Awsumb’s most notable works are grand public buildings and places of worship. Awsumb is credited with designing "some of the most beautiful churches in the South," including Idlewild Presbyterian Church, called “the South’s Cathedral of Presbyterianism.” He designed several buildings which are listed on the National Register of Historic Places for their architecture, including the Dermon Building and the Baron Hirsch Synagogue in Memphis, Tennessee, and Dorchester Academy near Midway, Georgia.
