Abstract

This study discusses the phenomenon of Building Additions and identifies forces of Attraction and Rejection between the Original and the Addition. It deals with the value and legitimacy of multi-layered objects through the following questions:

  • Can additions become integral parts of the original object, worthy of protection and preservation?
  • Should additions be removed in order to expose the object's originality and authenticity?

The study deals with past and current perceptions of new additions to historic buildings - a major issue due to the importance given to the values ​​of Originality and Authenticity in the conservation discussions during the 20th century. It reviews changing attitudes towards additions to historic buildings from the 19th century to present day, in the classic writings of E. Viollet-le-Duc, John Ruskin and William Morris, Alois Riegel, Cesare Brandi and Paul Philippot, as well more current writers such as Aldo Rossi and Stewart Brand.  

The study also examines the potential relevance of the principles and approaches outlined by the various Preservation Charters (Documentation, Minimum Intervention, Respect for original materials, Reversibility, Compatibility, Distinction between old and new, etc.) for the design and evaluation of additions, preexisting and new. Although multi-layered historical objects are occasionally mentioned in Preservation discourse, these principles were not originally aimed to building additions, and few discussions focus on the legitimacy of new additions to historical buildings.

The Research identifies the "Combined Objects" composed of the original object and its additions. It goes on to define the forces of Attraction and Rejection within these objects, and examines the process of consolidation and integration which the Additions and the Original object undergo to become whole.

Two types of integration process are identified: One is a cyclical process, starting from a 'Basic Object', changing into a 'Conglomerate', into an 'Integral object' and back to a 'Basic object'. The second is a linear process, resulting in a combined object which nonetheless maintains a difference between the Original and its Addition.

 The role of Time and the Human Perception are discussed as major factors in this process of integration.

The contribution of this research is ins analysis of the Combined Object's characteristics, and in the quantitative and qualitative tools it suggests for assessing its capability for change and coherence. The research concludes that architectural objects are non-fixed objects, which can grow, change, integrate and fuse in order to meet the needs of time.
