UTS Building 1, also known as the UTS Tower, is prominent landmark on Broadway at the southern gateway to Sydney's central business district. Many of the administrative units of the University of Technology, Sydney are located across the building's 27 occupied floors. Completed in 1979 in the brutalist architectural style from a 1968 plan by Michael Dysart of the NSW Government Architect's Office, the Tower was officially opened by NSW Premier Neville Wran.

The UTS Tower is located at 15 Broadway, Sydney, south of the city's central business district, near to Central Railway station and opposite One Central Park.

It sits between the UTS Bon Marche Building and Terraces (home to radio station 2SER) and the newly constructed UTS Central (Building 2).

The original 1964 plan envisaged three towers of varying heights plus a podium.^[1] By the mid-1970s, with cutbacks in commonwealth funding, the original plan was reduced to the main Tower and smaller 11-level Building 2 next door.^[2]

Construction of the building commenced in 1969 and lower floors were occupied from 1975. The building was officially opened on 15 October 1979 by the NSW Premier Neville Wran where the Tower was declared the tallest educational facility in Australia at the time.^[3] The adjoining Building 2 opened in 1980.

Originally occupied by the NSW Institute of Technology, the Tower became part of the newly created University of Technology Sydney in January 1988.

The Tower has been described very colourfully and identified numerous times as Sydney's ugliest building, notably in The Sydney Morning Herald, and by architect Frank Gehry.^[4][5][6] Journalist and author Mike Carlton described it as "a menacing concrete monolith in an architectural genre that the old East German Stasi brought to perfection".^[7]

The Tower's visibility in the central business district skyline has also been described positively, as marking Sydney as a University town.^[5]
