I am late to this conversation, but I have some teak to sell after I changed my mind about our flooring. It’s not the same pattern as Haddon but it is a parquet and it’s never been installed.

Custom ceramicist in you region might be an option? A feature can also be made of multiple tiles that are pre-mounted as one so easier installation into the field tile. Don't know where you are but we are involved with the tile artisan community, which is vast. Depending on what you are envisioning, likely someone can make it to your specifications. We actually have an online group for Tile Trade Artisans and would be happy to post your vision. Send us a message if you like. (Note, we are leaving for a tile industry conference tomorrow and won't respond until later next week).

Sonoma Tilemakers Stellar line. I just finished a bathroom reno and used Sonoma Tile and I’m very happy with it.

This picture is from an episode of Christina on the Coast, I am looking for the blue and white tiles that are above the stove. Thanks!
