21000-1 - Sears Tower

Commemorate a foundational piece of architectural history with the **LEGO Architecture 21000 Sears Tower** (later renamed Willis Tower). Released in 2008 as one of the very first sets in the landmark series, this retired collector’s item captures the iconic stepped-tube design of Chicago's most famous skyscraper. Designed by original theme visionary Adam Reed Tucker, its minimalist black tile aesthetic makes it a sleek, historic display piece perfect for executive desks, architectural studios, or nostalgic high-value LEGO portfolios.
