|Pandomo by Flooring Future|
|Polished concrete by Sexy Concrete Coating (aka AAA Sexy Floors)|
|Travertine tiles by EcoStone|
In the meantime- do any of those options jump out at you? Have you been so crazy as to fall in love with something even though its a little out of the budget and then do whatever you can to make it happen?
PK has two edits:
1) That image from Sexy Floors Coating is not actually polished concrete- but it is what we were looking for from polished concrete
2) Being natural doesn't necessarily mean that travertine is 'green' as it is a finite resource- however it is a green option in that it's not made from fossil fuels and would eventually bio-degrade, unlike some options
