I need somebody with an architectural training to design my staircase for me. It needs to conform to New York City code. Are you able to find out what NYC code is? Here is the image: [login to view URL] The stairway runs from the basement to the cellar. You enter on the side and it spirals to the right 90 degrees then follows the wall down. Once it reaches the cellar floor it spirals to the right again 45 degrees. I'm not sure if the opening is large enough. If not we might be able to cut more lengthwise but only if we can't make the existing opening work. This isn't really a design issue as an engineering one to adhere to code while using the small opening. I could be wrong but the I think code says the treads need to be no narrower than 8" on the inside turn and 10" on the straight. The risers need to be 8" or at the very most 9". I just need a rough sketch with the measurements. Nothing fancy as long as I can build from it. Autocad is ideal.
