🛠️ Building Tips & Tricks

📏

Perfect Fit

Each modular is 32x32 studs. Standard IKEA shelves (KALLAX, Billy) work perfectly at 15.75" depth.

🔗

Connecting Buildings

Use the included plates and Technic pins to securely connect buildings. Remove rear walls for an open "dollhouse" view.

🎨

Customization

Swap minifigures, add custom signage, or modify color schemes. The modular design makes customization easy!

📦

Storage

Built modulars are heavy (5-10 lbs each). Reinforce shelves for multiple buildings. Keep instructions and boxes for resale value.

🧹

Maintenance

Dust with a soft brush or compressed air. Avoid water. Disassemble carefully if moving buildings.

❓ Frequently Asked Questions

Which modular building should I buy first?

Start with one LEGO still sells: Natural History Museum, Tudor Corner, Shopping Street. Retired sets usually cost more secondhand. Which modular to buy second covers pairing corners and mid-block buildings.

How often does LEGO release new modular buildings?

About one a year: our catalog lists 22 official modular buildings from 2007 to 2026. Some years bring two and some none.

Do modular buildings connect to other LEGO sets?

Yes! The 32x32 baseplate is compatible with all LEGO City, Friends, and Creator sets. You can integrate vehicles, minifigures, and street elements from any theme.

What's the best way to display modular buildings?

Most collectors use IKEA KALLAX or Billy bookcases (15.75" depth fits perfectly). Alternatively, custom floating shelves at 16" depth work well. Display 2-3 buildings per shelf for stability.

Are older modulars worth the investment?

Some have sold well above their launch price, but we have market values for only a few of them (listed under Value vs. Retail above, with the month each was recorded), so this page does not put a figure on the series. Sealed sets sell for more than opened ones, and past gains do not guarantee future ones.

Can I customize modular buildings?

Absolutely! Popular mods include: adding interior lighting, changing color schemes, creating custom signs, adding minifigure families, and building custom modulars (MOCs) to fill gaps in your city.

What's the most valuable modular building?

We do not have current market values for the earliest modulars, such as Café Corner (10182, 2007) and Green Grocer (10185, 2008), so this page cannot name the most valuable one. Check recent sold listings for a current price before buying or selling.

How do I know when a set is retiring?

Each set page shows LEGO's expected exit date when we have one, and a set due to leave within six months carries a Retiring soon badge. LEGO.com also labels sets that are retiring soon.
