Mystery construction

If you check behind the building that houses Jackson Hewitt and Payroll Advance on College Avenue, you will find construction.

Concrete block walls were going up today. I had asked a couple people last week what was going on and they did not know. Today I asked one of the workers and he claimed not to know the purpose of this addition to the building.
Do you know?

Update Oct 28: Someone told me that it would be a pawn shop or something similar to a pawn shop.
