BLOX opened its doors on the Copenhagen waterfront in 2018. Funded and built by the philanthropic association Realdania and designed by Dutch architects OMA, the building is a programmatic mix of functions that creates a new destination in this very central and challenging location. BLOX hosts the Danish Architecture Centre and also BLOXHUB, an interdisciplinary environment promoting innovation and sustainable urban development. This monograph offers an in-depth look at the project and its context, and includes essays by Aaron Betsky and Carsten Thau, plus conversations with representatives of OMA, Realdania, and the Danish Architecture Centre.
