About this creation
This is my twenty-eighth skyscraper model. Chase Tower is located at 10 South Dearborn Street in Chicago. The building opened in 1969 as First National Plaza and served as the headquarters for First Chicago Corporation. When it became the headquarters for Bank One Corporation in 1998, it was renamed Bank One Tower. The current name has been in place since 2005 when Bank One merged with Chase.

This is my sixteenth Chicago skyscraper model and is among one of the most difficult designs I have tackled. Due to the building's unique concave sloping fašade, I had to physically mock-up more than two-thirds of the building with spare parts in order to integrate the curved shape while also testing structural integrity overall. The model took more than five months to design, about three days to build, and an overall six months to complete. Model completed January 14, 2014.

At 850 ft and 60 floors, Chase Tower is the tallest building within the Chicago Loop. Including all of Chicago, however, it is only eleventh tallest in the city.






The building occupies an entire city block, bound by Clark, Dearborn, Madison and Monroe Streets. Interestingly, to make way for the construction of this building, the entire pre-existing block was razed, including the Morrison Hotel, Chicago, which at 526 ft, was the tallest building to have ever been razed at the time. It's unique dark red fašade and intriguing history (it was the first building outside New York City over forty floors) make it a perfect candidate for one of my upcoming models. Stay tuned!

The main construction method I used for this model was primarily integrated along the exterior columns which are made up of 1x2 tiles and 1x2 plate with two clips which grasp a flex tube on the inside. Attached to the flex tubes between the clips at various intervals are 1x2 hinges with female attachments. Each of these hinges holds only 5-10 floors before each is topped by a jumper plate so as to form a "loose" connection to the series of floors above, thereby allowing each hinge's sets of floors to form a smooth inward curve. You can also see the link above for a more visual explanation of the aforementioned.

The building is also known for its large outdoor gathering space, Exelon Plaza, which provides a large public area at the geographic center of the Chicago Loop. The plaza's namesake, Exelon, is also headquarted at Chase Tower. The plaza provides access to the lower lobby of Chase Tower and features an on-site McDonald's in the southwest corner, a jet fountain and Marc Chagall's Four Seasons ceramic wall mural.

Looking down. The rooftop level features large AC units, to which a large Chase logo is mounted on either side. Representing these in the model are two white grill tiles and a 1x1 round blue tile.

Quoting david drake Love the nonlinear design you tackled. We parked right beside this tower in December when we visited the Christkindl Market at Daley Plaza. This bldg amazed me, but it was 32 degrees at the time, the coldest it had been all winter, so I only stopped to take a single picture of the base of the tower. Great build, and I'll definitely have to take a look at the external link to better understand how you got the smooth curved lines of this Lego masterpiece. Great work!
Thanks David. And you must have visited Chicago on a good day if it was that high of a temperature!

Quoting Milo Krimstein As usual, fantastic! I would love to see you organize a 1:650 scale Chicago (using just the buildings that you have), I think you have enough to form a solid skyline!
Haha, well maybe not enough to form a solid skyline just yet. Maybe in ten years :)
