LEGO is taking architectural building sets to a whole new level with the launch of the Architecture Sagrada Família. Now available for preorder at $800, the massive 12,060-piece model is officially the largest LEGO building set ever released.
Inspired by Barcelona’s iconic basilica, the new set is designed for adult builders and architecture enthusiasts looking for a long-term project. It features detailed facades, soaring towers, and even stained-glass-inspired effects.
LEGO’s Biggest Building Set Ever

At 12,060 pieces, the Sagrada Família surpasses every previous LEGO building set, making it the largest architectural model the company has ever produced. Once completed, it becomes a display piece that measures more than 24 inches tall and nearly 19 inches wide.
The model follows the real-world construction journey of the famous basilica. You’ll begin with the Apse and Crypt before moving on to the Nativity Façade, the only section completed during Gaudí’s lifetime.
From there, the build expands through the naves, sacristies, towers, and the Glory Façade. It’s a rewarding challenge that lets you build the cathedral’s distinctive architectural details, including the stained-glass effect incorporated into the windows.
Designed for Serious Builders

LEGO describes the Sagrada Família as a build intended for adults ages 18 and older. The realistic construction sequence and high piece count make it one of the most ambitious LEGO Architecture sets ever created.
You can also use the Builder app for enhanced instructions, including 3D viewing tools that allow you to zoom, rotate, and track progress throughout the project.
Whether you’re a longtime collector, a fan of European architecture, or someone who enjoys immersive creative projects, you’re bound to appreciate the detail and craftsmanship of this build.
An $800 Centerpiece for LEGO and Architecture Fans

With a preorder price of $800, the Architecture Sagrada Família sits firmly in premium collector territory. But its record-breaking size, detailed design, and connection to one of the world’s most recognizable landmarks make it one of LEGO’s most ambitious releases to date.
For fans of architecture, travel, and large-scale builds, the new Sagrada Família could become one of the most impressive display pieces the company has ever produced.
