Once the govt ctr office tower is built this is priiiime real estate. Next door to a 600+ footer, a couple buildings down from the hub on causeway, bridges the gap between the two. Blank wall and everything just waiting for a tower to rise right there. Its a triangular plot too could be interesting. Then if they return to the original plan with a tower in the courtyard of the court it can be even greater. Then we all know theres tonsss of land around NST. Could make for an interesting modern cluster of towers in the area.
They should build (/ should have built) a tower on top of the building with the arch at the head of Merrimac street too. It's (probably) too young for the facedectomy treatment, but it would be a great podium for a tower.
