I think the Business LLC will be housed at 650 Lincoln. This is a brand new building (2 buildings, actually) located close to the Business School and the Fitness Center. They cost more than the regular dorms but have some really nice conveniences like dishwashers, washer/dryer in unit, outdoor pools, etc.
Patterson has a great location, but is all women. My kid has friends at Green Quad who really like it there.
Sorry, I don’t have any info on International House.
