Technically, Brooklyn’s booming

Downtown Brooklyn has gone from a 99-cent-store haven to a residential hub — and now a techie hot spot.

With nearby DUMBO and the Brooklyn Navy Yard so packed with tech firms as to create long waiting lists, Downtown has benefited from the spillover.

And now, the city’s fastest-growing residential neighborhood since a 2004 rezoning is reinventing itself again — as a destination for start-up and established Web-design and other high-tech companies.

In the last eight months, 11 more tech firms have arrived — including four leasing a combined 100,000 square feet of space at the MetroTech complex, said the Downtown Brooklyn Partnership.

Among the newbies are MakerBot, which makes 3-D printers, and Homer, a creator of early-childhood apps.

And at least six other firms are in the pipeline to arrive by June at two other nearby buildings, 325 Gold St. and 33 Flatbush Ave.

“We are seeing strong interest here, about three to four calls a week from new businesses,” said Thomas Conoscenti, the Downtown Brooklyn Partnership’s executive director for planning. “These companies especially love the mass transit.”
