Ahu and I debated quite a bit about the material to use as flooring in the offices. She wanted stone from the beginning. I wanted hardwood in my office. However, after thinking about it, I realized that stone is the way to go.
My office attire basically consiste of a t-shirt, flip flops, and a swimming suit. I will jump in the pool several times a day as a break. Nothing like a quick dip in the cool water to recover from that post-lunch food coma in the early afternoon. A corollary of this is that I am often dripping wet when I come back to the office. Dripping chlorinated water all over hardwood would be problematic over time whereas dripping on stone is just fine.
Ahu, of course, went for a Turkish travertine tile. She chose a tumbled edge for a more rustic look and a Versailles lay pattern which required many tiles of various sizes and also an extra trip to the Floor & Decor when the original estimated number of tiles came up short.
As mentioned in the drywall discussion, we decided to add ledger stone to the back wall of the office. I think the stone matches the tile floor nicely and adds some great natural color.
