What was permitted
An existing 3-story mixed-use building in the Carroll Gardens area of Brooklyn underwent a significant conversion and enlargement.

The permit for this substantial general construction project was issued on August 28, 2026, with an estimated cost of $3,340,000. DYNATEC DEVELOPEMENT INC (GC) is the contractor for this extensive renovation.
