This is a commercial building that concludes Natiënlaan, the ‘red carpet’ of Knokke. The business complex building is designed as an extension to an existing business site. A substantial green strip provides a buffer towards the village centre of Westkapelle. The business complex building is the first step of the completion of the third phase of the business site. The premise for the design was, on the one hand, to create a landmark, whilst also creating modularity and flexibility, accessibility and sustainability. The building has an exemplary function and is the symbol and the beating heart of the business site. The business complex building houses an ever-changing mix of businesses. By using a logical column structure, fixed cores for circulation and mechanics, light acoustic walls and a modular façade construction, a plan has been developed that evolves with its users.
