Modular Buildings is a series of Lego building toy sets introduced in 2007. Created in response to feedback and suggestions from the Adult Fans of Lego (AFOL) community, the sets in this series are generally intended for more advanced builders with most sets containing more than 2,000 total pieces and making use of unorthodox building techniques which have not been tried before in official Lego sets. In contrast to most Lego sets which are aimed at children and adolescents, the suggested age of most sets in the Modular Buildings series is 16 years or older. The Modular Buildings sets have been received with positive reviews, being considered by Lego designers and fans as "toys for adults". The sets include Market Street, Cafe Corner, Green Grocer, Fire Brigade, Grand Emporium, Pet Shop, and the newest one Town Hall.
