Arup has been appointed to develop a 21-storey tower that will be the world’s tallest wooden residential building to date. The 73m-high Haut building will be built in Amsterdam in the Netherlands and will include 55 apartments and an underground car park. It will have a total gross floor area of approximately 14,500m2 and is designed to receive the BREEAM Outstanding label, the highest possible sustainability score. Arup will work in partnership with Lingotto, Nicole Maarsen, Team V Architecture and Nederlandse Energie Maatschappij. Using wood provides an answer to the Municipality of Amsterdam’s quest for CO2 neutrality, said Arup. Haut’s wood can store over three million kilograms of CO2. In addition, 1,250m2 of solar panels will help the building produce renewable energy, while wastewater is purified through a constructed wetland on the roof. The parking garage in the building has space for electric (shareable) cars. Arup is providing multi-disciplinary engineering services, including building services engineering, fire, acoustics and building physics consulting. Haut is being built in Amstelkwartier, a new district on the Amstel that includes about 4,000 homes, shops and businesses. So far, approximately 1,000 homes have been completed and the first school has been opened. The construction of the new city park Somer Lust aan de Amstel has also been finished.
