An alternating stairs design though will allow you to climb down facing forward which is impossible to do with a ladder.
Alternating stair tread design.
Stair slope of either 56 or 68 degrees requires a smaller overall footprint than a standard stair.
But with an alternating tread stair the difference in height between the right and left treads is the unit rise using the guidelines of commercially built alternating tread stairs i try to get the unit rise between 6 1 2 in.
Alternating tread stairs design offers a shorter span than traditional steps for applications where there is minimal space for installation of a traditional style stair.
The tread depth and the rise from step to step is the same as on a normal stair but because half of each tread is omitted the run is reduced by half.
Alternating tread staircases are used in small spaces because they are some of the best ways to add square footage short of using a ladder.
For spatial frugality nothing short of a ladder can compete with the alternate tread stair.
The unused half tread is removed to provide more tread depth for improved safety and comfort.
Designed to be used as a stair with users facing the direction of travel when climbing up and down.
Its a little bit dificult to make the math but is an excellent result and you can make it as elegant as you can do it.
It can also be incorporated with designs and features that will make it a lot neater.
It s as if the staircase had been compressed from front to back.
