WTB: Parquet Flooring in 1960's dimensions

They're rectangular wooden blocks. Either buy larger blocks and get them retrimmed, get lucky on ebay, or pay a joinery shop to make them up for you.

The latter shouldn't be that extortionate for a few hundred blocks (beyond the timber costs) as it's a very quick to machine type task, thicknesser->table saw->chop saw.

The mismatch in the patina of age will show up though.

Er, don't you just need matching size individual blocks and lay them in that pattern... If you can't find them commercially any decent timber yard will make some for you.

Having spent the whole morning researching this, I have found that the specific size I want has not been manufactured for a very very long time.

Yes I could get some blocks custom made, but with an area of 10m^2. That's a big hassle.

I found a good alternate in a different size:

Suggestion but a fair bit of work.

Consider lifting the blocks from another small room to patch the extended room and relay the first room with new/reclaimed material of whatever size you can get.

We did something on similar line with roof times when the old house was altered. The front aspect looked like it had been there forever.
