Jim Irwin's FORTH Atlanta is close to becoming a city within a city on the Beltline

A $1 billion, 12-acre district on a former Georgia Power parking lot now carries a Mailchimp tower, a 359-unit apartment building and a 196-room hotel.

New City Properties founder Jim Irwin bought 11 acres of Georgia Power surface parking next to Historic Fourth Ward Park in 2018, and the roughly $1 billion district he built there, FORTH Atlanta, is now largely open. The anchor is a 1.1-million-square-foot office tower designed by Olson Kundig that houses Mailchimp's headquarters.

Overline Residences, a 359-unit apartment building by New York's Morris Adjmi Architects, delivered as New City's first completed residential building in the city. The FORTH Hotel, a 196-room tower with a cast-in-place diagrid facade, added a members' social club, four restaurants and a 350-person event space along the Eastside Trail.

Irwin made his name assembling Ponce City Market's 48 contracts and 725 Ponce's Beltline-straddling office building; SaportaReport's Maria Saporta frames FORTH as his most ambitious project yet, a fully self-contained district rather than a single building.

Why it matters

It's one of the largest single-developer districts ever built on the Beltline, and a test of whether a private master plan can function like a neighborhood.

Opening

BeltLine Starts Northwest Trail Segment 3B

Construction has started on Atlanta BeltLine Northwest Trail Segment 3B, a nearly one-mile link from Trabert Avenue to Tanyard Creek Park. The route will bridge Northside Drive, pass through Atlanta Technology Center and under I-75, connecting five northwest Atlanta neighborhoods to the completed Segment 3A and Northside Trail. Atlanta BeltLine lists late fall 2028 as the expected opening.
