400 North Lake Shore Drive

The Chicago Spire is an uncompleted, now-defunct skyscraper project in Chicago, Illinois. After several years of on-going financing challenges, including the recession that began in 2008, construction was halted.Anglo Irish Bank Corp., filing a $77 million foreclosure lawsuit against The Spire's Irish developer Garrett Kelleher, claims that loans made to Kelleher’s development company have been in default for a year. The bank was expected to take possession of the site where the Spire was to be built.

The building was designed by Spanish architect Santiago Calatrava and was being developed by St Patrick's Athletic owner Garrett Kelleher of Shelbourne Development Group, Inc. At 2,000 feet (610 m) and with 150 floors, it would be among the world's tallest buildings and freestanding structures, and the tallest building in the United States and the Western Hemisphere. Originally proposed by Christopher T. Carley of the Fordham Company in 2005, the project was supported by many Chicagoans and city officials.

After several months of development in 2005, Carley failed to acquire necessary financing and the project was taken over by Garrett Kelleher of the Shelbourne Development Group in 2006. Since that time, three revisions were made to the design and the renamed project gained city approval. Following the start of the late-2000s recession, and its impact on the primary lender for the project, construction was suspended at the site. Amid several unsuccessful attempts with labor union investment funds to bail out the project, Shelbourne Development continued its attempt to secure additional financing and restart construction and insisted that the project is not dead.

By the end of 2010 legal actions by Anglo Irish Bank caused the courts to hand control of the site to a receiver, leaving the project dead.


Fordham Spire

When originally proposed as the Fordham Spire in July 2005, the design had 115 stories. Chicago developer Christopher T. Carley of the Fordham Company was spearheading the project. The building was planned to include a hotel and condominiums and also featured a tall broadcast antenna mast. On March 16, 2006, the initial design of the building passed unanimously during that day's meeting of the Chicago Plan Commission and on March 23, 2006, the same happened at the city's Zoning Committee meeting. On March 29, 2006, the Chicago city council also approved that design. As part of the approval process, the council passed a measure that raised the height limit on structures at the site to accommodate the 2,000-foot (610 m) tower.

There was widespread support for the original design of the building among both the residents of the immediate neighborhood and the city of Chicago as a whole, partly because the building would block less sunlight and obscure less of the skyline than the lower buildings for which the land was originally zoned. Chicago Mayor Daley said he approved of the design, stating that it was environmentally friendly. Burton F. Natarus, who was the 42nd-ward alderman when the building was announced, said: "This is a very unique opportunity for the city of Chicago. This building belongs to Chicago and should be in Chicago."

Some opposition from neighborhood residents originated from concerns with increased congestion. Donald Trump immediately voiced opposition to the building, stating that the tall structure would be a target for terrorists and did not even seem to be a viable project. The comment was ironic considering he was developing a project, the Trump International Hotel and Tower, that is also a supertall skyscraper, which completed construction in January 2009 just a few blocks west of the Chicago Spire site. If the Chicago Spire had been built as planned, it would have replaced the Trump International Hotel and Tower as the tallest residential structure in the United States, and the two towers would have been in direct competition in selling residential units.

Initial financial problems

After several months of development, Carley failed to obtain sufficient financing for the construction of the building.Irish developer Garrett Kelleher, executive chairman of Shelbourne Development Group, Inc., stepped in and acquired the land, which is located at 400 North Lake Shore Drive. It was announced that he would fund the development. With Kelleher taking over the project, the uncertainty of its development was thought to be diminished because Kelleher stated he was putting up 100% of the equity, something Carley had been unable to do. He also had financial backing to acquire the land, something Carley lacked. Kelleher stated he would consider using Carley's services on the development and that "Carley will be paid an unspecified sum for his involvement in the deal so far." Kelleher later renamed the project "Chicago Spire" after shortly going by "400 North Lake Shore Drive", as it was no longer a Fordham project.

New designs

In the final quarter of 2006, Shelbourne Development issued two separate press releases regarding the construction and design of the spire. A November 2006 press release stated that construction of the Chicago Spire would begin in June 2007. In early December 2006, Shelbourne Development issued another press release stating that the design of the building had been revised. This included the removal of the hotel and the antenna mast, making the building consist solely of condominium units. The design change altered the twist to be consolidated towards the base of the building, which was also wider than the original plan. Additionally, the spire no longer tapered at the top, resulting in an increase in floor space and overall floor count. The revision also removed the separate parking structure from the original plan, instead incorporating underground parking into the spire itself. This first major redesign of the Chicago Spire was criticized by architectural critics and city officials.

In late December 2006, the Chicago Tribune reported that the developer was soliciting opinions on a further revision from community leaders. Several weeks following that report the Chicago Tribune held an exclusive interview with architect Santiago Calatrava and lead developer Garrett Kelleher. During the interview, Calatrava drew out design ideas restoring the rotating design of the building and showcasing his vision for the Chicago Spire's lobby. On March 26, 2007, further revisions were shown during a public presentation by Shelbourne Development showcasing the most recent design.


Following the March 26, 2007 public presentation by Shelbourne Development, residents showed favorable reaction to the newest design of the Chicago Spire. The Chicago Plan Commission approved the final plans of the Chicago Spire on April 19, 2007. Chicago's zoning committee also approved the tower on April 26 and, on May 9, 2007, the Chicago City Council approved the final design of the Chicago Spire.


By June 2008, Shelbourne had sold more than 350 of the 1,193 units—more than half of those to foreign investors in markets where certain United States Securities and Exchange Commission regulations do not apply. Shelbourne announced on September 30, 2008 that the building's penthouse was sold to Beanie Babies manufacturer Ty Warner. Kelleher offered to rent out units at a guaranteed 7.5% return to spur sales. The approach is common outside the United States where the tower was marketed more heavily and was meant to spur sales of the smallest units, which are most the likely to be purchased as rental property investments by foreigners.

Financial crisis and suspension of construction

By October 2008, the late-2000s recession was beginning to have an impact on the project. Construction was suspended and the tower's architect, Santiago Calatrava, placed an $11.34 million (USD) lien on the construction site, stating that Kelleher had not yet paid him for his work. Within a few months Anglo Irish Bank, the primary lender for the project, was on the brink of financial collapse. The bank's stocks had lost nearly all of their value and Anglo Irish Bank was facing nationalization. Due to the bank's dire financial situation, Shelbourne Development was forced to suspend construction, and would eventually have to pay back the $69.5 million (USD) it had already borrowed.

Additional litigation and liens threatened the project by autumn 2009. The owner of the NBC Tower in Chicago sued to evict Shelbourne Development from their sales office, where extensive modeling of Chicago Spire units had been installed. The lawsuit alleged that Shelbourne was behind $316,000 (USD) in lease payments. In addition to this and other liens listed on the property,Bank of America filed a lawsuit against Shelbourne Development for $4.92 million (USD). The lawsuit was an attempt to collect that sum on two unpaid loans used for initial construction at the Chicago Spire site.

After these setbacks, the AFL-CIO and Kelleher announced in late 2009 that they were discussing the potential for a $170 million (USD) land loan that would retire Kelleher's loan from Anglo Irish Bank, pay off the outstanding liens, and restart work in exchange for making the construction a completely union job. Due to the lack of construction and the sluggish economy, Chicago unions were desperate to find work for their employees as they faced near 30% unemployment. Construction of the Chicago Spire would have provided approximately 900 full time jobs to union members for four years if construction had resumed. In addition to the $194 million (USD) that Kelleher has invested personally in the project already, backup financing of an unspecified amount and from an unknown source in the form of mezzanine capital and bridge loans has been guaranteed and would have kicked in automatically if the $170 million (USD) AFL-CIO loan had been secured.

But within weeks of the official announcement that Kelleher was searching for union bailouts, four major labor union investment funds declined to offer Shelbourne Development any loans. Kelleher continued to search for financing.

Shelbourne Development faced eviction from its offices on the 50th floor of 111 South Wacker Drive on which Shelbourne owed $27,600 in unpaid rent. Earlier in the year, the spire's Chicago sales office had been ejected from the nearby NBC Tower.


In December 2010 a receiver was appointed to manage the property during foreclosure proceedings by Anglo Irish Bank. In addition, two Chicago firms have purchased the real estate taxes on the property.

Due to the major setbacks mentioned above, the project was canceled in 2010.


The skyscraper was being constructed along Chicago's lakefront west of Navy Pier, located northeast of Chicago's Loop, in the Streeterville neighborhood of the Near North Side community area. The construction site is at the junction of Lake Michigan and the Chicago River, and is bordered by the Ogden Slip of the Chicago River to the north, North Lake Shore Drive to the east, the Chicago River to the south, and existing residential property to the west. The site was originally zoned for two 35- to 50-story buildings. Originally, it was to be sold by a joint venture of LR Development Company of Chicago and JER Partners of Virginia for $64 million to Christopher Carley of the Fordham Company. After numerous short-term extensions, and later Carley's failure to obtain financing, Kelleher of Shelbourne Development purchased the land instead and pledged to finance the rest of the project.

DuSable Park

When the project was first announced, the Fordham Company pledged almost $500,000 to assist in the development of the city's proposed DuSable Park, which would adjoin the property of the Chicago Spire. DuSable Park would cover 3.24 acres (1.31 ha) and a $11.4 million budget was planned for its renovation. On March 26, 2007, Shelbourne pledged to pay $6 million toward the development of the park, making up the deficit left over from the city's own initial pledge of $6 million and far exceeding the Fordham Co's initial offer. In May 2007 Shelbourne's pledge jumped to $9.6 million.

Soil tests performed in December 2000 on the soil of the proposed park showed contamination of radioactive thorium. Thorium was used by the Lindsay Light Company, which operated a location nearby. After the closing of the location in the 1930s, contaminated soil was dumped on the location of the proposed park. In March 2003, the Chicago Park District stated that the thorium clean-up on that land was incomplete. Hazards of contamination can be avoided by laying a minimum of 6 inches (15 cm) of concrete over any affected soil, an approach that would be more feasible for the site of the Chicago Spire than for the adjacent park.



As with many of his designs, Calatrava was inspired by themes and designs in nature for the tall, twisting skyscraper. He likened the structure to an imaginary smoke spiral coming from a campfire near the Chicago River lit by Native Americans indigenous to the area, and also related the building's newly designed pinnacle to the "graceful" and "rotating forms" of a snail shell.

Standing at 2,000 feet (610 m), the Chicago Spire would have further transformed the always-changing Chicago skyline. Plans for the tower included 1,193 condominiums with each of the building's 150 stories rotated 2.4 degrees from the one below it for a total 360 degree rotation. In February 2008, prices for the condominiums were announced as ranging from $750,000 to $40 million USD. For supplemental structural support, each floor would have been surrounded by cantilevered corners and four concave sides. Similar to the Willis Tower (formerly Sears Tower) and John Hancock Center observation decks, the Chicago Spire design included a community room on the top floor offering residents a view of four U.S. states. The design for the soaring four story lobby of the skyscraper included translucent glass walls framed by arching, steel-reinforced concrete vaults. The building has been described as a giant "drill bit" by the public and others in the media have likened it to a "tall twisting tree" and a "blade of grass".

The curved design, similar to that of Calatrava's Turning Torso in Malmö, Sweden, may provide two major benefits to the structure of the building. First, curved designs have a tendency of adding to the strength of a structure. A similar principle has been applied in the past with curved stadium roofs. In addition to structural support, the curved face of the exterior will minimize wind forces. In rectangular buildings, a fluid wind flow puts pressure on the windward face of the building; while air moves around it, a suction is applied to the leeward face. This often causes a sway in tall buildings which can be counteracted, at least partially, by stiffening the structure or by using a dynamic wind damper. Although the curved design of the Chicago Spire will not completely negate wind forces, a tapering concrete core and twelve shear walls emanating from it are installed to counteract these forces instead.

Additionally, the Chicago Spire was designed with world-class sustainable engineering practices to meet Leadership in Energy and Environmental Design Gold recognition. Sustainable features included recycled rainwater, river water used for cooling, ornithologically-sensitive glass to protect migratory birds, intelligent building and management systems, waste storage and recycling management, and monitored outdoor air delivery.


Following the city approval, it was announced that construction of the Chicago Spire was to begin in summer 2007 with caisson work scheduled to begin as early as June 2007. DuSable Park was designated as a staging area for the construction of the tower. The sales center for the Chicago Spire opened on January 14, 2008.

On September 19, 2008, a spokeswoman for the developer announced that construction was continuing on the building, but that the pace of construction would be slowed until the financial markets recovered from the subprime mortgage crisis. Kelleher promised that he still had financial backing, although analysts questioned the ability of the project to survive the current economic decline. A contractor to build the building's superstructure had not yet been named. The October 1, 2008 edition of The Wall Street Journal said that the building foundation was complete and the above ground construction would not continue until the markets recover.

Underground phase

Crane parts and construction equipment arrived at the site on June 25, 2007. The following day Shelbourne Development officially announced the first construction contract. In preparation for construction, 34 concrete and steel caissons were drilled 120 feet (37 m) into bedrock underground; this was completed June 25, 2008. A cofferdam with a 104 feet (32 m) diameter and 78 feet (24 m) depth was installed to create a work environment and would have later acted as a foundation for the building's core. Utility upgrades were planned for the surrounding neighborhood.
