The first state office building in Lansing was constructed in 1853; this was replaced with another building in 1872 and demolished the following year. By the 1910s, the state realized the need for a new office building, and funds were appropriated beginning in 1917 for a new structure. Architect Edwyn A. Bowd of Lansing was engaged to design the building, and plans were approved in 1918. Construction began in 1919, but was not completed until 1921.[2]

The building served as the state office building until the completion of the first part of a new state government complex in 1953. In 1951, a major fire caused severe damage to the building. In the reconstruction, the seventh floor was removed, leaving the remaining six. The building is now a six-story U-shaped Classical Revival structure, a seventh story having been removed after a major fire in 1951.[3] The building remains in use by the state.


The Lewis Cass Building is now a six-story (originally seven-story) U-shaped Classical Revival structure with a flat roof, with a facade of cream-colored sandstone above a granite basement. A cornice separates the second and third floors, forming a base for four-story piasters with Tuscan capitals above. An entablature with cornice runs above the pilasters. As originally built, the building had three arched entrances. After the 1951 fire, two entrances were removed, and the main entrance completely rebuilt as a projecting gray granite entryway.[2]
