Its long shape and central position make Wu Hall a visual hyphen that connects the dormitories and unites them. Brick walls, limestone trim and strip windows adhere to the traditional Gothic architecture of Princeton. The main entrance, set off-center and broadside in the building, is marked by a bold marble and gray granite panel recalling early Renaissance ornament and symbolizing the entrance to the College as a whole as well as to the building itself. Inside, the long dining room recalls the English Gothic halls traditional to Princeton. Two-story bay windows at each end of the building create a spaciousness and scale typical of historical prototypes, and admit lots of cheerful light.
Furnishings chosen by the architects create intimate detail and promote comfort.
To the left of the lobby, a stair rises by a bay window to a lounge. From the lounge, a hall leads past offices to a library study area. The lounge and the library each include one of the large bay windows, visually expanding their relatively small spaces. Both inside and outside spaces have been designed to provide opportunities for informal and spontaneous interaction among students. The stairway itself serves several purposes.
