Cortney and Robert Novogratz, the stars of the upcoming Bravo reality TV show “Design Sixx,” have switched real estate brokers in their attempt to sell the townhouse where they live and the show was filmed. The family’s current home, located at 400 West Street, originally went on the market for $25 million in June with Brown Harris Stevens’ Wendy Maitland and Susan Green. This weekend, it was re-listed at the same price with Raphael De Niro, a managing director at Prudential Douglas Elliman. Under the auspices of their Manhattan development and design firm, Sixx Design, the Novogratzes specialize in renovating and flipping abandoned Manhattan spaces, and have moved 11 or 12 times in the past decade, living in houses they flipped. And the couple has seven children — the last one was born in January — which is what prompted Bravo to announce a reality series based on their lives. The show is slated to air this coming January. Reality show or not, brokers have speculated that the house — which comes with a private basketball court — is priced too high, the New York Post reported. [more]
