In 2013-2014, the library underwent a complete redesign and renovation, working with the firm of Engberg Anderson.
The building was not expanded, but redesigned to make the most efficient use of the space for the public. Improvements and additions include: a completely redesigned Youth Services department with a focus on active play and learning; a Business and Technology Center, featuring a MakerLab, digital creation studio, computer lab, study rooms, media:scape collaboration spaces, 10 person Conference Room, and Business Cubicles; improved and refurnished Meeting Rooms and Zimmerman "Smart" Room; a redesigned Customer Service area and Internet Cafe.
The Library held "The Remix," its grand reopening celebration, on Sunday, June 22, 2014, welcoming 1,200 guests for a ribbon cutting, library tours, live music, local food, and much more.
The Barrington Area Library was one of six libraries featured in the Illinois Library Association ILA Reporter magazine’s 2015 annual issue on new library buildings.
