Heidi Hefferlin, AIA, LEED AP

Founder + Managing Partner



HK Architects Headshots

A native of Chattanooga, Heidi loves the city and its trove of industrial buildings. She’s passionate about rehabilitating and restoring old spaces crafted with two-foot-thick masonry walls, steel-riveted beams and heavy timber. As HK’s founder, she oversees the firm’s day-to-day operations and works as a principal architect on key projects. Her projects have helped
reshape Chattanooga’s urban landscape, and cemented the city’s reputation as a magnet for innovation and adaptive re-use.

Heidi began her architectural career in Los Angeles, working with renowned global agency Skidmore, Owings & Merrill, and then Richard Meier & Partners, and Ellerbe Becket, before launching her own firm at age 29. With experience in commercial, retail, institutional, hospitality, and residential projects, Heidi is committed to design that responds to the individual needs of the client.
