This week we have the island villa belonging to the South Beach Diet creator, a California spread fit for the small screen and a sprawling Manhattan gem built out of a former police gymnasium.

The creator of the wildly popular South Beach Diet is looking to shed some real estate weight by getting rid of his hefty island property in Florida’s Sunset islands for a cool $23 million.

Arthur Agatston, the cardiologist responsible for the South Beach craze, built the smart home in 2009 after paying $4.2 million for the lot.

The mansion includes six bedrooms, seven full bathrooms and three partial bathrooms. There’s a spacious multipurpose room for entertaining diet-restricted guests adjacent to the kitchen, a media room and a sitting room.

Complimenting Miami’s tropical weather, the lushly landscaped outdoor space features multiple terraces, a waterfront swimming pool, a dock, an outdoor dining area, a summer kitchen, and numerous open and covered sitting areas.

The Sunset Islands are one of the four man-made islands outside Miami Beach, and are protected by 24-hour security.

You’ll definitely recognize this small screen gem. A California estate featured in “Dynasty” and “Knight Rider” is hitting the market for $28 million.

The Pasadena villa was originally built by railroad heir and mining tycoon William Kennon Jewett in 1913 as a grand estate removed from the main road by a 100-yard, tree-lined driveway.

The grounds include a pool and tennis court and an array of manicured gardens and lily ponds, one of which set the scene for a showdown between "Dynasty” characters Krystle Carrington (played by Linda Evans) and Alexis Carrington Colby (Joan Collins), which aired in 1983.

The property spans two separate parcels.

The yellow stucco main house includes 13,000 square feet. The mansion has seven indoor fireplaces, a wine cellar, an elevator, five main bedrooms and nine bathrooms.

Beyond the manicured grounds, there’s a 2,430-square-foot second residence or guest house with its own private entrance and swimming pool.

This last property is truly one of a kind—a sprawling apartment in a former police gymnasium that has just hit the market for $18.5 million.

The stunning Nolita four-bedroom architectural gem on Centre Street was constructed in 1909. You’ve never seen anything like the home’s 25-foot barrel-vaulted ceilings with exposed steel trusses.

The historic 6,600-square-foot duplex sits on the fifth and sixth floors, and features a private terrace with views of Lower Manhattan.

The home includes four bathrooms and a half-bathroom. The master bedroom suite is on the first floor with walk-in closets, a private sauna, dressing room and office area. The library, on the second floor, “floats” above the master suite and overlooks the main floor’s living and dining room.

The building also includes a private shared garden, fitness room and 24-hour concierge.
