Some people dream of owning a castle; Calvin Klein wants to tear his down. Five years after the designer paid nearly $30 million for a gaudy 50,000-square-foot Southampton estate known as Dragon's Head, Klein filed an application this week to demolish it so he can replace it with a more modest (and much more minimalist) 17,500-square-foot number. To lend credibility to the plan, Klein had neighbors Ian Schrager and Aby Rosen write letters to the Southampton Village Board of Historic Preservation and Architectural Review on his behalf. We're not exactly sure how having someone who was in trouble for destroying an endangered bird habitat on his property this past summer bolsters his cause, but we'll keep a good thought for you, Cal! A few more photos of what's been described as "Disneyland on LSD" after the jump.
