There are several options for sophomores on BCs campus. The most desired dorms are Vanderslice and 90 on Lower campus (near Lower Dining Hall, the Plex, and the stadium). They're suite style apartments with 3-4 double rooms, sharing a small kitchen and living room. There's also 66 and Walsh on Lower and Roncalli, Welsh, and Williams on Upper which are all freshman dorm style, with 20-30 double rooms on a floor sharing a large bathroom.
Here's a look at what a typical freshman dorm looks like. This is a room in Gonzaga on Upper campus (Cheverus, Claver, Fenwick, Xavier, Fitzpatrick, Gonzaga, Shaw, Loyola, Medeiros, and Kostka), but there's a similar set up for dorms on the Newton campus (Keyes, Hardey, Cushing, and Duchesne) as well. Usually, two roommates share a room with two twin beds, desk, and dresser with a common bathroom on each floor.
The Mods, the most competitive senior dorms on campus, are the center of the social scene. On game days the Mods are filled with alumni and students tailgating and celebrating while on the weekends they're a popular source of parties.
The Mods have been called "Temporary Housing" since the 70s. Whether or not they'll actually be torn down is up to the administration.
View of a typical freshman dorm at BC.
Overall the dorms are more spacious than other colleges I have seen, the cleaning crew is super nice and come everyday to clean hallways and hall bathrooms [not suites], and they are set up so you tend to reside in dorms near people in your year. In hall styles all doors are weighted so they close automatically unless left propped. I have always felt comfortable enough with the people in my building/floor to leave my door open [more so freshmen year than sophomore year however] FRESHMEN: [rooms are single sex, but dorms are co-ed by floor i.e. guys first floor, girls second floor, guys third floor, etc.] All freshmen dorms are hall style, no communal kitchens. All freshmen must live on campus. 60% live on Upper Campus, an area on top of the hill the main campus is situated on. This includes all the special interest housing like the healthy living floor, the Shaw Leadership Program [Shaw House], all girls dorm [Koska] and honors housing [Medeiros Hall]. This part of campus is mainly doubles with a few quads and triples thrown in, and there is a possibility of forced triples i.e. three people in a double room. This would give you a partial room and board refund, and you would still have one bed, one dresser, and one desk per person in the room. 40% live on Newton Campus, five minutes away from main campus by bus, located on the Law campus. It has its own library and dining hall, but students are required to come to main campus for their classes during the week. There are no forced triples on Newton. There are doubles, natural triples [larger than a double room], and quads. You cannot put any preference towards Newton or Upper. SOPHOMORES: Can opt for suite styles or hall styles [or off campus] based on their housing lottery numbers. Hall styles are found on College Road near Upper Campus and a select few buildings on Lower Campus [at the bottom of the hill near the T stop and the gym]. Suit styles are on Lower campus and are 6mans of 3 double rooms, and 8mans of 4 double rooms. Suites have their own bathrooms that are not cleaned by the university during the academic year. Some have kitchens/half kitchens. JUNIORS: Can opt for suite styles or hall styles or off campus housing due to the high number of people studying abroad during junior year. 4mans 6mans 8mans SENIORS: Can opt for suite styles [or off campus] or Modular Apartments [Mods]. The Mods are the most highly desired senior housing for only seniors can live there. It is gated so that during football game day and other special events, residents and students over 21 may enter and tailgate legally. No one under 21 is allowed in the Mods at those specified times.
