Philadelphia's old industrial buildings, like those in many cities in recent decades, have enjoyed a renaissance, as anything but industrial buildings.
What were breweries, clothing mills, tire plants, and electronics factories have been turned into hip apartments and condominiums, airy office buildings, and upscale restaurants.
That's if they weren't bulldozed entirely.
Now comes a movement to reverse that trend, as Philadelphia economic-development advocates hope to revive the city's manufacturing muscle, in part through the national push for more energy independence and the jobs to make that a reality.
The Community Design Collaborative, a volunteer group that promotes revitalization of older, urban neighborhoods, is joining the Philadelphia Industrial Development Corp. (PIDC) on an 18-month initiative to improve job opportunities and restore underused industrial buildings and land to what they call "a competitive market standing."
