A-55

**A55 Wohnen am Bifang** in Olten, completed from 2017 to 2018, involved the extensive renovation and conversion of an existing mixed-use building. Under the architectural direction of **Skyline Development AG / rd2b limited**, 43 modern rental apartments were created, featuring flexible layouts and appealing terrace units on the upper floors. Valued at CHF 17 million, the project included a comprehensive energy upgrade, hazardous materials remediation, and seismic reinforcement, while preserving adaptable commercial spaces on the ground and terrace levels. With its focus on providing affordable urban housing and revitalizing the Bifang neighborhood, **A55** stands as a prime example of contemporary urban development.
