The first school at 2070 Five Mile Line Road was built in 1907. In 1932, the building was expanded, bringing the now-familiar white columns and gold-capped cupola. The building was expanded again in 1951, adding the gymnasium and classrooms at the rear. This building served as Penfield High School until 1958, when it become a junior high school. The building was completely renovated in 1966, including demotion and replacement of the original 1907 section. Now called Denonville Junior High School, the building was used by Penfield as a junior high / middle school until 1980.
