Architect Bill Peterson bought this triplex condo in 224 East 14th Street in 2008 and gave it a very unique renovation, sheathing the ground floor in a perforated metal screen and outfitting the second floor with a fully-retractable facade/wall that flips open like a garage door, the effect of which is that the owner, if he or she chooses, can sit around a living room with no street-facing wall. That actually doesn't sound like all that much fun, but the design and execution are still very cool. There's a similar garage door wall in the back of the first floor, which opens onto a private garden with a cabana.
Peterson tried to the apartment in 2012 for $2.5 million, apparently didn't drum up much interest, and has now re-listed it for $2.1 million. Considering that he spent $1.8 million plus whatever the renovation cost on the space, it doesn't sound like he's in line for much of a profit, but at least he landed his work on the cover of New York Magazine and in Elle Decor's "Pick of the World's Most Beautiful Homes" list.
