465 North Park

The dramatic centerpiece of the lobby of 465 North Park space is a sculptural plaster-and-terrazzo circular staircase, measuring 15 feet tall and 14 feet in diameter, that rises up to the mezzanine level. Featuring guardrail walls with a custom plaster finish that also wraps the underside of the form, the stair’s stark white color and smooth, seamless surface complements the interior finishes of the lobby while echoing the elegance and movement of the overall building form.

The stair walls are detailed with recessed metal handrail and LED lighting that runs the entire length of the staircase. Additionally, the stair treads and risers are made of field-fabricated, custom finish terrazzo, poured and formed in place. The successful execution of the technically complex design was achieved through extensive coordination with the architect, interior designer, structural engineer, steel fabricator, light gauge subcontractor, and multiple finish subcontractors, including Sowlat, Meccor Industries, Modern Metals, E&K of Chicago, Artisan Venetian Plaster and Amici Terrazzo.
