SSOE worked with Delta Air Lines on the renovations to its administrative headquarters lobby and café.

Enhancing Delta’s Brand & Image

Creating an exciting and inspiring first impression for visitors, a space for employees to recharge, and a place to celebrate the heritage of a great company were several goals of the lobby and Woolman Café renovation project. The project supports Delta Air Lines in employee recruitment and retention while drastically enhancing its brand and image. By incorporating natural lighting, furniture selection, finishes and materials, artwork, lighting, and graphics, the newly renovated lobby / café spaces accommodate five services brands, doubled the seating capacity, and demonstrates Delta’s story in a sophisticated and progressive design.

New Hub of Collaboration

The lobby and café work together to create a new employee hub for collaboration, technology, and mobility as well as access to employee amenities including a clinic, fitness center, pharmacy, meeting rooms, and central elevator core for the building. While the lobby addressed Delta’s story, heritage, and visitor reception, the café’s vision is a positive influence on all who encounter the Delta community. The design is fresh, lively, honest, and unexpectedly fun.

Thoughtful & Energized Environment

Converting the existing spaces into this thoughtful, energized environment was no easy task requiring coordination with existing building infrastructure, systems, kitchens, elevators, life safety stairs, and exits. Opening existing exterior walls with large clear windows provides views to the organization’s bustling corporate campus.
