The sales office at Citizen, the new condo building at 124 West 23rd Street, was closed all summer while the building finished up construction. But a few new listings just popped up for the building, complete with model unit photos, which leads us to surmise that the sales office is now open and the furnished model is on display. (So presumably those partial stop work orders have been resolved.) We've collected the model unit photos and some floorplans for the gallery above. There are six active listings, ranging from $2.85 million for a 1,324-square-foot 2BR to $6.55 million for a 2,025-square-foot 2BR penthouse. There are 13 units listed as being in contract.
