Every LEGO Modular Buildings Collection Set Ever Released

Live data on every LEGO Modular Buildings Collection set: retail, current market value, ROI, and retirement status.

The LEGO Modular Buildings Collection is the longest-running and arguably the most coveted line in LEGO's Icons (formerly Creator Expert) portfolio. Launched in 2007 with the original Cafe Corner (10182) and continuing roughly one new release per year, the series is built around shared design principles: a consistent 32-stud square footprint, removable upper floors, modular street-side connections, and an extraordinary level of architectural detail aimed squarely at adult collectors.

What makes the modular line distinctive isn't only the build experience — it's the resale behavior. Limited production windows, large piece counts, and a fervent secondary-market following have made several modulars among the best-performing LEGO sets ever sold, with retired entries regularly trading at multiples of their original retail prices. That track record has turned the modular series into a default starting point for LEGO investors weighing what to buy, hold, or sell.
