Late summer seems doable. In a couple of weeks the top floor will be poured, and exterior material and inside work will start. With it only being 4 floors, could be open by September.Perhaps late summer/September maybe? Doesn't look like they've started interior fittings at all yet.
I think it could look good as long at it is uniform and doesn't have some off-colour mullions (mullions are okay if the same colour as panel). The more simple they go, i think the better it'll look in contrast to the Simmons building.
