I think you could argue the new Biogen HQ is out of the ground but I can't think of any others. If Fenway Center gets rebooted as apartments/condos or something else it would be rising quickly but that's a big IF right now.
Not sure what this means for the future of the parcel, but I heard from a source that the entire development team at HYM responsible for the lab building was fired. Maybe they will try to sell off that piece or wait and see and come back with a different proposal but luckily that ugly lab...
