Gorgeous home...congratulations! I am currently struggling with a floor finish choice. The floors are rustic red birch. Finish choices are Tung Oil, which yields a golden, warm tone as in your photos OR polyurethane, which is cooler, more neutral. Like this house, the kitchen is contemporary with walnut cabinets (I am adding some white) but unlike this house, the rest of the house is more traditionally. Would greatly appreciate your input.
