Left to right 17'-10" back to front 12'-10". Both measurements include the cabinetry (including wall cabinets on the left).

What is the brand & color of these floors? Where can I buy them?

The floors are a actual 3/4" hardwood planks in mix of hickory and pecan (very similar woods). They were finished in situ, so it is a lumber product that the hardwood floor installer provided, not a retail brand. That is not to say you shouldn't be able to find them, it is just that i don't have a specific brand. The finish is natural. I am sure a good local installer or supplier could tell you where you could get the wood.
