Despite its lengthy building history, the church complex has maintained a remarkably coherent character. Working from pattern books, local contractors Matison P. Baker and Frank L. DeShong built the Gothic Revival church in 1890 of dark brown brick with stepped corner buttresses that extend above gables (pinnacles removed in 1920), pointed-arched windows with the finest wood tracery, and a three-stage corner tower with a steeple. Shirley Simons added an entrance on S. Bois D’Arc Avenue in 1941 and a chapel and classrooms in 1950. Dallas architect C. D. Hill added an educational wing in 1923. A 1984 plain Postmodern addition was designed by Simons-Clark Associates, successor firm to Shirley Simons.
Christ Episcopal Church (1918; 118 S. Bois D’Arc Avenue) is a much simpler Gothic Revival scheme, with a five-stage square corner tower. Recent expansion on the compact site added the Grelling-Spence Building (2009, Butler Architectural Group), which is compatible without mimicking the older structure.
