How to Choose Your First LEGO Modular Street Building

The short answer first: LEGO modular street buildings are among the most replayable series you can buy. For a first purchase, start with something in the roughly 1,000-yuan class, such as a corner grocery store or the Jazz Club, and only step up to a three-storey flagship if the budget comfortably allows it. Build in the order baseplate, ground floor, upper floors, roof, interior — and once you have four buildings, you can line them up into a street that actually tells a story.

1. Set Your Budget and Display Space First

Every modular building sits on a 32x32 baseplate, so a single model occupies about 25.6 cm square, with finished heights typically between 28 and 35 cm. Measure your display spot before you order anything: four buildings side by side need a surface roughly 1.2 m wide and 35 cm deep. On price, entry-level models mostly land between 800 and 1,500 yuan, while flagships such as 10297 Boutique Hotel — more than 3,000 pieces — run past 2,000 yuan. Spend within your means.

2. Choosing the First Building: Three Entry Options

• Around 1,000 yuan, single building: 10312 Jazz Club (2,899 pieces) has a clean, regular structure and a rich interior, and it is the best-regarded entry model of recent years. The corner grocery store (around 2,000 pieces) is a classic, easy-on-the-eye choice for anyone who likes American-style street corners.
• Mid-sized buildings: sets like Assembly Square and the Bookshop, which pack plenty of minifigure interaction detail, offer strong value and suit newcomers who want to sample the modular atmosphere first.
• Flagship towers: three-storey-plus builds such as the Boutique Hotel and Town Hall usually take 8-12 hours to assemble. Save these for your second purchase so your first one does not put you off.

3. Four Rules for Building Floor by Floor

1. Level the baseplate first: assemble the 32x32 baseplate and foundation, and confirm which way the street faces before going further, so you do not have to redo it later.
2. The ground floor sets the style: the soul of a modular building is its street-facing facade. Finish the shop windows, signage and doorway first, then let the upper floors continue that same style.
3. Upper floors detach: most modular buildings use a modular structure, with the second and third floors built separately and stacked on top, so you can lift them off later to enjoy the interior.
4. The roof comes last: slope pieces sit at awkward angles, so follow the instructions step by step and do not skip ahead.

4. Going From One Building to Four: Joining the Street

When you buy your second building, prioritise one with an identical baseplate footprint and a colour scheme that contrasts with the first. To join the street, clip neighbouring buildings together with their baseplates, leave a sidewalk width of about 4 studs between them, then add streetlights, benches and street trees. The street feel appears instantly. A recommended combination: grocery store + bookstore + Jazz Club + Boutique Hotel. The four facades vary nicely in rhythm, the finished street is about 1 m long, and it looks striking on display.

5. The Loose-Part Option on a Tight Budget

New sealed sets carry a high premium. To save money, search for street-scene MOC instructions on brickplan.cn and source the parts yourself from the parts list. For a mid-sized street building, loose parts usually cost only 50%-60% of the official set, and you can swap colours freely to build a street that is uniquely yours. The downside is that sourcing parts takes time, so this route suits builders who are not in a hurry to finish in one sitting.

FAQ

Q: Which modular building should I buy first?

A: 10312 Jazz Club is the top pick — 2,899 pieces, a clean structure, a detailed interior and moderate difficulty. The finished model photographs beautifully on a shelf and is widely agreed to be the most beginner-friendly modular building of recent years.

Q: Can modular buildings be mixed with other LEGO series?

A: Yes. They all use 32x32 baseplates and are compatible with LEGO City and Collectible Minifigures. As long as the baseplate size matches, you can combine them freely, and many builders pair modular buildings with minifigures to create their own small town.

Q: Is a retired modular building worth paying a high price for?

A: Retired modular buildings typically carry a 2-3x premium, and beginners are advised not to chase them. A better-value approach is to find MOC instructions in the same style on brickplan.cn and recreate the building from loose parts — lower cost, and you can recolour it to taste.

Q: Roughly how much does a full street cost?

A: Four new sealed sets come to about 5,000-8,000 yuan. With the brickplan loose-part route, a mid-sized building runs about 600-1,000 yuan each, so four buildings stay under 3,500 yuan — saving roughly 40% of the budget.
