Electric power was all the rage from the 50s onwards and showing the usefulness of electricity (especially nuclear produced electric power) was the hallmark of a mid century home. Designers tried to pack as much technology as they could into the houses. Here are some of my favorites:

Built-in butcher block, with diner-style backsplash:

Nu-Tone KitchenCenter (basically a blender/grinder/juicer etc built into the counter top):

Built-in toaster:

Triple Sink (all the more space to stack dirty dishes!):

Dual under-counter Sub-Zeros (not the most practical arrangement, but novel):

All of these come from the same 1959 house, which I think was high end for its time. Sadly I think it’s getting torn down.

Another place I saw had an ingenious electric cooktop system that stowed individual coil burners up towards the wall when not in use - flipping down when time to cook. Not necessarily the most usable contraption when space is needed for larger pans (especially woks) but novel all the same.

There’s less original novelty in our house - with the exception of the Mystery Hole, which will get an entry all of its own.
