The Lincoln K-8 School in Peoria, Illinois underwent an addition and renovation to transform the former middle school into a K-8 facility. The $15.7 million project included a two-story addition for grades 1-4 along the north property line and a one-story kindergarten addition to the east. A shared cafeteria and media center were built between the new wings. The design maximized daylight and views of the east bluff through the use of a sawtooth roof and larger windows. Sustainable strategies like a geothermal system and operable windows improved energy efficiency and indoor air quality.
