A house in Austria, Haus Hohlen, has had an entirely new exterior built around it. The original building is now part of the new house's interior. The house is located on a hill above Dornbirn in Austria and was built back in 1961. However, renovation and extension efforts were deemed necessary in 2012.
The building's existing stonework was preserved -- however, the rest of it was stripped naked. The remaining original structure was then enclosed by a completely new envelope of an exterior. The interior portion is still recognizable although many features have been changed.
Windows were added to take advantage of the house's surrounding views. A number of eco-friendly features were also added to reduce Haus Hohlen's heat-related energy needs to just 45 kilowatt hours per square meter a year.
