|The Darwin D. Martin House (from Ausgefuhrte Bauten und Entwurfe von Frank Lloyd Wright (Berlin, 1910)|
In relation to authenticity, the reconstruction of archaeological remains or historic buildings or districts is justifiable only in exceptional circumstances. Reconstruction is acceptable only on the basis of complete and detailed documentation and to no extent on conjecture.
As for Integrity here is some of the language:
Integrity is a measure of the wholeness and intactness of the natural and/or cultural heritage and its attributes. Examining the conditions of integrity, therefore requires assessing the extent to which the property:
a) includes all elements necessary to express its outstanding universal value;
b) is of adequate size to ensure the complete representation of the features and processes which convey the property’s significance;
c) suffers from adverse effects of development and/or neglect.
This should be presented in a statement of integrity.
the aesthetic qualities of the property.
The issue with the Martin House lies with the demolition in the 1960s of the pergola, conservatory, and carriage house, and their eventual reconstruction using new materials and painstaking research based upon Wright's drawings, photographs, artifacts and extensive letters.
The omission of the Martin House remains a sore point in some quarters, particularly in the light of the inclusion on the World Heritage List nomination of the Marin County Civic Center which was built entirely posthumously between 1959 and 1964. Perhaps, one day, the Martin House will be nominated as a World Heritage Site on its own.
