You may have spent the night in a police station before, but we're willing to bet your stay was nothing like this apartment converted from an old police headquarters gymnasium in SoHo. Originally built in 1905, the Beaux Arts Police Headquarters was designed by architect Charles Gwathmey and was altered into a stunning 6,600 square foot, 4 bedroom, 4 bathroom residence in NYC. Currently on sale for a cool $30 million, hit the thumbs for a detailed look inside. [DesignYouTrust via Inthralid]
