A high-rise development, located at Norway’s most important traffic hub in central Oslo, and with fantastic views of the waterfront and fjord-landscape beyond. The idea is to create a landmark sculptural ensemble of towers, yet observe the harmony with the surrounding, low-rise urban fabric of the capital. The three towers of approx. 110, 65 and 55 m height, are arranged along the edges of the site, and the tallest tower is aligned with the existing nearby Oslo Plaza and Postgirobygget towers, while the lower buildings form the link to the city.The three towers have clear-cut and vertical elevations to the exterior of the site, with large openings and setbacks forming windows to selected viewpoints. In contrast, the elevations towards the interior of the site are composed of stacked, glazed volumes, freely arranged to form a prismatic and crystalline appearance. The layout secures the views over the water, not only for the three new buildings but also the city beyond.In between the towers, a two-storey base containing shops and restaurants forms an undulating landscape that connects to street level via ramps, plateaus and stairs. This base creates a calm urban garden, framed by the tall buildings, with recreational space and cafes for the city and the buildings occupants. The towers are designed with a high degree of flexibility to house offices, hotels and possibly housing.
