If you’re looking for a unique dwelling to lay your head in Long Island, NY, Sotheby’s International Realty has this $12 million waterfront mansion listed… sporting an X-shaped design.

The luxury home, built in 2004, was designed to bring in more light and views, according to Zillow, with every major room boasting three walls facing the outdoors. It was built solely from cement and imported stone, “like a fortress,” said listing agent Nikki Sturges. “It’s just done magnificently. It’s a house with quality, quality and more quality.”

The 16,754-square-foot home has 8 bedrooms and 13 bathrooms. Features include gold-leaf ceilings, a putting green for you golfers, and views of the water.

There’s also a large indoor pool and spa with mosaic tile opens up onto a lanai with electric screens for shade and privacy; and sits on more than 2 acres, with 380 feet of water frontage, a dock and a boathouse.
