The last remaining condo unit at the 123 Fort Greene Place conversion is now gone, developer Barrett Design & Development LLC told us. The six-unit development launched in February. The last unit was a 1,888-square-foot duplex asking $1,525,000. No word yet on the final price. UPDATE: The unit entered contract at ask. The developers received the final Certificate of Occupancy early this week and will begin closings and occupancy in just a few weeks.
