NYC brownstone whose second floor wall rolls up like a garage-door

Architect Bill Peterson renovated this 14th Street townhouse so that the living room wall rolled up like a garage, leaving it open to the street, with an "air curtain" to keep the heat in: "The hardware on the moving wall is custom, and McLaren Engineering Group, the firm Peterson eventually hired, also works for Cirque du Soleil. 'These guys were like magicians,' he says."
