This is a great option for people who dont have too much space in their offices or house for a regular long stair... you can save at least the half of the space without the problems of having smaller steps... 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.
Let's get it on!

Step 1: Our Problem.

We have an office in an old building in Monterrey, Mexico, and we pay a rent of only $150 US at month, so is very cheap, but is not a big space... maybe 8m x 4m with two gigant windows in the front in one of the 8m sides, and the door is on the 4m side... so is a very small space but is very good ventilated and we are right in the downtown. So our first step was build a second floor with 3/4" plywood and a lot of wood beams and steel columns... so we need a strong stair but we can't use a lot of space. And my partner remember a desing that he saw back in his school days and in a lot of european magazzines: a Right foot stair.
<p>Do you think the premise of these stairs could be build to be used as an unfolding attic stairway? I've got to get a safer way up to that area after falling off a ladder. And a standard pull down ladder isn't the way I want to go. I'd like to be able to descend from the attic forward facing and I don't really have the space to do much more than this anyway. Anyone ever build an attic pulldown stairway?</p>
I&acute;m pretty sure it may work... maybe you can take the mechanical parts of a regular pull down ladder and adapt this design... I think the problem will be about the space you need... the size may be as much as the double compared to a regular pull down ladder... so you have to make sure the hole in the roof must have the right space.<br>Instead of having steps of 4 inches...like in a regular pull down ladder... you need at least 8 inches for this design to work safely.<br><br>Hope you try it!
Can't it be dangerous? especially when sleepy?
I guess maybe... but you get use to really fast...<br>we use it all the time... and even kids use it...<br>
I must say that it's an example of good designing.
This was made by the Brazilian inventor Santos Dumont, in the early 1900s.<br>http://www.youtube.com/watch?v=9ai2v2xzDgc&amp;NR=1

I love it! I just built something like it. Look for &quot;Single Step Stairs&quot; but it is only four steps. Great job.
thank you!!!
Good work. FYI- They are called Alternating Tread Stairs.
It&acute;s a great solution... need some work... but its very effective!! good luck!
these will work well in my new shop to save floor space :)
