The Erin Village Branch Library transforms a long-abandoned 1849 grist mill into a vibrant, 14,000 ft² community destination through thoughtful conservation and adaptive reuse.

Retaining the original stone envelope, the project introduces new steel structure within the stabilized shell, enabling large, open public spaces on each level while accommodating modern library functions.

A new attic level provides a reading lounge and community space, with dormers framing views of the town and adjacent river valley. The design celebrates the building’s industrial heritage through the reuse of salvaged timber in interior detailing and the expression of natural materials including wood, stone, metal, and glass.

Historic artifacts—including the original penstock pipe, generator wheel, and a recovered millstone—are integrated into the design as interpretive features. These elements, paired with curated displays and a glass floor viewing area, connect visitors to the site’s history.

The fully accessible facility includes barrier-free entry, elevator access, adaptable meeting rooms, and inclusive public spaces for all ages. Delivered in two phases, the project required early stabilization and intensive investigation to inform structural interventions. The result is a renewed civic landmark that supports community life while preserving the character of one of Erin’s most significant heritage buildings.
