Staircase, Metal Tread, and Metal Railing Nouvel Approach

When the Nouvel staircase proved too costly to copy, DeSalvo designed an affordable version. The treads are perforated bent steel plates that appear to float on a support tube, while the railings are made from tension cables and galvanized handrails and posts. It offers a similar level of architectural impact and sense of transparency at relatively low cost (both stairways, plus a matching catwalk, came in at $6,000).  Photo 11 of 25 in Come Sail Away
