The building was designed by Minoru Yamasaki, the architect who also designed Goodhue Hall, the West Gym, Cowling, Olin, and the fourth floor addition to Myers Hall. (Yamasaki also designed the World Trade Center in New York.)
- Watson has seven floors, each holding about 40 students.
- Depending on the demand for housing, the corner rooms are either doubles or triples. They have only two closets, suggesting that they were intended to be doubles. However, they are sometimes converted into triples, such as during the 2002-2003 and 2005-2006 school years. As a result of a reduction in available housing due to the Evans renovation, all Watson corner rooms will be triples for at least Fall Term of 2012.
