About Basic

The LEGO Basic theme, which began in the 1970s, was designed to be a more general, non-thematic series of sets. Unlike the themed sets that revolve around specific stories, characters, or concepts (e.g., space, city, or pirates), the Basic theme provided a collection of standard LEGO bricks and pieces, often in a variety of colors. The goal was to encourage free building and creativity without the confines of a specific theme or narrative.

Basic Sets are the basis of any LEGO collection. The contents are so varied that children can build whatever they imagine. And if they need some inspiration they can find it in pictures on the boxes. Unlike Basic Sets the Model Sets are designed to build a particular model from simple instructions. But imagination will create other models from the same bricks.
