Thank you! Pic 2 looks great. Btw, what software did you use to make the pics?

I have no idea of what is going into the space as far as funrnishings are concerned . IMO floor color is like wall color it is dependant on many things. I would look at Porcelanosa for over sized floor tiles but those need a really experienced tile setter and they are hard to find.I think in that house tile floors will create an echo chamber like you will not believe , is there a reason you can’t do some other flooring? In this space the sound control is going to be a huge issue so plan on lots of area rugs window coverings and soft furnishings to absorb sound and I personally would do wood flooring for some relief from all the hard surfaces.

@Aaron Xie the website and products are listed on the photo, MSI surfaces. The first is a large wood look porcelain tile, the second a large neutral porcelain tile. However, I like your soft furnishing and rugs are need to going to be abundant to dampen sound as Patricia Colwell noted above. With a large modern space, high ceiling and tile floors it is going to have a significant sound/echo issue. Good luck.

I love your modern home, but i would also consider doing wide plank light wood floors.
