The elegance of this magnificent Neoclassical style mansion belies the humble roots of its first owner, George H. Ulmer, the Pennsylvania-born son of a German immigrant. Ulmer came to Miles City in 1883, and by 1889 partners George Miles and Charles Strevell had added Ulmer’s name to their pioneer hardware firm. It became the largest hardware company in southeastern Montana. Helena-based architect Charles S. Haire designed the home for Ulmer and his wife, Flora, in 1902. Haire, whose talents contributed much to the local streetscape, was at that time frequently in Miles City supervising the design and construction of the Carnegie Library and the Ursuline Convent. These and the Ulmer residence showcase the architect’s fluency in the Neoclassical style. Haire’s design of this residence helped inspire a new trend in Miles City’s domestic architecture. A grand semicircular entry porch, Ionic columns, Palladian windows, and a central pediment with an inset lunette are elements characteristic of the style. Very fine detailing includes molded pilasters, a carved wreath above the main entry, paneled oak doors, and beveled glass.
