LEGO marks 20 years of Modular Buildings in 2027 with giant fan-built versions

# What's happening

# The scope and scale

Each participating community will design, engineer, and build its own oversized Modular Building. Most groups are working with about 500,000 LEGO elements per build. Two of the largest community builds will use approximately 750,000 elements each. Combined, the 22 projects represent about 11.5 million LEGO elements.

This is a large distributed effort: each community follows shared standards so the individual buildings can align visually and physically when displayed together, but individual groups retain significant creative freedom over their building's appearance and interior features.

# Where and when you'll see them

The giant modulars will be exhibited at major LEGO fan events and public exhibitions during 2027 and into 2028. When venue space and scheduling allow, multiple oversized modular buildings will be brought together to create larger streetscapes and displays that show the overall scale of the collaboration.

# Who's taking part

MUGs (an Australian group) has already teased their submission: a large-scale Palace Cinema. The project list encourages fans to follow each community's social channels to monitor progress.

# How the builds will be coordinated

Communities will adhere to shared standards for dimensions, connection points, and exterior design language so independently built sections can be joined into coherent displays. Within those constraints, each group determines the creative and engineering details for its building, including interior layouts or bespoke exterior treatments.

# Context and precedent

LEGO previously marked the Modular line's 10th anniversary with a commemorative set (Assembly Square). This announcement is a different approach: instead of a single LEGO-released set, it's a distributed, community-driven celebration that amplifies the scale and public visibility of Modular Buildings by turning several fan-built models into exhibition pieces.

# What to watch for

Follow the listed communities for photo updates, build progress, and exhibition schedules. Expect staggered reveals through 2027 and appearances at fan conventions and public exhibitions into 2028. Look for announcements about when multiple oversized modulars will be displayed together, which will show how the shared standards allow separate builds to link into larger streetscapes.

# Practical takeaway

If you want to see these mega-scale Modular Buildings in person, track the social channels and websites of the participating Recognized LEGO Fan Communities for local exhibition dates. If you follow specific community builds (for example, the teased Palace Cinema), you can track milestone updates and behind-the-scenes engineering posts as they prepare millions of elements for display.
