Building Sets are the plain DUPLO brick sets, buckets and boxes of bricks without a story. DUPLO started in 1969, and the name comes from the Latin word for double, because each brick is twice as long, wide and high as a LEGO brick. The studs are made to fit, so DUPLO and LEGO bricks lock together and a builder can move from one to the other. For years the plastic bucket was the usual way to sell them, from the 1980s through the early 2000s, often shaped or printed as an animal, a farm or a circus, and some came as anniversary editions. Later sets switched to cardboard brick boxes with ideas for what to build on the side.
2007 LEGO Sets
2007 introduced the Modular Buildings series with Café Corner (10182) and Market Street (10190), defining a new era of advanced architectural builds. LEGO Star Wars celebrated its 30th anniversary, commemorated by a limited 14-karat gold C-3PO minifigure. New or refreshed themes included Aqua Raiders, Mars Mission, and a modernized Castle line, while Knights’ Kingdom II and the 9V Train system were retired. DUPLO added Thomas & Friends, extending LEGO’s preschool range.
