This custom set of winder stairs built in Fairbanks, Alaska occupies a 4 foot wide space starting at 95 inches.
Building winder stairs requires a good plan and can be approached using many methods.
Expert stair builder, James Pagel, making the treads from birch plywood. James likes to use 2X4’s with a 3/4″ CDX top as the rough stair in the winder. I usually build what is essentially a cabinet base that is entirely plywood.
Fitting these stairs was not as easy as easy as it looks. The walls around the stairs were neither plumb or square as is the case in many older homes. For this reason I suggest making jigs for each tread if you are building your own staircase. You will not usually have a right triangle when building winder stairs. Cutting scalene triangles for stair treads is very challenging but is also the mark of an excellent carpenter.
I love the way winders look when they are located a few steps up in staircase. It has the effect of making the stairs look mountainous (I’m not kidding).
The inside corners are really stunning up close and so precipitous. Don’t walk here.
And from the top looking down.
