We've already seen a peek at the outside of Kim Zolciak's new digs, but the mama of four recently posted a picture of the inside. And, wowzers, is it gorgeous.

"My iron is finally go in!! Been 3 months in the making!," Kim tweeted, alongside a picture of a grand staircase in a cathedral-ceiling room. Seriously, is this Kim's house or the Metropolitan Opera House? Holy fanciness!

Kim also shared a picture of what will eventually be her driveway, which will of course include meticulous landscaping and — wait for it — a waterfall!

It's looking absolutely beautiful, but between that railing and a small body of water in her driveway, Kimmie's going to have her work cut out for her with baby-proofing.

What do you think of Kim and Kroy's new castle?
