瑞典斯德哥尔摩Norra Tornen住宅

Narra Tornen项目采用预制混凝土板，这项技术使得工程可以在5度以下——这种温度下现浇混凝土就无法流动了——的环境中继续进行。此外，预制混凝土还大幅度削减了建造开支，使得墙地比接近1的设计方案成为了可能。而在一般的项目中，0.5的墙地比所需的造价就会让开发商却步。由此节省下来的经费可以被用来创造多朝向、大开窗的独特户型，这对于瑞典这个一年中一半时间都缺乏阳光照射的国家来说尤为珍贵。矗立于二战之前建造的住宅群之中，Norra Tornen项目为斯德哥尔摩带来了新的生活方式，人们可以在高密度的生活中享受属于自己的户外空间。 Concrete at Norra Tornen comes in the form of prefabricated panels – a construction technique that allows work on the building site to continue even below the five-degree Celsius limit which prohibits in situ concrete pouring. Prefabrication also significantly reduced construction costs. This way a design with a wall-to-floor ratio close to 1 – most developers would be discouraged by a 0.5 ratio – was suddenly not an unthinkable proposition. The investment could be channeled in creating apartments with unique layouts, multiple orientations and extra square meters of windows – a precious asset in a country with scarce daylight for half of the year. In a city center with a housing stock largely built before the Second World War, Norra Tornen introduces a new way of living which brings together density with the possibility to enjoy outdoor space (Stockholm ranks fourth among the cities with the highest air quality in the European Union).
