Guinness World Records confirmed the April 12, 2026, attempt on September 25, bringing the five-month-old LEGO challenge into the official record.
The achievement is easy to describe and harder to picture. The LEGO Art World Map , set 31203, contains 11,695 pieces. Much of its surface is a mosaic of small round elements that become land and sea only when many plates are joined. LEGO says the finished work measures 40.5 inches wide and 25.5 inches high. It is designed to be arranged with different parts of the world at its center.
Leong and Swift did the build together on April 12, 2026, at Brick by Brick Toys in Hayward. Guinness World Records confirmed the two-person title on September 25. Its published time is 4 hours, 59 minutes and 51 seconds. That puts the finish just nine seconds inside the five-hour mark.
The verified result and the earlier account
An earlier on-site account by The Pioneer , published April 20 while Guinness verification was pending, reported 4 hours, 59 minutes and 50 seconds. The one-second difference is small, but it matters for a timed record. The reason for that difference remains unclear. Guinness's subsequently verified figure is the one to use for the official result. The April story still provides valuable firsthand detail about the attempt and preparation.
A map built as a team
The product itself explains why the strategy mattered. LEGO says the map uses 40 interconnecting base plates, divided into three sections in its instructions. Each plate can be filled before being joined to the larger work. At this scale, sorting and sequencing are part of the task, not simply preliminaries before the real build.
According to The Pioneer, the friends spent roughly a month practicing, with the final week devoted to intense refinement. Their approach was to work through one color at a time, then connect completed portions like large puzzle pieces. Swift explained to the paper that having each color ready to hand reduced the time spent searching for the next piece. The pair had to divide the work, keep their sections compatible and still finish with a complete map.
That account gives the record its most interesting dimension. It was not a race to place one tile quickly. It was a repeated, shared solution to a problem with thousands of small decisions. Practice made the placement more predictable. Working by color reduced switching between piles of pieces. Working in sections let two builders make progress at once. Those advantages are an interpretation of the documented strategy and the set's design, not a measurement of how much time any one choice saved.
The same distinction keeps the record in perspective. Guinness calls this the fastest time to build the World Map as a team of two. It is a separate title from an individual build. A team has more hands, but it also needs a way to coordinate them. Guinness's account notes that the pair surpassed the time of the individual record holder, while making clear that the individual title remains separate.
Leong proposed the challenge after looking at the record standard, according to The Pioneer. Both builders described a longstanding affection for LEGO, and Guinness reported that the two had connected over that shared hobby. On the day, they put on headphones and worked in a public toy store while shoppers could see the attempt. The result was a formal record built from something familiar: friends making time for an ambitious project together.
Why this particular set works for the story
The World Map belongs to the broader LEGO Art series , which turns small elements into displayable images. LEGO's original product announcement describes a customizable map rather than a single fixed picture. Builders can center different regions and choose how to render the oceans. Those possibilities make the set a creative work as well as a high piece-count challenge.
For this attempt, though, the important feature was its modular construction. Forty plates create natural units for rehearsal, division of labor and final assembly. The pair's month of practice turned those units into a plan they could execute under a clock. That helps explain how a project meant for a long, immersive build became a sub-five-hour team record without treating the piece count alone as the whole story.
The original World Map is set 31203. Readers exploring LEGO's current building sets can visit the official LEGO Store on Amazon (paid link). The Store link is a shopping option for the product family, not evidence for the record or a claim that set 31203 is in stock.
Leong and Swift's achievement sits in the meeting point between play and preparation. The official time establishes what they did. The April reporting shows how they approached it. Together, those sources make the record more than a number: a large, colorful map completed through a practical plan and a shared enthusiasm for building.
