Look under the "On the boards" subject. It appears to be an addition to the building that exists with the addition on the 5th street side.

This looks great! I am most excited by the fact that it is a multi-purpose building, with offices and condos. these are much more economically viable. The condo and office markets are not necessarily in synch with one another, so when the office market is down, the building still makes money because the condo market is up, and vice versa. I don't have graphs or anything, but I don't think it often happens that both markets are down at the same time, but maybe someone could point to where I could find this information-?
I did one of these for my thesis project for architecture school (Drexel), on the site that the Symphony House is now being built. My project was a behemoth, 1076 feet tall, comprising offices, condos, and a hotel.
