I concur. I posted in middle of the night, as I often do........and that was my instinct, but I wanted to look at it later, when fully awake before deciding. I'm decided. The add-on, on top is incongruous to the rest of the building, it's not complimentary at all, it's a sore thumb; and beyond unnecessary, it's undesirable.
I'd have to go back and look at the layouts, but w/o only 4-5 units per floor, I assume they could be laid out to achieve light from 2 sides......
But regardless, the infill construction and extant presence would likely kill the trees now present over the parking at the condo to the east; and certainly make that, as an outdoor amenity space (which I'm assuming it is); rather inhospitable.
