Schermerhorn Extension

If you’re exploring Columbia’s upper campus, the Schermerhorn Extension anchors the science quadrant. Perched behind Low Memorial Library, it holds classrooms and research hubs where intro seminars meet upper-level lab work. Beyond large lecture halls, clusters of lab benches appear between midterms and research talks, a constant buzz at the building’s stairwells when biology and earth science courses run back-to-back.

Find it tucked at 1200 Amsterdam Ave New York, NY 10027—just north of the athletic fields. Arrive early to park along the adjacent brownstone blocks or grab the 1-Train to 116th if subway traffic is light. Inside, no visitor desk checks names; simply head to whichever wing matches your recitation roster before the timer starts. Need to confirm a lab lockout or find a professor’s office? Weave (212) 854-2222 into your voice-dial list before the next quiz and double-check directions on the map.
