ABC7 News' Amanda Del Castillo emceed the Brick Factor competition at Legoland's Discovery Center inside the Great Mall in Milpitas.
The top six competitors participated in formal interviews and a final, San Francisco 49ers-themed challenge.
"After an intense day of competition, Samuel Suksiri from Milpitas was named Master Model Builder of LEGOLAND Discovery Center Bay Area," the company announced Saturday night.
This means Suksiri will be given a full-time position to design and build new store furniture.
"This hands-on position will be responsible for maintaining and developing new features and building new models, as well as working with the thousands of children expected to visit the soon-to-be-opened 31,000-square-foot attraction opening in April 2020 at Great Mall, the largest indoor outlet and value shopping destination in Northern California located in Milpitas, California," a spokesperson said.
The LEGO building competition was scheduled to be a two-day event, but because of the NFC Championship Game happening on Sunday, the contest was condensed to one day.
