The Sydney Opera House

An Evolving Icon 

Patricia Hale and Susan Macdonald

 

Despite only recently celebrating its 30th birthday, Sydney Opera House is undoubtedly one of the iconic architectural monuments of the twentieth century; it is a symbol of a nation and the most visited place in Australia. It is also Australia's busiest performing arts centre. This paper is the first of two papers outlining the history of Sydney Opera House and the current approach to its management and conservation, examining the framework for the building's care and ongoing adaptation in the face of pressures arising from tourism and changing performance technologies.

The recent re-engagement of architect Jorn Utzon provides opportunities for the evolution of Sydney Opera House to continue in the spirit of the architect's design philosophy. Given that the building was completed by others in 1973, seven years after Utzon's controversial departure, both the identification of the building's heritage significance and well-articulated policies for managing these values are critical. The paper will outline the framework for decision making at Sydney Opera House and introduce examples of how the current approach works in practice.

Conservation Plans and the Development Process

Chris Miele

 

Conservation plans have been promoted in the United Kingdom for more than a decade, but there is to date no research to establish whether they are working as intended. Anecdotal evidence suggests they are not, and the author, who has prepared many plans, argues that the fault lies to some extent with the way the current guidelines are written. These should, he argues, be based on a more complex understanding of the development process, and he illustrates this point by reference to specific plans that he has prepared for different kinds of client.

The Sandford Inventory of Earth Buildings as a Conservation Aid

Margaret Ford, Richard Griffiths and Linda Watson

 

The Sandford Inventory of Earth Buildings is an effective tool for characterizing and identifying earthen buildings in Sandford (Devon) and demonstrates the advantages of using a Geographical Information System (GIS) to integrate and analyse the differing data. A case study on a listed building reveals the problem of identifying cob buildings that have altered facades. The findings from the case studies on two non-listed buildings demonstrate the predictive ability of the inventory methodology to identify previously unidentified cob buildings using the triangular concept of combining documentary architectural and historic information with topographical factors to discover their location. The ability of the methodology employed by the Sandford Inventory to display cartographic, graphic, and photographic material could be used to enhance the list descriptions of cob buildings

The Changing Facade of Magdalen College, Oxford

Reconstructing Long-Term Soiling Patterns from Archival Photographs and Traffic Records

Mary Thornbush and Heather Viles

 

Most studies in the area of stone soiling and decay research focus on relatively short periods, usually less than ten years. This study attempts to consider changes over a century using archival photographs, and to relate them to changes in traffic-related air pollution as recorded in surveys and monitoring data. The facade of Magdalen College is an often-photographed component of Oxford's cultural heritage. Its location adjacent to Magdalen Bridge, which is a major traffic artery into Oxford, makes it vulnerable to traffic-related pollution. Traffic surveys reveal a recent decline in traffic, dating from around the time of the Oxford Transport Strategy, only partly matched by nitrogen dioxide reductions. The photographic records show the facade of Magdalen College to be blackened well before traffic became a serious threat. The study illustrates the problems of the archival record, but also its value in providing some insight into long-term changes in air pollution and the consequences for cultural heritage.

The Holnicote Thatching Project

Bridget Litchfield

 

This paper discusses the thatching works that have been undertaken on the National Trust's Holnicote Estate in West Somerset. Surveys of the estate's thatched properties were undertaken in 1999; these highlighted the need to carry out urgent remedial works on a number of roofs that had been leaking for some years. As a result, a specific project was set up in 2000 that provided a unique opportunity to implement a repair programme aimed at gaining a better understanding of the performance of thatch and thatching techniques. The three-year funded project encompassed the repairs to the roofs, documentary research and investigation of thatching materials and techniques, monitoring the performance of thatching straw, and the production of straw at the Holnicote Estate. Although the thatching project has ended in terms of specific funding, work continues on the estate in terms of repairs, monitoring, and straw production.

Restoring a Bosphorus Yalı

The Elusive Goal of Authenticity

Dorothy Dinsmoor

 

On the Asian shore of the Bosphorus strait in Istanbul, the eighteenth-century Sa'dullah Paşa yalı (waterside summer residence) stands as an instructive example of the successful application of international standards for authenticity in restoration, achieved within a complex set of circumstances. This yalı is one of a diminishing number of wooden shore residences of a specific type built by high Ottoman officials during the 200 years of the empire's decline. Designed expressly as the setting for spectacular festivals meant to impress the sultan and his European guests, these waterside houses occupy a unique place in architectural history. Their conservation is thus a matter for international concern.
