Parquet floor tile went out on the 80's. Do yourself a favor and find something more modern, that will help with resale value down the road. If you are determined to use that stuff, you may find flooring outlet stores or the dumpster behind the flooring store.
I put down a LOT of that oak parquet flooring back when I started, in the early 70's. It went down with a solvent/rubber based adhesive, very flammable. I'm sure that glue wouldn't be allowed today.
I had just trowled out about 12 sq. feet (3'x4') in a halfway when the customer's St.Bernard decided he was going upstairs, thru my glue. It took over 2 hours to clean the glue off the carpeting on the stairs. I let the owners clean the dog. They had "propped" a small gate in the doorway to keep him in the family room and went out .
I charged them double time for the cleanup!
I live near Chicago.
That parquet stuff was big in 60’s and 70’s, mostly in tract housing.
Very groovy and trendy, back then.
It tends to be kind of loose and bouncy.
The individual pieces can shift around like a Rubik’s cube.
Mostly ripped out starting early 80’s.
It also tended to swell and buckle after getting too wet.
