The world’s busiest/most popular/most visited/whatever airport, Hartsfield-Jackson Atlanta International Airport, could look dramatically different soon, as a batch of new renderings proves.

HOK — a global design, architecture, engineering, and planning firm — is leading a team that's designing $200 million in improvements to the airport's terminally hectic domestic passenger terminal. It's part of a $6 billion, 20-year expansion and modernization planned for Atlanta's famous Flughafen.

HOK officials tell Curbed that construction will begin later this year. They provided the renderings below as a preview of what airport patrons can expect. No timeline for completion was provided.

Per officials, a few key elements of the design include:

Two 864-foot-long canopies will cover curbside pick-up and drop-off areas, redefining the character of the building as a 21st-century air terminal and protecting passengers from the elements.

At curbside, travelers immediately connect with Atlanta’s green space and city parks through fritted glass panels that depict the forested landscape of the region.

Inside, passengers will be greeted in the redesigned light-filled atrium featuring a park-like setting, lush with plants and a large circular skylight.

The design accommodates both the curb-to-gate weekly business travelers and the leisure traveler.

Expansive windows flood check-in areas with natural light and intuitive wayfinding help to improve circulation.

For further exploration, here's a symphonic new video that helps put the plans in context.
