Graphical Construction Glossary >> stairs. >> Miscellaneous >> Stairwell Hole
Shown above is the term in the sense of the space between the outer strings of a stair. It is the space available to say hoist or pass some object without using the steps.
The term here refers to the actual hole in the floor framing that is needed to take a stair. It is governed by the width of the stair and the length required to obtain sufficient head height to the stair.
This sketch shows an "L" shaped well hole. This time the hole again closely follows the shape of the stair following it around a quarter turn landing.
In each of the two skeches above it had previously been determined that the head height was directly above riser 3.
