Supersizing of Dumbo's 10 Jay Street in the Works?

Several years ago the owners of 10 Jay Street in Dumbo filed plans to add a five-story addition to the commercial building. After a few stop work orders were put into place, though, the plans were never realized. This week, however, the city issued permits for “a five story vertical enlargement and one story extension” on the building. It’s unclear exactly what the purpose of the enlargement is or how it’s supposed to look, or if it perhaps represents some sort of residential-conversion gambit. Since the original plans were filed the building became part of the Dumbo Historic District so, unless the original permits were grandfathered in, we’re assuming the enlargement requires LPC approval.
