Maybe this isn't the right place to ask, feel free to redirect me.

I'm wanting to re-do my kitchen floor and I'm thinking about doing some custom parquet (I've got A LOT of time on my hands)

There are some floors in town that I know of which appear to be face-nailed boards, but with the face nails countersunk, and the countersunk hole filled with a cut plug. The floors I've seen like this aren't parquet, but the plugs add a nice look to the floor, and I'd think if a slightly dissimilar wood was used for the plugs you'd get a really lovely contrast.

Is there a specific name for this kind of floor attachment (the face fastener with plug over it)? I'm trying to do some research to find out if there are any special considerations needed for installation (beyond what is generally required for any hardwood/parquet), cutting the plugs, etc, but I can't really find any good descriptions of this style.

Thanks!
