Welcome to Shimer Square

Shimer Square: Honoring History, Building Tomorrow

Shimer Square represents a transformative redevelopment initiative led by the Economic Growth Corporation (GROWTH) to revitalize the vacant former Shimer College campus nestled in the historic community of Mt. Carroll, IL. Committed to preserving the campus's unique character, historical significance, and integrity, GROWTH's revitalization effort emphasizes adaptive reuse and repurposing to create a modern mixed-use development that honors its past.

This year in late summer, GROWTH will begin welcoming new residents into the 51 new apartments, open its Resource Center, and extend a warm invitation to families and individuals to make Shimer Square their home. Additionally, the Early Childhood Development Center will open by a licensed operator, creating vital jobs and expanding childcare availability within the community.

In 2024, construction progressed significantly on the $33.4 million historic, adaptive-reuse conversion of McKee/Hostetter and Dezendorf Halls into 51 studio, one-, two-, and three-bedroom apartments. Construction on the $2 million Early Childhood Development Center began in October 2024. Both projects will be completed in summer/fall 2025, with the childcare center completion being first.

In 2023, construction commenced to enhance various facets of the campus, including preserving the campus' iconic front entry gate, implementing infrastructure improvements, and rehabilitating and adding accessibility within the Sawyer House, which will open to the public as a Resource Center at the same time as the apartment and childcare center completion. A feasibility study conducted in 2023 overwhelmingly supported the establishment of an early childhood development center at Shimer Square for families residing within a 30-minute radius of the campus. Additionally, plans were solidified for the development of 51 new apartments.

As the story of Shimer Square continues to unfold, we invite you to be part of shaping its future. Reach out to discover how you can contribute to this vibrant community, where history is cherished, and every moment reflects our shared heritage.

$33.4 million investment and 51 new apartments under construction, opening in 2025

Construction is underway on GROWTH's $33.4 million rehabilitation and redevelopment of the McKee/Hostetter and Dezendorf Halls.

  • community room
  • game room
  • library area

Stabilizing for Future Development: Hathaway Hall

Hathaway Hall took a significant step forward with the installation of a brand-new roof. This crucial improvement not only enhances the structural integrity of the building but also sets the stage for future redevelopment endeavors. With this essential upgrade in place, Hathaway Hall is poised to undergo further transformations, ensuring its continued relevance and contribution to Shimer Square's vibrant landscape.

Resource Center, opening 2025 

Renovation and construction efforts commenced on August 21, 2023, at Shimer Square in Mount Carroll, IL, driven by a $1.5 million investment sourced from Rebuild Illinois support. As we complete this transformative project, the impact of this investment becomes increasingly evident. The work undertaken has been comprehensive, encompassing general renovations to the Sawyer House that is being converted into a Resource Center, replacement and adding parking lot and sidewalks, masonry repairs to Shimer Square's iconic main entrance gate, asbestos removal, and interior building demolition within Bennett and Hathaway Halls.

Notably, the Rebuild Illinois grant-related construction officially kicked off our revitalization effort at Shimer Square, and reflects our commitment to revitalizing this historic site, ensuring its continued relevance and vibrancy within the community for years to come.
 

In 2024, the Resource Center will be used as a construction office for Growth General Contracting, LLC and GROWTH as construction continues within the campus and will officially open to the public in 2025.

Commencement Celebration held on May 28, 2022 where Mayor Carl Bates introduced Brian Hollenback, President/CEO for GROWTH who took the time to update the community on development updates, that construction soon begin. “Our first commitment was to bring Mayfest back to the Shimer Square campus. It only makes sense that three years later, after one intervening pandemic, we come back to Mayfest to update the community on our good news, and to assure the same community that GROWTH is working hard behind the scenes to advance the shared plans that are starting to be realized for this historic campus.” ~ Brian Hollenback, President/CEO.
