Green Desk, the short-term office space company now run by Jack Guttman, is growing like weeds. The company started out at 155 Water Street in 2008 and then expanded to 68 Jay Street last year. And as we reported recently, the company is in the process of converting the former Prague Kolektiv space at 143 Front Street into a retail concept called Shops@GreenDesk. That’s not all, it turns out: A new office location is currently being renovated at 149 Prince Street, just off Flatbush behind The Toren. It’ll be interesting to see if this new location flies. It’s clearly not as desirable for the creative set as Dumbo. GMAP
