A major Atlanta developer is forging ahead with a major expansion of its signature hometown project.

Jamestown is set to expand Ponce City Market in Old Fourth Ward by 500K SF, including a new 100K SF, four-story, timber-framed office building, 38K SF of retail and restaurants as well as a 400-unit “hospitality living” concept that will offer short-term and long-term apartment rentals.

Jamestown also plans to expand its Central Food Hall, transforming some former office and retail space into four kiosks and a bar, the company announced this week.

The apartment project's “hotel-like services” will include housekeeping and laundry. The development also will include a pool and a rooftop terrace. The rooftop at Ponce City Market, called The Roof, has become an attraction at the development in its own right and includes a bar and restaurant.

This is the first major expansion of the former Sears multistory warehouse since it opened its doors in 2013 and became one of the city's most popular mixed-use destinations. Key office tenants there include Industrious and Cardlytics. Mailchimp recently announced that it would move out to anchor New City's $300M 760 Ralph McGill Blvd. development after it was unable to expand further at Ponce City Market.

“Ponce City Market has been a transformational, historic redevelopment for the neighborhood, city, and region,” Atlanta City Councilman Amir Farokhi said in a release. “What is happening between North Avenue and Ponce de Leon and along the BeltLine's Eastside trail is not just meeting demand, it's good urbanism executed with excellence.”
