The Fellsmere Public School, the first masonry school building in what is now Indian River County, was constructed during 1915 and 1916 at 22 South Orange Street. The 22,680 square foot, two-story school with a raised basement was designated by Frederick Homer Trimble, a former Methodist missionary architect who had worked in Fuzhou, China. Trimble, who began his architectural career in the United State in 1915 with the Fellsmere School, designed several building in Fellsmere and Vero Beach, and over 150 buildings in South Florida. Trimble also designed the first buildings at Florida Southern College in Lakeland. The school was refurbished and now houses the City of Fellsmere offices.
