The wall is perforated so doors and hallways go through. A 'spine wall' in the tower’s midsection links two outer cores, helping the two towers act as one unit. Six tanks, holding more than 400,000 US gallons (1,500,000 L 330,000 imp gal) of water, counteract the movement of the wind. The building contains uninhabited 'blow-through floors' to reduce wind-induced sway. This 2-ft-thick spine transfers wind loads from the middle tower to the cores of the 51-story tower to the east and the 101-story tower to the west. For gravity loads, columns that continue to foundations support a 123-ft-long spine wall. The two outer cores are tied together via a 508-ft-tall reinforced concrete spine, from floors 15 to 51 above the upper street grade. The tower uses coupled dual-core shear-wall assembly that connects the three buildings for wind resistance. This was chosen over using columns set on a diagonal, which would have sacrificed interior space. Each column projects about 5 inches outward or inward from the one below it. Unlike most buildings, the building's perimeter columns step inward and outward instead of going directly upwards. The structural engineering of the tower was managed by Magnusson Klemencic Associates. Philadelphia-based OLIN will design the project's green spaces, including the rooftop gardens.

The tower has a notably smaller footprint than other supertalls in Chicago with a building height-to-core aspect ratio of 40-to-1.Ĭondominium interiors will be designed by hospitality design firm Hirsch Bedner Associates, while the hotel interior will be designed by San Francisco firm Gensler. The design was described as 'stacks of tapering, truncated pyramids that alternate between right-side-up and upside-down' by the Chicago Tribune. The towers have 6 different shades of glass. The three towers feature a curvilinear design, and are made up of alternating frustums. Upon completion, Vista Tower designers are targeting a Silver Leadership in Energy and Environmental Design (LEED) certification. Mechanical space occupies the remaining floors. Totalling a height of 101 stories, the east, middle, and west towers are 47, 71, and 93 stories tall, respectively. The design has three interconnected volumes with differing heights. Chicago based bKL Architecture is the project's architect of record. The building's chief architect is Jeanne Gang, head of Studio Gang Architects. Regis Chicago at 363 East Wacker Drive from Lake Point Tower, 2022 Regis contains 393 condominium residences, and 191 hotel rooms, including 33 suites. In keeping with the general plan, The St. The project was initially planned to house Wanda's Vista luxury hotel brand, its first in North America, and include condominium residences. According to Studio Gang Architects, the tower 'presents itself as three interconnected volumes of differing heights, moving rhythmically in and out of plane' as a result of the curvilinear design. The composition has been likened to sculptor Constantin Brâncuși's Endless Column. The stems are formed from alternating truncated pyramidal shapes called ' frustums', giving each tower an undulating appearance, further accentuated by differing shades of glass in alternating pattern. The structure consists of three interconnected towers, called 'stems' with differing heights in a step-like arrangement. Regis Hotels & Resorts, which opened the hotel portion on May 19, 2023. Magellan bought the project entirely in 2020, and then partnered with St. Initially a joint project between Magellan Development Group and Chinese based Wanda Group, the skyscraper cost nearly $1 billion to construct.

Regis complements the design of the nearby Aqua skyscraper, also designed by Gang, as the two tallest structures in the world designed by a woman. It forms a part of the Lakeshore East development and overlooks the Chicago River near Lake Michigan.ĭesigned by architect Jeanne Gang and her architectural firm, Studio Gang Architects, the St. It is the tallest structure in the world designed by a woman. Upon completion it became the city's third-tallest building at 1,198 ft (365 m), surpassing the Aon Center. Construction started in August 2016, and was completed in 2020. Regis Chicago, formerly Wanda Vista Tower, is a 101-story, 1,198 ft (365 m) supertall skyscraper in Chicago, Illinois.
