The Yettel headquarters in Törökbálint—formerly the Telenor headquarters—was a pioneering example of the “New Way of Working” approach in Hungary. Designed by ZDA as a greenfield development, the project aimed to create an environmentally responsible and collaborative workplace that translated the values of Scandinavian corporate culture, employee equality and communication-based working practices into an architectural environment adapted to the Hungarian context.

In the mid-2000s, this approach represented a radical departure from prevailing Hungarian office culture, which was still largely defined by rows of individual workstations. By contrast, Telenor House introduced a diverse range of flexible workspaces designed to support both focused individual work and intensive collaboration.

The building’s nine office wings are arranged in a fan-like composition around a glazed, full-height central atrium. This articulated plan allows the large headquarters building to maintain a continuous relationship with its natural surroundings. Each floor accommodates office units for approximately 50–60 employees, combining open-plan workspaces, extensive glazing overlooking the landscape and enclosed meeting rooms to provide environments suited to both collaborative and concentrated work.

The full-height atrium forms the social heart of the building. Dynamically curving white circulation bands connect the office units and serve not only as functional elements, but also as defining architectural gestures within the interior. Together, the communal spaces, contemporary artworks and the building’s integration into the landscape give tangible meaning to the concept of a workplace closely connected to nature.

The headquarters’ technical systems also place a strong emphasis on sustainable operation. The building is heated using geothermal energy, and at the time of its completion it incorporated one of Hungary’s largest renewable-energy-based heating systems. These environmentally conscious engineering solutions are fully integrated with the building’s humane spatial organisation, founded on collaboration, openness and social interaction.
