The transformation of Rijkskantoor B73 in The Hague redefines the modern government workplace through a thoughtful fusion of heritage, sustainability, and human-centered design. Studio PROTOTYPE and ZENBER Architects have created a flexible, nature-infused environment for two ministries - Ministry of Economic Affairs and Climate and Ministry of Agriculture, Fisheries, Food Security and Nature- turning a traditional office complex into a vibrant, future-proof workspace that reflects the values of collaboration and innovation within the public sector.
At the core of the ensemble lies the Orangerie- a lush, light-filled green oasis that connects two existing pavilions into the “green lung” of the complex. This central space brings nature directly into the building, serving as both a social hub and a place for reflection. The Orangerie enhances air quality, fosters well-being, and encourages spontaneous encounters and interaction among staff.
The project’s material strategy emphasizes biobased and renewable resources, showcasing circular design thinking. The two brainstorm pods, entirely built from sustainable materials, act as experimental testbeds for innovative products and technologies. Vertical gardens, plant walls, and extensive greenery regulate the indoor climate naturally, reducing CO2 emissions and cooling demands while creating a serene and restorative atmosphere.
Functionally, the interior has been reorganized to enable multifunctional and adaptable use, accommodating meetings, workshops, and informal gatherings. Smart lighting, acoustic solutions, and a fluid spatial layout ensure comfort and flexibility across diverse working modes.
Balancing form, function, and impact, the design honors the historic character of Gijsbert Friedhoff’s architecture while introducing a progressive and environmentally responsible vision. The result is not merely a renovation, but a living ecosystem-a green catalyst for connection, creativity, and the sustainable future of public service.
