Microsoft – 677 Fifth Avenue

New York, NY

This retail renovation involved the removal of several building columns between the cellar and fourth floors along with creation of a new feature stair, insertion of a new elevator and replacement of the facade with new cable-net wall.  The C-shaped stair uses three short flights and two landings between floor levels. It is constructed from hollow steel tube sections, extends from ground to third floor and is supported at each floor and with two vertical tube posts on the back side of the middle flight of steps.
