I had a customer send me a picture of a stair design they want and it seems like a fold back stair is a good starting point but I cant seem to get softplan to do what I want. The house has 9' walls and I need the stairs to angle at the top and bottom similar to the attached picture. Anyone have a suggestion?

Just a word of caution. Check your local codes to see if you are able to have two winders in a single stair run. In Canada this is not allowed. I can, however, add a landing at the top if I need to change directions again.

Code allows you to have two winders but not like that. The minimum at any edge needs to be 6" and it has to be 10" deep 12" from the corner (IRC 311.5.3.2)

That sounds like our code requirements for curved stairs. Our winders must meet at a point, be 45 or 30 degrees and cannot exceed 90 degrees of turn (1,2 or 3 @ 30 - 1 or 2 @ 45)

in Florida, same thing....I stay away from that kind of stair design at ALL costs.
Too hard to achieve with that 6" min. tread depth requirement.

I just read your stairs codes (IRC 311.5.3.2) and that sure does make it difficult to build winders. In the event you are ever working on a project for a Canadian client here is our code covering the subject

Tim-not to get into an ethics discussion but I have a saying that I follow "Construct today what you want of yourself in 15 years". I have people in the past who have asked me to create bedrooms without proper egress windows. Tread lightly (no pun intended)

In this day and age we have become a society of litigants. It is not a good idea to produce a set of plans that knowingly circumvent building codes and or municipal bylaws. I am a firm believer that if you leave your ass out in the breeze often enough somebody is going to kick it!

First, I agree with everything that has been said in this thread. And Tim, you made the right decision.
In Massachusetts, we have amended the 6 inch minimum tread depth to 3 inches, allowing a little more flexibility while not really impacting life safety. As a Mass. code official, I can tell you that building inspectors DO look carefully at this sort of thing when we do plan reviews. A good rule to live by is: Don't try to cheat or short-cut, or eventually you'll be sorry.
