The rehabilitation of Mayo Hall calls for the demolition of non-historic additions to make way for a new modern single-story addition. Mayo Hall faces Morrow Cove and the greater San Francisco Bay, which offers incredible opportunities for views out to the Bay and bringing light and air into the new building. The interior layout is organized around a main circulation space dubbed “The Concourse” from which all the different programs for student life and cadet services are connected. The existing gymnasium houses two large multi-purpose conference rooms and student leadership and career services in an open loft-like second floor. The existing natatorium  remains relatively open and active, housing the student life and bistro spaces. The Health Services department occupies the North side addition with its own separate and discrete entrance, providing a truly new health services building. Admissions, registrar and financial aid departments inhabit the other addition. Mayo Hall emphasizes shared, cultural spaces such as the Wall of Honor, gallery to display Cal Maritime relics, and impromptu spill-out spaces that are critical for meeting and conference room functions. These spaces not only display the shared history of California Maritime and its alumni, but also act as a recruitment tool for attracting future cadets to campus.
