The CityCronan redevelopment project renovated a mixed-use property in Central Stockholm and was intended to be an environmental model by limiting the building’s impacts throughout its service life.

Project Introduction
CityCronan is a mixed-use property in Central Stockholm that has undergone extensive redevelopment work. The original building was constructed in 1974 and was in urgent need of renovation. CityCronan is now a modern development comprising of offices, shops, restaurants and apartments.

Skanska Sweden carried out the US$ 130 million project for Skanska Commercial Development Nordic (CDN) between 2000 and 2003. The project involved merging two buildings, constructing new facades, strengthening the entire structure with steel frames and improving the street environment around the CityCronan development. Sections of the CityCronan development were also vertically extended by 2 and 4 floors, on a design and build contract. The redeveloped property has a total floor area of 53,000 m², including 30,000 m² of office space and 6,000 m² designated for retail outlets. 44 new apartments were created on the expanded upper floors, and an inner courtyard with a glazed roof has been constructed.

A Swedish construction industry magazine awarded the CityCronan project the Best Redevelopment prize in 2004 for the way in which the modernisation was carried out and for revitalising the surrounding neighbourhood. The project also won the Skanska Best Renovation and Upgrade project award in 2003. The CityCronan redevelopment was a model environmental project, which aimed to limit the building’s impacts throughout its entire service life and to contribute toward the development of more resource efficient construction projects in the future. A lifecycle analysis was used to evaluate the building’s components throughout their entire service life, from initial redevelopment, operation and future renovations to final demolition.
