There's a FLW design, the Meyer May House, in Grand Rapids; a block east there's another design that was done by a protege. The May house was fully restored about 25 years ago (they even demolished an addition that held a more modern and better kitchen) and it has one of those FLW-style seance dining rooms.
The Sowden House is Mayan Revival (it sez here) but the floor layout and the organization reminds me more of a classical Roman house.
