I'm no expert but that looks like oak flooring typical of the 1920's.

Looks like the flooring in my 1924 four square, without the scratches from my idiot dog! Beautiful.

If it is appropriate to the style and age of the home, does it matter if it is original? If you like it, great but if you don't then have it redone in a different color

Thanks everyone! Here’s an additional photo from one of the bedrooms. It definitely has gaps in between, not beveled edges. I’m thinking of having the floor refinished where it’s scratched up (the dogs have not been so gentle in other places) and faded by some doors.

Also I’m not thinking of tearing this out, but actually wondering if more of this wood flooring under the 90s style laminate in our kitchen. If so, then it might be neat to uncover it and see if it can be restored.

I have similar gaps in my 1928 hardwood floors. If those are original, it would cost you a small fortune to replace them with equivalent quality.

In my area the original flooring in kitchens is pine, rather than oak.

In this area, kitchens were often done with maple flooring. For a house built in the 20s, the original flooring might have been linoleum. I wouldn't necessarily expect to find salvageable wood flooring in a kitchen. It would be a nice bonus but you won't know until you get there. Some good spots to check are where the radiator pipes go through the floor and see what you find underneath the original built in.

Old house owner in Chicago here and I agree with einportlandor, oak in main spaces, and maple in kitchen. We have gaps between our oak floors from shrinkage over time which is unfortunate.

Thanks everyone! Interesting info! I didn’t know that about maple versus oak. The consensus seems to be that it’s oak flooring.

Tim- I think you’re right about it being a bit newer than 1920s. Also I found some leftover planks in the basement, which I’m guessing are there from a remodel when they put it in. The stain is a little different though. It kind of matches the front entry closet stain, which interestingly is below the level of the living room flooring…which makes me think they added this flooring on top. Here’s a pic to try to show the height difference although probably doesn’t capture it well.

The parquet flooring is a middle aged addition, perhaps late 70s to 80s is my guess. The dark colored plank is likely the original finish and the lighter color was from a refinish that is a few decades old.
