Urban Mountain is a refurbishment and extension of a 50,000 m² high-rise office building in central Oslo. The project introduces completely new and innovative ways of reducing energy consumption and the building’s CO2 footprint, employing Cradle to Cradle principles and targeting a BREEAM Outstanding certification. When the refurbishment is complete the building will reach a total size of 79,000 m² and will be a sustainable landmark for the city of Oslo. The building will be the tallest in Norway and the first high-rise building in Norway to enjoy natural ventilation.
