New Building on Park?! WTF?

A few weeks ago, I came across a bizarre new building on Park by the BQE for sale by Corcoran. It looked to me like a building full of condo apartments, but the Corcoran listing I found said it was a legal 2-family listed at $979k.

I procrastinated in posting this, and now the Corcoran link isn't working, and I can't find anything about it online!  What happened, and what IS this place?
