The stair was built using 98% recycled steel. The team of material suppliers and subcontractors were chosen based on their corporate ecological plan.
The Amenity Stair design concept combines six separate structures as one striking stairway expressing continuity of form, structure, and space, integrated within the public space of an apartment building. Celebrating the social areas of the 33-story tower, the stair connects the 32nd and 33rd floor amenity levels of the 265-unit apartment building, contributing to the creation of a high quality, desirable and distinctive residential project. The design is comprised of 6 separate stringer and platform components placed next to each other to create a complete stair that expresses the design intent of continuous, seamless, flowing space and a sense of connection. The structure is made from steel plate, tube, and rod. The glass handrail is made with laminated glass panels attached with stainless steel clamps. The stair treads, platforms and top rails are laid up with hickory wood. Each free-standing structural component has 8 vertical tubes supporting the platform or stringer run, and the top and bottom frame is twisted by 30 degrees for strength and visual delight. The rods supporting each tread hug the top and bottom of the tube, and extend to hold the staggered SS glass clamps. The playful use of color identifies structural elements, as well as endows the stair with its vibrancy and appeal. Platforms and stringer runs are painted gray to allow the twisted vertical elements painted in yellow to stand out in dramatic contrast. The hickory wood treads, platforms, and railings have a light gray stain wash.
