Description

    Vision and Concept

     

  • Rosenhøj, a social housing area in Viby Syd, Aarhus, underwent a comprehensive transformation focused on openness, identity, and community.
  • New housing typologies were introduced, with the middle sections of existing blocks demolished to create visual connections and open the neighborhood to its surroundings.
  • Diverse designs and materials were used for facade renovation, pairing blocks with matching facades and creating shared courtyards to foster smaller, identity-rich communities.
  • The neighborhood was divided into 11 small communities, each with housing blocks, terraced houses, and shared garden spaces.
  • A former parking lot was transformed into a shared park for community use.
  •  

    Transformation Journey

     

  • Originally built in the 1970s, Rosenhøj faced social challenges and developed a negative reputation over the years.
  • The transformation, carried out from 2014-2017, brought economic, environmental, and social improvements.
  • The project improved resident trust and relationships, as reflected in positive social housing reports.
  •  

    Security, Neighbour Relations & Desirability

     

  • Trust and Security: Resident surveys show a 37% increase in trust among neighbors from 2008 to 2017.
  • Decrease in Insecurity: The number of people feeling insecure dropped by half, from 23% to 11.6% in the same period.
  • Increased Demand: Desirability for homes in Rosenhøj increased, as shown by substantial waiting lists.
  •  

    Energy Optimization and Futureproofing

     

  • The transformation included futureproofing measures, such as upgrading building envelopes, replacing ventilation systems, and improving insulation.
  • 85-90% of surplus heat in buildings is reused, resulting in a 50% reduction in total energy consumption.
