They say it's in East Flatbush, this is in the northern end of east Flatbush, apx 6 blocks from Prospect park. The location is interesting because it's further east than developments have traditionally gone. Look out 2/5 lines you're about to get jam packed.
The rendering is nice enough, but I would want to see more windows, the window to brick ratio seems to favor the mason over the glazier. It reminds me of the newly built condos in Dumbo on Plymouth and Jay heading east, they bore a resemblance to Russian Gulags (giant iron garage door that rolled to the side, cement facade, narrow windows).
I'm going to guess since it will only be composed of 2br and 1br, it will probably be nice rentals.
