A few days ago one of the SPAN-mailing list members posted a question asking what was going on at 7th Avenue and 42nd - actually, the questioner called it a monstrosity.. The reference was actually to a building on the corner of 8th Avenue and 42nd - 4202 8th Avenue, to be exact. It also takes up two house addresses on 42nd, but the 8th Avenue address probably allowed for the 7 level building plans to be approved. You can see this building from the back here.
This building site has had many complaints, several which specifically mention neighbors' buildings having wall and flooding issues due to demolition and construction. There have also been a couple of SWOs issues over the last year. But now construction seems to be humming along on this 7 level apartment building.
Sorry about the bad photos. Between my camera and the lighting, they pretty much stink. You can read and see more about this site on Sunset Park Matters, a blog specifically about the irresponsible development going on around 11220 and 11232.
