The Durant-Dort Carriage Company Office is a National Historic Landmark owned by General Motors.

A late 19th-century office building located at 316 West Water Street in Flint, Michigan, it was built and occupied by GM's parent, Durant-Dort, followed by Dort Motor Car Company, until 1924.

When built it was considered one of the finest office buildings in the country primarily because of the ornate interior.

[5] A contemporaneous account describes it as "an elegant office in connection with [the] main factory, where clerks, stenographers, and typewriters are engaged in the clerical part of the company's business.

[7] Funds were raised, and it was restored to its early 1900s condition with the hipped roof and portico of that time.
