Winder stairs have “pie-shaped” steps which are substituted for a landing. This type is used when the space is not sufficient for the L stairs. If winder stairs are used, the width of the triangular steps should be sufficient at midpoint to provide a tread width equal to the regular steps.
Spiral or circular stairs
These stairs are gaining in popularity and the components are now manufactured by several companies. They may be used where little space is available. Most spiral stairs are made from steel and welded together, however, it is possible to construct them from wood.
Bertha Brickner says
It’s the matter of how you want to maximize the space of your home when placing your stairs there, and it is agreeable that spiral staircases save up a lot of space, just as how the winder stairs are known for being the common stair design.
Charles Aznable says
It really depends on your design preference if you want the L-type or the spiral ones.
