About Modular Buildings

How the system works

Every building follows the same rules. It sits on one or more 32 × 32 stud baseplates, the floors lift off so you can reach the furnished interiors, and Technic pins join neighbouring buildings side by side. Pavements line up, so a café, a bank and a police station form a continuous street regardless of the year they were released. The series began in 2007 with Café Corner and has added a new building in most years since, often with inventive facade techniques that builders study and borrow for their own models.

The heavyweights

Natural History Museum (10326-1) from 2023 tops the list at 4,015 pieces, only 13 ahead of Assembly Square (10255-1), the 2017 release with 4,002. Shopping Street (11371-1, 2026) has 3,457 pieces and Tudor Corner (10350-1, 2025) 3,266. Boutique Hotel (10297-1) comes to 3,068, Police Station (10278-1) to 2,923 and Jazz Club (10312-1) to 2,900. Town Hall (10224-1) from 2012 rounds off the top eight with 2,772 pieces.

Building a street of your own

Retired modulars are sought after, so many fans rebuild older ones from loose bricks instead. Each set page on Bricoria has the full parts list, which makes it easier to plan what you still need. The theme also includes one sub-theme, Mini, a single 2012 set that shrinks early buildings of the range down to a much smaller scale for display on a shelf.

Who they are for

The building techniques and piece counts put these sets firmly in adult territory, though they work in any minifigure layout, including a City or train setup. Some collectors buy every release and arrange them in order of year; others pick buildings by colour and style and treat the series as a kit of parts for their own town. Either way, the shared grid means nothing ends up orphaned.
