Dash Marshall Adds Stunning Curved Staircase to TriBeCa Apartment

The show-stopping staircase that corkscrews through this 3,600-square-foot New York residence does more than just unite upper and lower levels, explain Dash Marshall co-founders Ritchie Yao, Amy Yang, and Bryan Boyer. It also serves as a conceptual anchor for the project itself, which commenced shortly after Hurricane Sandy flooded parts of the surrounding TriBeCa neighborhood. The notion of rising to safe refuge is embodied by the tripartite form: the twisting curve of blackened steel (another nod to the industrial nabe) stops a few steps short of the ground-level family room, terminating instead at an oak-floored “raft”: a raised platform that houses a wet bar and hangout area. The stair’s hefty metal treads and balustrade are supported by a white-painted brick plinth as well as by slim steel rods and bronze railings that confer a feeling of levity. “We chose to suspend the stair from the ceiling as well as building up from the floor,” Yao says. In this way, adds Boyer, “materials and structural systems come together as one.”
