I have a customer that just sent me these images of their completed stairway. As you tell this was quite a large job. There were three stairways in total and a large balcony area (my favorite).
Love the radiused handrails.
The
balusters were predominately 1 3/4" barley twisted balusters. One stairway though alternated barley twisted balusters with tapered. The newels were either barley twisted or one of my Pottery Barn newels (modeled after an image in a Pottery Barn catalog.
