Lego's New $800 Sagrada Familia Is Its Biggest Set Ever

The LEGO Icons Sagrada Familia (Set 10342) is a highly detailed, 10,001-piece construction model replicating Antoni Gaudí's unfinished basilica in Barcelona, Spain. Manufactured by The LEGO Group and released in March 2025, it is the company's largest-ever set by piece count for a three-dimensional model and retails for $799.99 / €799.99 / £699.99. Falling within the adult-focused LEGO Icons line, it is designed to provide an immersive, multi-day building challenge for advanced hobbyists. The set transforms the iconic landmark's Nativity Façade, Passion Façade, and soaring towers into a brick-built display piece, fulfilling a niche for collectors seeking monumental, art-meets-engineering experiences that double as sophisticated home décor.

Key Facts

How Big Is the LEGO Sagrada Familia Set?

The assembled model measures approximately 44 cm (17.3 in) tall, 38 cm (15 in) wide, and 38 cm deep, weighing over 8 kg (17.6 lbs). Its 10,001 pieces are spread across multiple modular sections for manageable construction, ultimately forming a footprint that rivals a large desktop printer. This scale makes it the most voluminous and heaviest LEGO architectural model to date.

"This 10,001-piece behemoth is not just a set; it's an architectural statement piece that pushes the boundaries of what's possible with plastic bricks."

With 10,001 pieces, the Sagrada Familia set ties the Eiffel Tower as the piece-count record holder for a three-dimensional LEGO model and is the heaviest Icons set yet at over 8 kg.

What Makes the LEGO Sagrada Familia Set Unique?

The set captures Gaudí's organic architecture through innovative brick-built curves, textured stonework, and multicolored translucent pieces that recreate the basilica's stained glass glow. It is the first LEGO model to feature all three of the Sagrada Familia's façades—Nativity, Passion, and Glory—at a consistent scale, with a partially removable roof to display the interior's branching columns.

"Every brick was chosen to evoke the weathered stone and vibrant stained glass of the real basilica," a LEGO spokesperson told Kotaku. "Builders will discover clever part usage that mirrors Gaudí's fusion of nature and structure."

It remains the only commercially available LEGO set that reconstructs all three iconic Sagrada Familia façades without sacrificing proportional accuracy.

Who Is This Set For?

This set is exclusively for adult LEGO enthusiasts with extensive building experience, a dedicated display area of at least 40 by 40 cm, and a $800 budget. It appeals particularly to architecture lovers who appreciate Gaudí's work and collectors of large-scale LEGO Icons sets like the Eiffel Tower (10307) or Titanic (10294).

At $799.99 for 10,001 pieces, the Sagrada Familia set costs 27% more per piece than the similarly sized Titanic, reflecting its ornate sculpting and unique color range.

Common Questions

Does the Lego Sagrada Familia set include detailed interior features?

Yes, the set includes a partially accessible interior. Builders can lift off sections of the roof to reveal the basilica's iconic branching columns, an altar, and stained-glass window effects. However, it does not come with minifigures, maintaining a focus on architectural authenticity.

How long does it take to build the 10,001-piece Sagrada Familia set?

The estimated build time is between 40 and 50 hours for an experienced builder, assuming a steady pace of about 200–250 pieces per hour. The set is divided into modular phases that correspond to the real basilica's construction stages, allowing builders to pause between sections.

Is the Lego Sagrada Familia the most expensive Lego set ever released?

No, with a retail price of $799.99, it is among the most expensive, but the Ultimate Collector Series Star Wars sets—the Millennium Falcon (75192) and AT-AT (75313)—both debuted at $849.99. The Sagrada Familia is, however, the highest-priced LEGO Icons architectural set.
