Two high-end department stores Rokin 21 and Rokin 49 are rented by the Canadian Hudson's Bay Company (HBC), making this their Dutch headquarters. Both buildings have a new façade, which has been designed to blend in with their historic location. Authenticity is achieved with 3D curved aluminum façades and curtain walls housing enormous windows. The storefront display windows on the ground floor are 4.5 by 3 meters. A collaboration between Boon Edam and Stackdoor has resulted in an impressively tall entrance through a glass Tourniket original revolving door with a height of 4.3 meters.
