also at Abel’s house. It is not at its original location and replaced what most would consider a ladder! The staircase is known as ‘winder’ style, that is, the stairs wind around the center post. Modern building codes require the smallest point in the winding step to be 5” so, gone are the days when you could wind around a single point. For you geometry buffs, this essentially moves the centerpoint of the layout to a point a distance away from the staircase. The inside stringer is called ‘mitered’ and the outside stringer is called ‘housed’. Traditional wedging techniques were used on the housed side. The varying stringer angles inspired the curved handrail.
