LEGO Ideas Downton Abbey 21373 is the largest Ideas set yet at 4,711 pieces

LEGO Group unveiled LEGO Ideas Downton Abbey 21373 on September 10, turning Highclere Castle’s upstairs-and-downstairs world into a 4,711-piece model—the largest LEGO Ideas set by piece count at announcement. Beyond the facade, a removable upper floor reveals rooms on both levels and small period details throughout.

A 44 cm facade built from 4,711 pieces

Designed for adults 18+, the model stands over 30 cm high, 44 cm wide, and 16 cm deep. The US LEGO Shop lists it at $349.99 as a coming-soon product. LEGO Insiders early access begins October 1, followed by general availability on October 4, 2026.

Lift off the upper floor, then follow the house downstairs

The removable upper level contains the dining room, main hall, and library. Below them sit the kitchen, servants’ hall, and Mr Carson’s office. The period setting appears in candlelight placed beside early electricity, an early electric mixer, and a 1910s–1920s candlestick telephone. Even the servants’ hall table is arranged according to rank.

Thirteen Season 6 characters—and the fan designer’s signatures

The household is represented by 13 minifigures with double-sided faces and extra clothing elements designed for seated dining poses. Fan designer Sebastian Veselka, known as BRO3 on LEGO Ideas, created the original concept and reached 10,000 supporters in three months. His smaller Easter eggs include a LEGO room label on the servants’ bell board, SV initials on newspapers, and a heart-shaped tree base.
