Leverett House is one of twelve undergraduate residential Houses 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.

When Leverett House opened in 1931, it originally occupied two buildings: McKinlock Hall and Stone Hall, which Quincy House now occupies and to which students often refer, perhaps misleadingly, as "Old Quincy." Today, House's facilities currently consists of three main residential buildings, McKinlock Hall, F-Tower, and G-Tower; a subsidiary building housing the House Library and building services; and several apartment suites annexed from the former DeWolfe graduate housing.

The bulk of McKinlock Hall consists of 5 entryways (labeled A through E), each of which leads to four or five floors of suites for approximately 35 students. Prior to McKinlock's 2014 renovations, each of these entryways was centered around a single stairwell, accessible only from a single door—the "entryway"—on the exterior of the building. This is the predominant arrangement of Harvard dormitories prior to the mid-20th century. The 2014 renovation replaced the entryway arrangement with a more typical hallway arrangement.

McKinlock Hall's oval window belongs to the Iliad Suite, named for an anonymous donor. This suite, highly coveted amongst Leverett seniors, is awarded to the “Most Attractive” group of rising seniors selected during a House-wide popular vote. Historically, the suite was awarded to the winners of a House-wide wet t-shirt contest, a practice banned in the early 2010s due to protests from female students that began after Radcliffe College's full incorporation into Harvard College. McKinlock also houses the Leverett Dining Hall, the Junior and Senior Common Rooms, the Old Library Theatre, the Faculty Dean's Residence, and several other common spaces.

The Leverett Towers (commonly referred to as F- and G-Tower, corresponding to their respective entryway labels) serve a primarily residential function. Each tower consists primarily of singles and doubles and holds approximately 150 students. The top floors of the towers - especially those facing south - boast outstanding views of the Boston skyline and the Charles River.

The ground floor of G-Tower features a common area called "G-Hutch." Like the Iliad Suite's wet t-shirt contest, protests from female students led to the renaming of G-Hutch from a similar, but more inappropriate name. G-Tower has been historically associated with small-scale, all-male group sexual encounters. The reason for this association has sparked ample debate; although the most well-evidenced and most likely reason for this association is the actual occurrence of such events, some alumni have suggested that this name may simply be the pun "Or-G-Tower."

The ground floor of F-tower includes a common area similar to the one found in G-Tower, as well as several offices belonging to the Allston Burr Resident Dean and House Administrator. Between the towers and McKinlock sits the Leverett Library, which was constructed along with the towers and has won awards for its innovative design. The ground floor of the library building houses the building manager's office.

The top floors of 20 DeWolfe Street were annexed by the house in fall of 2007. Originally intended for faculty or graduate students, the DeWolfe suites are smaller apartment-style units with different amenities than those available in either McKinlock or Leverett Towers, including kitchens and a year-round HVAC system.
