LEGO Brickstructures was a subtheme of Architecture that was released in 2008 and contained two of the very first sets created by Adam Reed Tucker, the Sears Tower and the John Hancock Center. Because Adam Reed Tucker was a Chicago architect the first models reflected his hometown inspiration. Both these original structures were re-released and slightly re-imaged in the Landmark Series subtheme.
The Architecture theme which was introduced in 2008 contains sets designed by Chicago architect Adam Reed Tucker based on real structures. Adam Reed Tucker's sets focus on incredible man-made sights and structures based upon the real world and comprised of microscale models. Unlike most LEGO, Architecture sets are typically not meant for playing but rather designed for display. The debut sets, released in 2008, were of two Chicagoan classics: Willis Tower, and John Hancock Center then New York City's Empire State Building, followed by Seattle’s Space Needle.
