This property has been on the market for a while; it had been asking $4.6M but the price has been chopped down to $4.3M. It's one of the Houses at Sagaponac, an ambitious development of modern homes from the beginning of the 2000s, which was intended to serve as a museum of architecture, but never completed.
This house was designed by Hariri & Hariri, who said the house was inspired by Giacometti's sculpture titled "Figure in a Box Between Two Boxes, which are houses." (Hey, sure, why not.) It's an L-shaped one-story house, with two wings surrounding a central terrace with a pool. There is 5000sf with five bedrooms and 6.5 baths. A finished lower level boasts home theater and gym, and there's a separate guest house/art studio, as well as a two-car garage. There's 2.72 acres of land with a tennis court.
We assume the new buyers will be joining the Quiet Skies Coalition, because the house is right next to East Hampton Airport, the major drawback of the property. We tend to think the price is going to drop because of that.
