Alternating Tread Stairs

Alternating Tread Stairs
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 1Our problem.

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.

I must say that it's an example of good designing.

This was made by the Brazilian inventor Santos Dumont, in the early 1900s.

I love it! I just built something like it. Look for "Single Step Stairs" but it is only four steps. Great job.
