About the Project

In 2018, the Sun Prairie Public Library staff and the Library Board began an exciting journey to expand and renovate the existing Library. 

The expansion and renovation project will include many forward-thinking features including: a geothermal HVAC, a microgrid system with solar panels and battery energy storage, a makerspace, a library of things collection, a dedicated teen space, a larger youth services programming room, an outdoor amphitheater programming space, a local history and interest collection, more study rooms, a larger Friends bookstore and café space, exposure to local art, and an atrium space which will bridge the expansion and existing library. The renovation will add an additional 25,075 square feet to the space, making the renovated building 60,600.  

In May 2024, the Library Board approved awarding a construction contract to Kraemer Brothers, and a budget amendment was approved by City Council, allowing the construction project to begin. Currently, there is an anticipated completion date of March 2026. 

Support Our Project 

Helping us on this journey is the Sun Prairie Public Library Foundation and the generous individuals and organizations throughout the Sun Prairie Community that have contributed to the Capital Campaign. The Foundation has a fundraising goal of $3.5M and to date, they have raised and received pledges for $2.4 M. They are over half way there!
