In 2019, Trees Atlanta, a non-profit whose mission is to preserve and protect the tree canopy of the city, began developing its new headquarters, the Kendeda TreeHouse, on a three-acre site in Southwest Atlanta. The project includes two interconnected buildings, totaling 22,000 square feet, with a focus on functional, flexible interiors. The larger structure, located at the corner of Warner Street and Allene Avenue, houses administrative offices, classrooms, and meeting spaces for the organization's expanding programs. These spaces, designed to support adult and youth education programs, including a popular summer camp, are complemented by modular indoor/outdoor classrooms. The adjacent implementation building provides expanded storage for equipment as the scope of work grows. Designed for collaboration, the office also accommodates three additional conservation organizations. The open-plan workspaces and shared areas foster interaction, while extensive glazing ensures natural light throughout. The campus, adjacent to the Atlanta Beltline Westside Trail, features 1.5 acres of landscaped areas with native plants and newly planted trees. Lord Aeck Sargent led the architectural design as well as the landscape architectural design, balancing the needs of a growing organization with the goal of fostering community engagement.

The design team determined that there were two existing elements on the site that should be preserved: a large Oak tree on the western boundary, and an abandoned grain silo. Both were carefully integrated into the design to celebrate the grandeur of the tree and to connect visitors to the site’s history.
The building design takes cues from the vernacular architecture of the south, creating covered porches and balconies which overlook a newly created meadow. Large overhead doors on the ground floor create flexible indoor/outdoor spaces. The intent is to create a facility that is porous and encourage building users as well as visitors to engage the site. The interior finishes further this intent by connecting the staff, visitors and community to the natural world through carefully created details, colors, textures and branding.
