1. LEGO Natural History Museum (10326)
The Natural History Museum marks a historic moment for the Modular Buildings Collectionâit’s the first museum ever added to the line. This massive 4,014-piece set captures the grandeur of a classic natural history museum with stunning Beaux-Arts architecture, complete with ornate columns, a domed entrance, and intricate stonework details.
Why it’s great: The interior is where this set truly shines. You’ll find a dinosaur skeleton on display (a T-rex fossil that’s become instantly iconic), gem and mineral exhibits, a gift shop, and even a rotating globe. The building features three levels with removable sections for easy access and display. At $299.99, the price-per-piece ratio is excellent for a premium set of this size.
Best for: Collectors who want a statement piece, dinosaur enthusiasts, or anyone building a comprehensive modular city. The museum adds a completely new building type to your street and works wonderfully as a centerpiece.
Minor downside: The double-wide footprint means it takes up more shelf space than standard modulars. Budget-conscious collectors may need to save up for this premium set.
If you’re looking for the most impressive modular currently available, the Natural History Museum delivers unmatched detail and display presence.
2. LEGO Boutique Hotel (10297)
The Boutique Hotel brings art deco glamour to the Modular Buildings Collection. Its unique wedge shape is designed to sit on a corner, connecting two streets at an angle. The exterior features beautiful geometric patterns, gold accents, and a striking teal color scheme that stands out from other modulars.
Why it’s great: The hotel packs three stories of detailed interiors: a lobby with reception desk, guest rooms with period-accurate furniture, and a rooftop terrace with a swimming pool. The corner design adds architectural interest and helps create more dynamic street layouts. At 3,066 pieces for around $199, it offers solid value for money.
Best for: Builders who want something different from standard rectangular modulars. The art deco style pairs beautifully with other early-20th-century-themed sets and makes an excellent corner anchor for your modular display.
Minor downside: The wedge shape requires thoughtful placementâit needs to go on a corner, which limits flexibility. Some collectors find the teal color polarizing (though most love it).
For combining unique architecture with excellent playability, the Boutique Hotel is a fantastic choice.
3. LEGO Police Station (10278)
The Police Station brings 1940s charm to your modular street with its striking blue brick facade and classic American architecture. This 2,923-piece set actually includes two buildings: a three-story police station complete with holding cells and detective offices, plus an adjacent donut shop that adds both humor and authenticity to the design.
Why it’s great: The attention to storytelling detail sets this modular apart. Easter eggs aboundâfrom newspaper headlines about a jewelry heist to a donut-loving cop stereotype played for laughs. The interiors are packed with character: a reception desk, chief’s office with ceiling fan, interrogation room, and jail cells with a would-be escapee. The donut shop has a full kitchen and seating area. Five minifigures bring the scene to life.
Best for: Fans of classic Americana and those who appreciate sets with narrative elements. The Police Station works brilliantly alongside the Bookshop and other vintage-styled modulars, creating a cohesive mid-century street scene.
Minor downside: Released in 2021, this set is now retired from LEGO stores and only available through resellers. Prices may be above original retail, so act fast if you find it at a good price.
For a modular that tells a story while looking stunning on display, the Police Station delivers charm in spades.
4. LEGO Bookshop (10270)
The Bookshop has become a beloved classic in the Modular Buildings Collection. This 2,504-piece set actually gives you two buildings: a charming three-story bookshop with a beautiful bay window facade, and an adjacent townhouse with a distinctive purple-gray color scheme.
Why it’s great: The bookshop interior is wonderfully detailed with shelves full of books, a reading nook, and cozy living quarters upstairs. The townhouse features a birdbath in the back garden and furnished rooms throughout. The two-building format means you’re essentially getting two structures for the price of one, making it exceptional value.
Best for: First-time modular builders or anyone who appreciates classic architectural charm. The Bookshop has that quintessential “LEGO street” aesthetic and pairs wonderfully with almost any other modular.
Minor downside: The Bookshop retired from LEGO stores, so it’s only available through secondary markets (like Amazon) where prices may vary. Act quickly if you spot it at a good price.
For timeless appeal and excellent value, the Bookshop remains one of the most recommended entry points to modular building.
