August 29, 2025

Columbia University Facilities and Operations completed a multi-year, building-wide renovation project at 518 W. 111th Street, resulting in 32 fully renovated apartments and a fully electric building infrastructure.

The six-story building, originally built in 1909 and located within the Morningside Heights Historic District, faced significant water damage that necessitated comprehensive renovations. The building infrastructure upgrades included a building-wide replacement of the floor structures; structural work in the basement; new mechanical, electrical, and plumbing systems; and new fire protection systems.

Apartments within the building received full, gut renovations featuring new apartment layouts with new open kitchen design; accessibility improvements; new appliances including in-unit washers and dryers, plumbing and lighting fixtures; new architectural finishes; an additional ten bathrooms among the units; and central air conditioning. Historical elements of the building’s lobby and hallways were preserved while making the interior spaces modern, open, and functional.

As part of Columbia's stated commitment to achieve net zero greenhouse gas emissions by 2050 or sooner, the building was renovated to be fully electric without any fossil fuel connections, while reclaiming basement space due to the removal of the old fuel oil tank. The electrification of the building is anticipated to reduce energy consumption by 19 percent compared to ASHRAE 90.1 2010 standards.

Other notable sustainability features at the building include high efficiency HVAC systems for central air conditioning and heating; new building insulation; locally sourced and low-volatile organic compound (VOC) finishes; and new LED lighting throughout the building.  The building is currently tracking LEED® Silver certification in recognition of its sustainable design and construction elements from the U.S. Green Building Council (USGBC).

Re-occupancy at the renovated building began in late spring 2025.
