Columbia Knox Hall

New York, NY
Columbia University

When Columbia University took a 49-year lease on Knox Hall, a property of the Union Theological Seminary, the University brought in Helpern Architects to convert the early 20th-century Collegiate Gothic-style building from a faculty residence into 50,000 square feet of new classrooms and faculty offices.

The overhaul of Knox Hall’s infrastructure includes the replacement of lighting, HVAC, and water systems to reduce energy costs of the building by 23%. Wherever possible, recycled and regionally - purchased materials were used. The project earned LEED Gold Certification from the United States Green Building Council.

In addition to the sustainable components of the renovation, Helpern Architects designed offices and bathrooms that meet ADA standards, fire stairs, new elevators, and advanced information technology. Helpern also preserved and re-installed original fireplaces. Many of the new insulated glass windows overlook the Seminary’s landscaped courtyard.
