It's been just 14 months since the North Charleston Boeing plant opened, and the company continues to scale out the site.

But the Boeing isn't pausing.

The Post and Courier notes that a nearly 20-acre development is expected to be added for additional space to build 787 Dreamliner aft fuselages. 

Presently the site is gearing up to produce more than three of the modern planes per month by the end of 2013 — a timeline that would intersect with the new aft fuselage expansion.

Update September 6: The Post and Courier has followed up with some more details about the expansion.

In all, the 276,000-square-foot expansion that will add 59% more space onto the main building on the Boeing campus.
