Regarding Osler Building. Excerpts from the National Register nomination:
The U-shaped Osler Building was constructed in three phases: the first three floors in 1928, floors four to six in 1929, and a partial seventh floor, set back from the west (front) elevation was added in c. 1946.
The Osler Building is an excellent example of the Mission/Spanish Colonial Revival on an office building, and was designed by Hawk and Parr, one of Oklahoma Citys prominent architectural firms during the first half of the twentieth century.
The Osler Building was constructed by the Physicians Holding Company in 1928. Before this first suburban medical office building was constructed, most doctors had offices in various downtown office buildings or in the Classical Revival style Medical Arts Building at 100 Park Avenue. With car ownership quickly spreading in the 1920s, it became increasingly difficult for patients to find parking downtown. Also four hospitals were located in the Midtown area, just ten blocks north of the business district The Osler Building could not have been better located amid these hospitals and near the medical school where physicians had ready access to all of them. Perhaps one of the Oslers greatest assets was available parking; a lure for those trying to avoid the congested downtown.
