Couple quickies this week, just to keep you sharp. The questions below were submitted by actual readers. If you've got an answer, another development question, or a sweet, sweet digital photograph, send us a line at tips@curbed.com?or drop a note in the comments below.
1) Gramercy: "Whole buildings seem to have been emptied along Park Ave South. The rental building at the NW corner of E21 has been emptied. All the space above the new Sovreign Bank at the NE corner of E20. Now the building at the NW corner of E20 appears to be just about vacant and demolition has begun at all the ground floor retail. Has there been any news on this?"
2) Upper East Side: "There is a large development site on the SE corner of 72nd and 1st Ave. Any thoughts on what will be built?"
