In 2017, Bjarke Ingels Group (BIG) unveiled its designs for a project in central Copenhagen. The project features an urban IKEA store, a budget-friendly hotel, and residential apartments connected by green spaces. As a significant part of the development, BIG designed two high-rise residential towers known as “KaKtus Towers,” which are linked by a raised public park connecting them. Both towers, with the tallest at 80 meters high, have been completed in 2024.




Kaktus Towers feature 500 "youth rooms" with hexagonal cores. Each level's twist is designed to offer panoramic viewpoints for every unit but also demonstrates a creative economic construction method that maximizes the scheme's net area. The skewed floor slabs of the towers provide a unique architectural form. Additionally, the 495 apartments are designed around a central core.




The public spaces are well-proportioned and connected by terraces and a green roof. These areas include multilevel common areas, outdoor kitchen and grill areas, laundry rooms, cafés, fitness centers, and party rooms. At the podium level, a business square offers a lively connection for walkers coming out of the adjacent Dybbølsbro rail station.
