Twin Tower 'Norra Tornen' in Stockholm wins the International Highrise Award 2020

The final of the International Highrise Award (IHP) 2020 has been decided: The winner of the competition for the world’s most innovative high-rise is the ‘Norra Tornen’ twin towers project in Stockholm/Sweden designed by the Office for Metropolitan Architecture (OMA) in Rotterdam.
The prize comes with 50,000 euros and a statuette created by internationally renowned artist Thomas Demand.

The Norra Tornen twin towers, the "northern towers", are located at the transition from Vasastaden, a district with residential developments mainly from the 1930s, to the newly emerging district of Hagastaden and create a gate situation to the left and right of the arterial road Torsgatan. A gate formed by two high-rise buildings is a motive traditionally used in Stockholm's cityscape to mark important points.
 
In the immediate vicinity of the Karolinska Institute, which annually determines the winner of the Nobel Prize in Physiology or Medicine, Hagastaden is currently Stockholm's largest urban development area comprising 96 hectares, about three times the size of the famous old town. By 2030, around 50,000 workplaces and 6,000 new apartments are to be created here, 3,000 on the Stockholm side and 3,000 in the subdistrict of Solna. Norra Tornen is therefore not only situated at the transition of two districts but also of two municipalities, without this being noticeable on the spot.
 
Norra Tornen marks the transition to the new district and clearly represents a contemporary and sustainable vision for the city. At the same time, the towers are able to incorporate Stockholm's older architectural structure in their color scheme
and rising shape. This mediation between the old and the new is one of the great design strengths of the project.
The sheltered balconies and the cube-like modules alternate in a regular pattern and form a brutalist game of deception. The ribbed structure and coloration of the precast concrete elements were analyzed in many tests. Some versions envisaged uncolored concrete or a manually chipped, rough and jagged rib surface in the style of the design models of 1960s brutalism such as Paul Rudolph's Art + Architecture Building at Yale University in New Haven. With the soft brown of the implemented solution, the façade blends in perfectly with Stockholm's earthy color range, which includes all shades from beige to red.

Sustainability

The "Norra Tornen" have an energy-efficient sandwich façade with 23 cm thick thermal insulation and triple-glazed windows without transoms and mullions to avoid thermal bridges. A natural ventilation of the living spaces is achieved by ventilation elements in the façade panels. Further technical building equipment such as a heat recovery system, heat exchangers in each apartment or commercial unit and the connection to the district cooling system contribute to the sustainability of the towers. The grey water produced is also used for various purposes. The good connection to public transport is an important part of the design of the building ensemble.
