This spiral stair is a project we worked on in the Tahoe area. It was challenging to get the stair to marry up with the stone wall around the outside and to get rotation/headroom to fit. But, between our team and the homeowners, we came up with a plan to secure the treads to the wall behind the stone and implemented landings to make the rotation functional and appealing. We spent a lot of time discussing and sending sketches back and forth to arrive at this design, which complemented the main stair by using similar elements and also bringing new ones into the balustrade design.
