As Federal-style homes go, this ivy-clad example on North Blvd. in Edgemont has a pedigree that earned it a place on the National Register of Historic Places. An understated bronze plaque displayed discreetly beneath a demilune portico says so, but doesn’t elaborate. The 1925 home’s design is reportedly the work of C.B. Schoeppl & Co., whose efforts can also be found in a NRHP pair on Westmoreland Ave., as well as in a few other older Houston neighborhoods. Listed a couple of weeks ago for $1.9 million, this green-roofed home at the eastern end of the Boulevard Oaks Historic District sits back from — and a bit above — the tree-lined esplanade along North Blvd. But its corner-lot address is a tad shy of the double-allees of live oaks found a half-block to the east, in Broadacres.
