Olson Building

According to the Urban Redevelopment Authority, it "resembles the former ACS Building by Frank Brewer, with its orderly window openings and clay-tiled canopies at the 1st storey that are well-suited to the tropical climate."

[2] The building, which was designed by prominent architect Frank Wilmin Brewer to house six classrooms, was completed in 1928.

The building was named after Mary E. Olson, who twice served as the principal of the Methodist Girls' School.

The authority stated that it was the only building to be gazetted as it was architecturally significant, with several "unique" features such as its cross-ventilation.

Unsuccessful attempts were made by former students to persuade the authority to gazette the other buildings on the campus, which were later demolished.
