One South Church, Office building in Tucson, US
One South Church is a 23-story office tower at 1 South Church Avenue in downtown Tucson, designed by Fentress Bradburn Associates of Denver as one of a pair of twin towers; the second was never built. Its shaft is clad entirely in dark brownish-bronze glass panels set in a dense grid of vertical and horizontal mullions, with setbacks and a central vertical recess near the stepped top. The Leo Kent Hotel opened in the bottom nine floors in 2023.
Construction began in 1985 with M. M. Sundt Construction Company of Tucson as general contractor, and the building opened in 1986 as the United Bank Tower. Designed by Fentress Bradbrum Associates of Denver as one of two planned twin towers, it was the only one built. It later became the Citibank Tower, Norwest Tower and UniSource Energy Tower before taking its address name in 2011.
The building serves as a major business hub in the city center, home to law offices, insurance companies, and professional firms. It shapes the look of downtown and is a familiar workplace for many in the local business community.
The building has multiple elevators and underground parking available, making it easy to access the structure. Keep in mind this is an active business building, so common areas are easiest to navigate during regular business hours.
Locals call it "The One with the Blue Roof," a nickname the bronze-toned glass of the photo does not suggest. The building was designed as one of two twin towers for a downtown complex; the second tower was never built. The Leo Kent Hotel opened in its bottom nine floors in 2023.
