normal Cleveland duplex floorplan?

[Maxwell Hodgkins]

The wife and I are looking to relocate to Cleveland, OH and buy a duplex. We have been using Redfin as our main reference.

There are a few side-by-side duplexes, but the vast majority are over/under units built between 1890-1920.

Based in the external & interior pics, they seem to share a floor-plan. Even the fireplaces in many of the units look the same.  

Anyone out there have any examples of common "standard" floor-plans for the duplexes in the Cleveland area?
