Immaculate Conception Parish School is a great example of adaptive reuse, where the original Roman Catholic church west down Lafayette Avenue is now long closed, so the need for its nearby education building was no longer needed. It has been converted into apartments.
This is actually not designed by famed school architects William B. Ittner or Rockwell M. Milligen, but by a follower clearly influenced by them, Henry P. Hess. It opened in 1926. Hess worked for Isaac Taylor, among others, before becoming an independent architect.
