The Post and Courier newspaper will begin relocating its business and editorial offices in mid-July in preparation for development of the second phase of the Courier Square office, residential and retail project.

The move from 134 Columbus Street will mean a more modern and efficient work arrangement for the newspaper’s newsroom, advertising, marketing and circulation departments. Those operations will relocate to 148 Williman St. in Charleston’s NoMo District of offices, technology firms and restaurants.

The Williman Street property is managed by Raven Cliff Company, which has redeveloped and currently owns nearly 250,000 square feet of formerly industrial space in the district named for its North Morrison Drive location.

“We are happy to welcome The Post and Courier to NoMo, a neighborhood which is evolving rapidly to meet the needs of a changing Charleston,” Stephen Zoukis, CEO of Raven Cliff, said in a written statement.

The newspaper’s pressroom, packaging, distribution and transportation departments will move later this fall to the World Trade Center development on Leeds Avenue in North Charleston. That facility will house The Post and Courier’s recently purchased 2008 Goss Magnum single-width press.
