Unit 14BE at 1901 Walnut Street, listed for $2,250,000, is a new construction über-contemporary co-op. The 3,333 square foot home features a 40-foot long living room, a custom kitchen with Wolf, Subzero and Miele appliances, a media room with exotic-wood bookshelves, and office/gym with built-in mirrored closets. The flush, linear lines of light in the ceiling make the space seem more like a museum or Prada retail store than a home, but we doubt you’d complain about that. The four bedroom, four and a half bathroom home is covered in Quarter Sawn Red Oak planking and cork, and located in The Rittenhouse Plaza Building. —Caitlin Connors
