Milstein Hall, the architecture facility at Cornell designed by OMA and Rem Koolhaas, has a “growing” handrail problem: the vines intended to cover the exterior egress stairway have penetrated the metal grid on which they’re supported, and have rendered the handrail noncompliant.
Handrails must be continuous; the NYS Building Code has this advice: “Handrail gripping surfaces shall be continuous, without interruption by newel posts or other obstructions.”
