A resident on 47th between 7th and 8th wrote in to Brownstoner for advice on how to handle a "monstrosity" being built next door. The thread has several responses and answers on how to deal with the issue (and subsequent property value drop).
It's a little confusing because the original question states that the block is all brownstone houses, yet the block is actually facing rows of cute brick houses with porches. It's one of my favorite blocks. I always try to walk down it on my way to 8th Avenue, especially when the front roses are in bloom. Let's hope it doesn't turn into what the neighbor fears.
