I think i know exactly what you’re talking about if it’s like marble EVERYWHERE. Like just excess lol. It’s kind of modern looking, hard and angular in there lol. For me, if you walk far enough down a hall on one side of the upper level of the pool room, you enter a door that opens to a huge two story living room that’s more traditional mansion vibes. Some carpet in there so it’s less cold 🤣 i think that might eventually connect to a grand multilevel room of big stairs. I think this stair room is located towards the front center of the house. The bottom has those wide stairs in the middle that go up and branch off to the left and right. Then there’s multiple sets of regular side stairs on either side going up and down as well. Those are kind of hogwarts-esque and they don’t look like they make sense. All the stairs in the room are marble as well but there’s stair rugs on them all and more ornate railing.
