50 Shades of Grey, the
erotically charged mommy smut supremely important tome that sparked a nationwide debate about the First Amendment after having been banned from certain public libraries, takes place in the penthouse of Escala, a fancy Seattle condo tower with amenities such as a spa, yoga studio, catering kitchen, 140-person dining area, and dog run. Despite the building's 70 percent occupancy, these 5,200-square-foot penthouses—which, let's face it, Christian Grey and Anastasia Steele enjoyed quite a bit in the E. L. James bestseller—are on the market for $4M to $6M, according to Zillow Blog. Superfans know about this: right when 50 Shades of Grey was first released a year ago, a building rep started getting curious calls about "the layouts of the penthouse and the details of the condos."
Keep in mind that Escala isn't the only place lovers of great literature might call home: the English country house that inspired A.A. Milne's iconic Winnie the Pooh series is also on the market.
