Renovation, rehabilitation and other types of alterations to existing buildings should allow for understanding of the built environment and its place in our built heritage through minimal interventions that remain distinguishable from the original structure. Construction should respect historic fabric and seek to protect it.
Minimal interventions in existing structures allow future students of history to understand and appreciate the original historic building and Gesamkunstwerk, or unity of craft, as well as the patina. Interventions that have kept it viable should remain distinguishable from the original structure.
