LEGO Icons (primarily the Modular Buildings Collection)

Lego Modular Buildings (stylized as LEGO Modular Buildings) is a series of Lego building toy sets introduced in 2007, with new sets usually being released annually. Created in response to feedback and suggestions from the Adult Fans of Lego bricks (AFOL) and Teen Fans of Lego (TFOL) communities, the sets in this series are generally intended for more advanced builders. Although the sets are still scaled around the minifigure and depict town and city life, they are much more complex than traditional Legoland Town/City sets; they contain more than 2,000 total pieces and make use of unorthodox building techniques not usually used in previous official Lego sets. In contrast to most Lego sets aimed at children and adolescents, the suggested age of most sets in the Lego Modular Buildings series is 16 years or older. The Lego Modular Buildings sets have been received with positive reviews and are considered by Lego designers and fans as an "adult collection".
