This was a little 8 step floating staircase installed to connect to the preexisting wooden staircase. Stairworks was contracted to do the steel stringer and steel handrail, but not the glass or timber treads. This is a smart option for a skilled builder who is confident enough to fit his or her own treads and make sure there's a high quality finish. Not every builder is confident enough to do this, but this was a high end application with high end builders, and the end result shows it!
