I need to build a three step winding which turns 90 degrees. Local code requires the minimum stair trend at most narrow point to be greater than or equal to 4 inches. I am planning for the step to cover a 3x3 foot area. I don't know how to frame this. Any help?

You can either call a carpenter, or use 3 ply boxes each smaller than the first.

Layout the landing on the floor & mark off your radii then make the ply boxes to the layout & total rise calcs.

Sorry that'd be a landing & 2 ply boxes wouldn't it... by the way I'm pretty sure it's 6 inches and 12 at the line of travel (section 1003.3.3.8.2) & (section 1003.3.3.2)

Thanks for the input. The angle on the inside box is what is confusing me.

NC buliding code state 4 inches.

Layout the rectangular landing, then the newel or balistrade return(where in your case the 4" will be)... take a trammel (a long straight 1x4 will suffice) and mark the line of travel the 4" inner circle & the outside circle of the landing. Place the trammel through the radii points and you'll get an initial center point for your radius. Once you have the center then you can lay out the arc & divide it equally.
