Designed by Naess and Murphy, One Pru stood as a beacon of rebirth and a new age of prosperity for Chicago when it was completed in 1955. Heralded by Mayor Daley as “41 stories of faith in the future of Chicago,” the limestone and rigid aluminum building ended a two-decade hiatus of skyscraper construction following the The Great Depression and economic strain of World War II.

The city’s tallest building at the time, One Pru boasted the world’s fastest elevators and quickly became Chicago’s most prestigious office address, serving as headquarters to some of the world’s most powerful companies, including pioneering ad agency Leo Burnett.

Each building, a landmark of its own. Together, a 2.3 million-square-foot powerhouse of influence and inspiration.


Building Upon A Great Chicago Story

True to its triumphant story, One Two Pru has now been reimagined for a new wave of Chicago workforce and culture. Alongside the re-emergence of the East Loop, the prominent two-skyscraper development has been thoughtfully revitalized by Sterling Bay, a developer renowned for bringing inspired new beginnings to storied Chicago properties.

The result of these revitalization efforts is a high-end office and amenity experience that caters to the needs of the modern workforce.


Most impressively, an eleventh floor roof deck overlooking Millennium Park offers Chicago’s most legendary gathering space, while a tenant lounge — designed and run by Convene — offers craft cuisine and a stylish contemporary backdrop for coworking, networking or taking a mindful minute. A storied Chicago landmark has found its new chapter as a platform for thought-leading companies of tomorrow.
