I think that you may be looking at what was called the California Ranch when that area of River Edge was developed in the mid to late 1950's. If it looks like there's a boxy shape in the middle of the front facade with a flat roof section, then that's it. Back then, this was a hugely popular and highly contemporary style. Today we don't quite see it that way.

I don't remember the builder's name but I can tell you it was done in other communities as well by a variety of builders. Anything relating to California was "hot" back then as was contemporary styling. I hope this answers your question. You might want to call the River Ege Borough Hall (201-599-6303) and ask for the name of the Borough Historian who, I am sure, can give you more information on this.
