The second season of IIDA and AIA Chicago's Designers + Architects Talk series continued March 10 with a conversation focused on three large-scale, transformative, structural and interior transformations and repositioning projects in Chicago: Willis Tower, Tribune Tower, and the Old Post Office.

The weeks following this event have been transformative in ways that have affected us personally, professionally, and collectively and have sent ripples through the industry. While we understand that projects across the globe may or may not be paused at this time, we hope this enlightening conversation and the innovative reimagining of iconic architectural spaces in Chicago inspires and encourages creativity.

Moderated by Zurich Esposito, Hon. AIA, executive vice president of AIA Chicago, the panel featured Todd Heiser, IIDA, principal, Gensler; Sheryl Schulze, principal, Gensler; Meg Prendergast, IIDA, principal, The Gettys Group; and Lee Golub, managing principal, Golub & Company.

Along with being famous for food, jazz, and world-class museums, Chicago is a city with an incredible architectural history, and the architects and designers leading the charge today play an important role in the reimagining of some of the city’s masterpieces. Projects like the rebirth of the city's tallest skyscraper, the transformation of a neo-Gothic landmark, and the largest example of adaptive reuse in the country.

Willis Tower

Originally designed by SOM and completed around 1974, at 110 stories, the Willis Tower is still the tallest building in Chicago and one of the three tallest in North America. “Once home to only one tenant, it is now home to 15,000 tenants, and thanks to Todd Heiser and team, it is being recreated and reopened by Gensler,” said Esposito.

Heiser, who is also co-managing director of Gensler's Chicago office, grew up just outside of the city. He said working on a project like Willis Tower—"or Sears Tower as so many of us still call it,”—is a humbling experience and one that, for Gensler, has been a labor of love for the last five years.

As the tower went through a series of additions in the 1980s, a massive, almost impenetrable boundary was created around the base. "Much of our work was opening up the tower and allowing you to access the ground plate," said Heiser. "We want to make it less of a fortress and create Chicago's next plaza. This work, along with the updated lobby experience, celebrates the businesses that call the tower home."

The public lobby repositioning features a food hall, meeting and events space, restaurants, entertainment, a rooftop park, and skylight supported by 75,000-pound beams that offer a view of the south side of the Tower, and still "the fastest elevators in North America."

This new space is called Catalog, in honor of the building's initial tenant, Sears, Roebuck & Co., and serves not only the building's tenants, but it's more than 1.7 million annual visitors.

"The new space opens up the building tremendously," said Heiser, "and helps to position the area as Chicago's next great neighborhood."

Heiser's work is part of a more than $500 million renovation, the most significant restorative transformation in the building's 46-year history. In late 2019, the tower earned the Leadership in Energy and Environmental Design's (LEED) Platinum designation.

Old Post Office

Designed by the same Chicago architects behind our other favorite buildings— the Wrigley Building and Merchandise Mart—Old Post Office was built in 1921 and, for quite a while, was the largest post office in the world. “By the mid-90s, however, it's use was replaced, and the building was left vacant and neglected. But as Sheryl (Schulze, principal, Gensler) will tell us, 'The wait was worth it,’” said Esposito.

An icon that needed life support. The awakening of a sleeping giant. "Or sleeping beauty as we affectionately call her," said Schulze, "and we are very grateful for our developer, 601W Cos., who is her prince."

Gensler, whose efforts were led by Schulze and principal Grant Uhlir came to the project officially with 601W Cos., in May of 2016, because of their in-depth knowledge of the building.

"We were involved with several developers over the years who were interested in the redevelopment of the building, and that ultimately led to us being the best fit for 601," she said.

Set to be completed in 2020, the $800 million-plus redevelopment, and currently the largest example of adaptive reuse in the country, has modernized the massive structure, without sacrificing its historic character.

"This building is very unique in nature," said Schulze. "It's comprised of three buildings, with 250,000 square foot sweeping floor plates, 18-foot ceilings, and varying floor heights that create several loft-like spaces."

The office floors also still contain the original spiral mail chutes and other items like vaults and scales that speak to the building's history.

"We've been able to reinvent this building into a class A office with game-changing, robust amenities that activate this building and truly make it a destination," Schulze said.

Building amenities include a bar with a bocce court, a gym that includes a boxing ring, a 450-seat auditorium, a 4.5-acre rooftop park, and a library, which Schulze added, "was an amenity in the original building as well for postal workers.”

Tribune Tower

"The product of a 1922 worldwide design competition to create the most beautiful building in the world may now become the world's most beautiful condominium building," said Esposito.

"There's no maybe about it," followed Prendergast, who leads The Gettys Group team overseeing phase one of the reimagined Tribune Tower. Solomon Cordwell Buenz is the architect of record on the project.

While the Tribune Tower’s exterior and lobby are landmarked, everything on the inside was gutted to make way for new, high-end spaces. "We've learned to love it, embrace it, and then help it move forward," said Prendergast, whose designs honor the heritage and beauty of the building.

CIM Group and Chicago-based Golub & Company acquired the 35-story, 740,000 square-foot structure in 2016, and is in the process of developing it into 162 luxury condominiums.

"Each unit has a unique floor plan given the variables of the building," said Golub. For example, the newspaper's old executive dining room will be a single-family dwelling.

The tower's amenities will include a spa, fitness center, indoor pool looking over the iconic Chicago Tribune sign, a co-working lounge, meeting rooms, entertainment areas, and an event space featuring a bar and prep kitchen. A terrace on the 25th floor of the crown is framed by the building's flying buttresses and offers 360-degree views of the city.

"It's the most amazing thing you've ever seen," said Golub. "If we could bring people to the brown, we'd sell out in one second."

"This is an iconic and dramatic piece of history," Prendergast said. "It's a once-in-a-lifetime opportunity."

An icon begets an icon.
