Hennepin County Government Center, Minneapolis, MN

Amid much controversy, the stylish Hennepin County Government Center opened in 1973. Many citizens and public officials alike felt it was too extravagant for a Minneapolis public building. Architect John Warneke was criticized for his use of certain materials and overall design. Many felt onyx boardroom panels and fragile Swiss tiles on the plazas were too lavish and not very cost effective. The large atrium was deemed poorly planned, as heating and cooling inefficiencies were feared. The twin towers have, however, survived the test of time and the critics grew to love the way the 24-story atrium was constructed to neatly frame the clock tower of the historic Minneapolis City Hall. The exterior purple gray granite, quarried in Ortonville, Minnesota, is the same as that used for City Hall. This, too, was hailed as a stroke of genius on the part of Mr. Warneke. The two plazas, one with a spectacular waterfall and the other with a grassy terrace, are well-liked spots for business types and downtown visitors to enjoy a stroll or an outdoor lunch.
