I understand what you guys are saying, but it doesn't work,it is totally wrong. You can't measure off the bottom of the landing joist to the top of the patio slab. That is meaning less. So right off the beginning you are building a big error into the drawing.
You have to remember that the upper landing is nothing more than a STEP. Who ever set the landing height had to know the rise and run of the steps, because you can't have a different rise and run from the bottom floor to the Landing than you do from the landing to the 2nd floor.
Jim, the best way to figure this is get the height from the top deck to the patio.
Divide that by 4". this gives you the total number of steps.
Get the measurement from a foot beyond the door opening in the direction of travel, to where you want to end the stairs, Divide that by the total number of steps, this gives you the length of the run of each step.
Keep in mind that you may run into a problem getting someone reputable to build these, because they are not to code and there is a real responsibility to the person who builds these if anyone is hurt, Besides that they are an unconventional type of stairs in that a series of platforms stacked one on top of the other with supporting legs to support the over length runs on the steps. Or a full length wall with ledgers fastened to the house and the inside of the wall to support the long steps plus the railings on both sides.
Drawing things and building things are two different things, sometimes there are no there over there.
