Hensel Phelps (HP)—a national construction, planning, and facility management company—sought to relocate its Mid-Atlantic office to a centrally-located, modern, and branded office. ZGF assisted HP to develop workplace strategies, facilitate data-driven decision-making, and eventually design a branded environment expressive of the company’s history and culture.

Driven by a desire to accommodate employee growth while increasing its profile, HP first engaged ZGF as it began conversations about its future relocation. By framing fundamental questions and collecting information through employee surveys and interviews, ZGF helped HP to select a location for its new headquarters for the Mid Atlantic Region and to understand how a custom design for its new office could reflect its values while creating a productive and energizing environment for staff.

Following the selection of a location, ZGF designed HP’s new workplace to convey the company’s trail-blazing advancement in the region and the integrity of its construction work. A raw material palette of blackened steel, gun-metal and reclaimed wood, scarlet and gold upholstery, black matte tile, concrete floors, and quartz surfaces was carefully selected to evoke HP’s brand and the high quality of its craft. As a nod to the range of HP’s strength in constructing both high performance buildings and refined interior environments, highly finished spaces throughout the office are peeled back to reveal the building’s underlying bones and systems.

Diverse space types—including open plan work stations, private offices, Skype rooms, large conference rooms, and privacy nooks—provide staff with flexibility and choice, as well as dedicated space for either collaborative or focused work. A third of the open office environment accommodates hoteling, with compact workstations, for staff who are back at headquarters between field assignments. Large, open communal kitchens invite employees to gather for meals or happy hour, while a connected multipurpose room utilizes flexible partitions to support different activities, from training sessions to company events.



Environmental graphic installations and signage contribute to the branded environment and express HP’s legacy as a service provider and builder of some of the country’s most significant projects. A woodblock wall in the reception area honors the individuals who have celebrated 20+ year careers at HP and who have helped to shape the culture of the Mid-Atlantic office. A timeline wraps the interior core walls and graphically narrates the history of HP nationally and in the region. HP’s significant contributions in the DC metro region are represented in a tone-on-tone silhouette graphic in the kitchen. Office, workstation, and room identification provide wayfinding throughout the office.
