The renovation of Rijkskantoor B73 brings together three ministries under one roof in a future-proof, biophilic environment. MOSS developed the integral green design, with sustainability and well-being as guiding principles. At the heart of the transformation lies the Orangerie—a lush indoor landscape connecting two revitalized pavilions. Acting as the building’s “green lung,” it enhances air quality, improves acoustics, and supports a healthy indoor climate with a wide selection of diverse plants.
