The Ministry of Economic Affairs, KGG, and LVVN complex in The Hague has undergone a significant transformation led by Studio PROTOTYPE and ZENBER Architects. Completed between 2022 and 2025, the 4,800-square-meter renovation redefines Rijkskantoor B73 as a sustainable and future-oriented government office for three ministries. The project prioritizes flexibility, well-being, and environmental responsibility, integrating nature as a central design element. Anchored by the new Orangerie, the redesign merges two pavilions into a lush, biophilic meeting environment that fosters interaction and collaboration. With its alignment to the WELL Building Standard and use of biobased materials, the project embodies a forward-thinking vision for public architecture—one that harmonizes functionality, human comfort, and ecological awareness.
The Ministry of EZ, KGG & LVVN is not publicly accessible, yet it houses four ministries and forms part of the city’s daily life. The collective spaces we designed — the meeting areas, the restaurant, the conference rooms — touch the urban realm.
Interview with Jeroen Steenvoorden of PROTOTYPE
They are located in a transparent greenhouse, originally designed by Dam & Partners, which is now truly green and visually connected to the city. These spaces are open to the view of passers-by, while offering users privacy and comfort — with greenery acting as both filter and connection. By allowing light, views, and vegetation to become part of the interior life, the building invites a sense of connection rather than exclusion.
The transformation of Rijkskantoor B73 in The Hague demonstrates how a historic government building can evolve into a contemporary, human-centered workspace without losing its architectural integrity. Originally designed by Gijsbert Friedhoff and later expanded by Dam & Partners, the structure has now been reinterpreted by Studio PROTOTYPE and ZENBER Architects as a sustainable office environment for three ministries: the Ministry of Agriculture, Fisheries, Food Security, and Nature; the Ministry of Climate and Green Growth; and the Ministry of Economic Affairs.
At the heart of the redevelopment lies the Orangerie, an expansive green courtyard conceived as the social and ecological nucleus of the complex. This space, characterized by lush vegetation and generous daylight, serves as a meeting point that connects employees with nature while promoting informal exchange. Its vertical gardens and plant walls act as living filters, improving air quality and reducing energy demand. The architects introduced two compact brainstorm pods built entirely from renewable and biobased materials, which function as both working environments and testing grounds for circular design applications.
The design’s adherence to the WELL Building Standard underscores a broader ambition to enhance the health, comfort, and engagement of its users. Sustainable choices extend from materials and lighting to acoustics and indoor climate, ensuring a balanced and regenerative workspace. Collaboration among experts ranging from Moss on landscape design to QC Lightfactory on lighting and Melchior Jaspers on art integration brought depth and coherence to the architectural vision.
Completed under the management of the Central Government Real Estate Agency, the project represents a collective effort to redefine the modern government office as an open, adaptable, and environmentally conscious space. Through the synergy of architecture, ecology, and social interaction, the new Ministry of Economic Affairs, KGG, and LVVN complex sets a precedent for the future of public sector work environments in the Netherlands.
