While most ongoing projects in booming Long Island City involve ground-up construction, 5-33 48th Avenue, two blocks east of the East River, is a conversion of the type more commonly seen in the borough across that river. The renovation and expansion of a four-story manufacturing building into a seven-story residential property is well underway. The project will feature 36 units, as well as retail at the ground floor. Joseph A Sultana of JLS Designs Architecture is indicated as the general contractor on the project’s work permit.
