Abatement has started at 27-49 and 27-51 Jackson Avenue following demolition permits filed with the Department of Buildings in late December.1 According to signs posted on the buildings (seen below), abatement began Jan. 5, and will wrap in April.
The buildings formerly held a fortune teller and a deli on the ground floors, and are sandwiched between a rising Aloft Hotel and an Uber. Nothing has been filed in the DOB bin in regard to what the buildings will turn into, but it will likely be a mid-rise, mixed-used building based on the other buildings going up on the block.
LIC Post was the first to spot the demolition permits.2

From what I understand that’s Uber’s New York City headquarters.
