Alexander and Alma Oppenheimer Halff House. Built in 1904, this was the home of merchant, banker, rancher and civic leader Alexander Hart Halff and Alma (Oppenheimer) Halff, both members of prominent local families. This imposing residence was designed by C.A. Coughlin and Atlee B. Ayres and merges late 19th century architectural elements with early 20th century modernism. Features of the house include a pressed metal roof and boxed eaves. The family lived here until 1963. Recorded Texas Historic Landmark - 1997 #112
