Yeo Hall Mess Building, Kingston

Yeo Hall Mess Building, also known as Building No. 32, is a prominent structure located on the west border of the parade square. This austere, rectangular building is faced with rusticated limestone, giving it a robust and timeless appearance. The main façade features a distinct shaped, parapeted central gable that rises above a two-storey bay, contributing to its commanding presence. The building's designation is confined to its footprint, emphasizing its historical and architectural significance within the college grounds.

The Yeo Hall Mess Building holds a special place in Canadian military history as it is closely associated with the emergence of a professional armed force through officer training. Constructed during the Great Depression, the building campaign that included Yeo Hall was part of an effort to establish a uniform architectural style at RMC. Despite the general fiscal restraint of the time, this construction effort underscored the importance of military education and the development of a professional military officer corps in Canada.

Architecturally, Yeo Hall Mess Building is an excellent example of the Collegiate Gothic style that became the standard at RMC at the turn of the century. This style is characterized by its axial symmetry, consistency of style and materials, and adherence to Beaux-Arts principles, which emphasize functional efficiency, expandable design, and unity of form. The building's design and craftsmanship reflect the high standards of construction and aesthetic quality that were maintained even during economically challenging times.
