Leverett House is the largest (by number of students) of twelve residence houses for upperclass undergraduates (who have already completed their first year) at Harvard University. It is situated along the north bank of the Charles River in Cambridge and consists of McKinlock Hall, constructed in 1925, two 12-story towers completed in 1960, and two floors of 20 DeWolfe Street, a building Leverett shares with two other houses at Harvard.
