There are a few things you need to decide before you begin the building task: where to place the staircase, the depth of the treads and the height of the riser and whether you want a straight stairway. In this case we wanted a straight staircase; in other words no landing until the top. That being said, we allocated space for a 48" staircase on one side of the condo. You enter through a door in the garage to walk up the stairway.
As soon as we were finished building the garage level, we needed access to the second floor and the initial access was a ladder secured to the 2 x 6 studs. Going up and down a ladder can be hazardous, so I was glad when construction of the temporary stairs began.
The picture to the left begins the staircase building process. A stringer is a foundation on which the threads and risers sit. It's the first stringer and because our staircase is over 36" wide, we needed three stingers. In the older homes treads, which is the part of the stair you step on, was around 8" or 9", but after the Arts and Crafts period the depth was increased. Our tread depth is 12" and the riser is 7" high. The increased depth makes the stairs easier to walk on.
On the right is the completed temporary staircase. The temporary stairs were made out of plywood and various other wood around the garage. They lasted several months but as you can see they are only one grade better than a ladder. Before we could proceed with anymore work on the upstairs, we needed a more sturdy staircase. The staircase pictured below is the 48" wide permanent oak staircase.

As a K&B designer I don't usually have to calculate space required for a staircase, so I just loved the challenge of this task. It brought back memories of my days in drafting classes. So much fun.
