Couple Gives Up, Lists Unfinished Brooklyn Mansion for $11.5M

After more than a decade of trying to construct their 15,000-square-foot dream home in Park Slope, Joseph and Ivona Hertz have thrown in the towel and put the unfinished mansion on the market for $11.5 million. The couple bought the land on which their "nearly completed residential property" (per the listing) "with absolutely no finishes" now sits in 2000, paying $825,000. What followed was 15 years of code violations, zoning changes, and every type of headache imaginable. At least the shell of the house currently exists, and it does have a two-story rock climbing wall in the backyard, so if that (and a bunch of renderings that look like they were taken from a 1990s computer game) appeal to you, and you have $11.5 million, have at it.
