Across Massachusetts, historic buildings are finding new life through thoughtful rehabilitation and adaptive reuse. Preservation Massachusetts has recognized three Epsilon-supported projects with 2026 Preservation Awards, celebrating outstanding examples of historic preservation, redevelopment, and community investment. Together, these projects demonstrate how historic properties can be reimagined for modern use while maintaining the character and significance that make them unique.
Epsilon provided historic preservation consulting and historic tax credit services for each project, helping project teams navigate state and federal preservation requirements and advance the successful redevelopment of these historically significant properties.
