Who Is This Set For?
Display & Collection
At 501 pieces, the finished model is built for a shelf or desk. Popular among adult fans and collectors who prefer challenging builds over play value.

The estimated 2-4 hours build time makes this ideal for spreading across evenings or weekends. A satisfying project that rewards patience.
Gift for Adult LEGO Enthusiasts
One of the most-gifted categories for fans aged 10++. Works well for birthdays, holidays, or as a personal treat for Architecture enthusiasts.
Build Tips
A five-minute sort by color or piece type before starting saves time hunting for specific bricks mid-step.
Follow the numbered steps in sequence — structural elements early in the build support everything that comes after.
Once built, direct sunlight yellows ABS plastic over time. A display case or UV-filtered shelf glass keeps colors vibrant.
