I’m trying to design some stairs. They are from the basement to the cellar. You enter on the side and it spirrals to the right 90 degrees then follows the wall down. Once it reaches the cellar floor it spirals to the right again 45 degrees.

Below is a diagram of it. The cool thing about the stairs is that the treads and risers are old railroad logs. The treads are going to be oak. The risers are going to be a mixture of all kinds of hardwood. Hopefully it will look good as well as show the great variety of salvaged wood available. I’m getting it from M Fine Lumber in Williamsburg.
(note: we changed our plans and didn’t do this design)
