Taylor Swift is self-designing her new Nashville apartment in a way you might never imagine — unless you’re a 20-year-old with more money than you know what to do with. The country-pop star is having a moat-like pond built around her living room fireplace, and she says she’s considering adding a few exotic koi fish to the opulent centerpiece. While that kind of decor might not be so hard to imagine, the Disney-gone-surreal accoutrements are a little beyond what one might find in someone’s home — even when that home is a 4,062-square-foot penthouse.

Swift gushed to Rolling Stone this week about her renovation plans for the luxurious 18-story Adelicia apartment building. They’re imaginative, to say the least:

”You step on a stepping stone in the pond in order to get on a spiral staircase, which takes you up to the human-sized bird cage observatory,” Taylor told the magazine. “They’re delivering a human-sized birdcage, which I’ll put a brass telescope in. The ceiling of my living room is painted like the night sky.”

Swift can certainly afford whatever she can dream up, home-decor-wise. The singer and actress, who stars in next month’s chick flick “Valentine’s Day,” was ranked No. 69 on Forbes Magazine’s Celebrity 100 last year, having taken in an estimated $18 million in earnings. And this is an especially good week for Swift, whose fittingly named ”Valentine’s Day” soundtrack single, “Today was a Fairytale,” is selling like crazy on iTunes. If history holds, Swift’s sales will skyrocket yet again after this Sunday night’s Grammys broadcast, where she’ll be performing the song — and hoping to turn her eight Grammy nominations into trophies.

Guests entertained in Swift’s new apartment “fantasy world” might include singer-and-Twitterer John Mayer, who was spotted with Swift and friends at a Nashville restaurant earlier this week.

While Swift’s living room sounds like something that needs to be seen to be believed (and hopefully she’ll give a tour when it’s finished), between the water, the fireplace, the fish, the stepping stones, the staircase, and the birdcage, let’s just hope nobody gets hurt.
