The One

The One is a 105.2-meter-tall skyscraper in Brussels' Leopold Quarter, built between 2015 and 2019. The twelfth-tallest building in Belgium, it replaces the demolished Europa Hotel and marks the starting point for the urban redevelopment of the area around the Rue de la Loi. The building combines offices, apartments, and retail units, each with separate entrances and independent technical systems. Especially striking is the design of the side facades, which recalls One57 in New York. Randomly distributed, slanted louvers filter the sunlight and give the structure an ever-changing appearance depending on the angle and the time of day.
