Real Estate

The new Flatiron District development prioritizes biophilic design principals.

Seaview Terrace is Newport’s largest privately owned Gilded Age mansion. But you might need to call Ghostbusters before you move in.

The striking modern home is the last one ever built by renowned architect Pierre Koenig.

Consider it the year’s priciest two-for-one.

Make an offer that the owner can’t refuse.

The striking, 20,000-square-foot estate has a guest house, tennis court and sprawling pool pavilion.

The tropical retreat has a 7,000-gallon saltwater fish pond, a 1,000-bottle wine cellar and a deep-water dock.

It’s also got a helipad to help make commuting a snap.

Poised to become the most expensive sale in the US, the 21-bedroom mansion comes with stellar views, a nightclub and a “philanthropy wing.”
