The Boston Biz Journal reports the developer as Core Investments, while the Herald reports it as a joint venture between them and Ad Meliora. On Ad Meliora's web site, they list this site, have a brief note on where it is in the process, and then next down the list they say they just acquired the 6-acre plot at 511 Dorchester Ave. That's between Dot Ave and the rail yard and just a few reps from the Andrew T station, and a stone's throw from this development being written about here. Currently completely vacant, I've been itching to see someone do something of some scale here.
