LEGO's biggest set ever is a 12,060-piece Sagrada Família — and it costs $800

LEGO has unveiled its largest set in company history: the Architecture Sagrada Família (21065), a 12,060-piece replica of Antoni Gaudí's unfinished Barcelona basilica. It beats the previous record holder — the World Map set at 11,695 pieces — by 365 pieces. At $799.99 in the US and £649.99 in the UK, it lands November 1, 2026, timed deliberately to the centenary of Gaudí's death on June 10, 1926.

The build

The finished model stands 62 cm (just over 24 inches) tall, with a footprint of 47 cm wide and 39 cm deep. LEGO designer Rok Žgalin Kobe structured the build to follow the actual construction sequence of the real basilica — starting from the Apse and Crypt, moving through the Nativity and Passion façades, the central naves, and finally the six towers and the Glory façade. Stained-glass windows are rendered using transparent colored elements that catch the light in the same way as the real building. There are no stickers; every detail is either built or printed.

The set is squarely aimed at adults 18+. There are no minifigures — this is a display piece, not a play set. LEGO's Builder app provides 3D step-by-step instructions with progress tracking. Expect to spend somewhere between 25 and 35 hours completing it, which works out to roughly 6.6 cents per piece — competitive with the Eiffel Tower (10001) and Colosseum (10276) sets.

Timing and availability

The announcement on June 4, 2026 coincides with the real Sagrada Família's own milestone: the completion of the Torre de Jesucristo, which will make it the tallest church in the world. LEGO is leaning hard into the cultural moment.

Pre-orders are live now at LEGO Official and in LEGO Stores. Wider retail availability — Amazon, authorized dealers — is expected mid-2027. If the Colosseum and Eiffel Tower sets are any guide, Brickset notes that premium Architecture releases tend to hold their value well after launch, so early ordering makes sense if you're committed.

At $800, this is unambiguously a collector's purchase — but for anyone who has followed either Gaudí's work or LEGO's adult line, it's the most ambitious set the company has ever put out.
