Eyeball report that J&K's place in Lawrenceville (by Doughboy Square) has been demolished as part of the site prep work for the eventual "Squareview" building. I am guessing since they are only doing excavation now there is no way they will get a foundation in before winter - the Lawrenceville new construction projects are moving slow as molasses over the last year.
Also, riffing on East Liberty, not only could three out of four corners of the Penn/Euclid intersection be a complete urban corner, the same may be true for Penn/Negley. The owners of Penn Plaza also own the Babyland site, and while their previous plans there have been underwhelming to say the least, given their new, presumably more ambitious plans across the street I wouldn't be surprised if they include it in whatever major redevelopment takes place. In addition, I have heard that Monro Muffler is closing and selling to a developer. Their ownership includes the vacant lot at the corner and the UMPC building just behind on Negley, in addition to their building next to the (now vacant) Salt of the Earth building.
I also saw today the Urban League Charter school is moving out of their current home a bit further up on Negley, presumably for the old PPS facility in Larimer they earlier showed interest in. T
he old synagogue they are vacating is amazing, and certainly deserves historical designation if it doesn't have it already. I could see it being a really tough building to preserve given the current redevelopment pressures in East Liberty however.
