Check out this house in Texas. It's quite opulent, thanks to its use of different materials (stone, wood, metal, glass) on both the interior and exterior, however the quality of work done looks phenomenal. The stone work brings interest to the space, and matches well with the dark wood floors and accents. Not often to you get to see a perfect view of the back of a staircase, and it definitely is a cool design feature.
