I have worked on many homes during my career as a carpenter, but one of my favorites was a craftsman near the capitol. The homeowners loved the Proctor and Gamble house (a historic Craftsman) and wanted stair that was similar to one in that house. The stair is shown below in mahogany.
Somewhere out there there is a digital tool that allows you to navigate around the house, I looked but could not find it. The windows are spectacular. Below is a picture of the stair we built for them, unfinished, and in oak. All the boards are bookmatched (the grain is continuous as they were cut from the same piece of wood) as they go horizontally around the stair.
