A tony Long Island town just got approval to hit the gas on its plan to bulldoze a $26 million mansion on a billionaire-lined block and turn it into a public beach parking lot. The Southampton Town Board on Tuesday unanimously green lit the deal to purchase the three-story, 11-bedroom castle on Meadow Lane from owner Frances Katz. Southampton officials approved the purchase of a nearly $26 million three-story, 11-bedroom, beachfront mansion. “[It] will further provide public access to the beach and the Atlantic Ocean, thereby providing active and passive recreational opportunities for town residents,” she said. Plans to bulldoze the mansion and turn the ultra-exclusive oceanfront lot into a parking area are still months away, according to town officials.
