The Altona Schoolhouse was built in 1880 as a one-room country school to serve the primary education needs of Altona, Colorado, just north Boulder. It functioned as a school until the 1940s when it was purchased by an individual and converted into a residence. Boulder County purchased the surrounding Heil Valley Ranch in 2012 and acquired the historic structure. The Cultural Resources staff of the Boulder County Parks and Open Space spearheaded a historic preservation project to restore the schoolhouse for interpretive and limited educational purposes. JVA helped write a Historic Structures Assessment in 2014 to inform the future use of and treatment recommendations for the building. In 2018, the design team was charged with completing design documents based on the recommendations of the Historic Structures Assessment. The scope of work included architectural, structural, and civil site improvements to recreate missing elements, repair deteriorated finishes, increase the stability, and provide accessibility to the building. Site drainage and access was improved to provide ADA access to the front door. Structural improvements including masonry restoration and strengthening of the roof framing were also completed.
