The Baird Machine Shop was built in 1928 by Kathryn Baird. She and her son, Arthur
Franklin Baird, opened the machine shop in 1929. Arthur left the business in 1931. Then,
George W. Wilson continued to operate a machine shop in the building until 1933. Various
owners continued operating machine shops on the same property until 1941.
From 1947 until 1964 the building was occupied by various industrial shops. The building
stood vacant until 1978, when it was purchased by the City of Phoenix.

Built in 1909 for Judge Frank Thomas, this neoclassical style building was moved in 1985 to Block 15 (next to Heritage Square) from the corner of 1st Avenue and Sherman Street to save the structure from demolition.

The Teeter carriage house was built in 1899 as the mule barn for the Bouvier-Teeter house. It is typical of the traditional carriage house structure, with vehicle, animal and tack storage below, and a loft for feed above. Detached carriage houses were common before garages and carports became popular.

The Silva house was built in 1900 by A.F.C. Kirchoff, a Phoenix liquor dealer, on land he purchased from Flora Rosson. The building is a good example of bungalow architecture, with neoclassical revival references. Kirchoff sold it in 1906 to Alejandro Silva, a Glendale rancher and warehouse owner.

The Bouvier-Teeter house was built in 1899 by Leon Bouvier.  It is a Pyramid Cottage style home, the simplest type of single-family dwelling during the late Victorian period, a style that is a direct predecessor of the bungalow.  Leon Bouvier was a cattleman and flour miller. Bouvier sold the home to Eliza Teeter in 1911 and she, in turn, rented the property until she moved into it in 1919.
