Aviation Building, Historical aviation center in Miami, United States.

The Aviation Building was a three-story structure at 3240 NW 27th Avenue in unincorporated Dade County, Florida, its hotel shell left unfinished in 1927 and later fitted out with offices, classrooms, workshops, military barracks, a cafeteria, a library and a clinic. A WSR-57 radar was installed on its roof in 1959. It was demolished in May 1971.

Construction of the Fritz Hotel began in 1925 under M.R. Harrison Construction Company and was three-quarters complete by 1927, when work halted during the Great Depression; it never opened as a hotel. After ten years vacant, the shell was rented to small businesses. Embry-Riddle's Technical Division occupied the south wing in November 1940 and acquired the whole building by 1941, renaming it the Aviation Building. The National Weather Service moved in on June 1, 1958, and installed a WSR-57 radar on the roof on June 26, 1959, leaving on December 23, 1964. The building was demolished in May 1971.

The building's first use was as a temporary hen house holding up to 60,000 hens, which earned it the nickname "Million Dollar Hen House". Later, Embry-Riddle filled it with offices, classrooms, workshops, military barracks, a cafeteria, library and clinic. In April 1965 the school was packed into trucks and moved to Daytona Beach overnight.

The building no longer exists: it was demolished in May 1971 and replaced by a county juvenile detention center and courthouse. Its former site is at 3240 NW 27th Avenue, about 16 blocks east of the east end of runway 9/27 at Miami International Airport. Look for the courthouse and detention center complex to locate the spot.

During the economic hardship of the 1930s, part of the incomplete structure served as a chicken coop, earning it the odd nickname 'Million Dollar Hen House'. This unusual adaptation reflected the desperate circumstances of the period.
