KupkA is a human-scale tower that has been completely restructured by the firm Yrieix Martineau Architecture. At the cutting edge of technology, it has been awarded the most prestigious environmental labels and certifications: HQE Excellent, BREEAM Excellent, WiredScore Gold, and Well Gold. New dining areas, a fitness center, a business center café with a capacity of 75 people, atriums, and 550 m² of green space are now available at Kupka.

Three main ideas guided the renovation of this building :

• Rethinking the entrance sequence. The new entrance is relocated to the bow and offers a better connection to the slab and optimized enhancement of its main access.
• Revitalizing the façade with the creation of two atriums that offer a view of La Défense from the interior.
• Enhancing outdoor spaces so that users can enjoy private green spaces with a garden and an accessible rooftop.
