Policy 17 Changes to buildings and fabric
Physical alterations to significant fabric should be limited to works that do not diminish the cultural heritage values of West Block and the Dugout.
West Block has long history of adaptation and alteration in response to the requirements of its varied occupants.  The first significant alterations occurred within a decade of the building's completion, and the most recent major works were completed in the early 1980s.  Further physical and functional change at the building is anticipated.  From a heritage perspective this can reasonably be contemplated, providing that the works do not diminish the cultural heritage significance of the place overall.
The Dugout is a physically unprepossessing structure that has been modified, extended and repurposed on two occasions since its construction in 1942.  Alterations to the building to reveal its original form should be encouraged, supported by in-situ interpretation to communicate the nature of the building's historical significance.

General principles
The future use of West Block is likely to require physical change in the form of alterations, internal demolition and new works (note, new development is addressed at Policy 18).  Where this occurs, the overriding objectives are firstly to retain and conserve significant fabric, and secondly to plan and undertake works in a manner that is sensitive to the valued form and presentation of significant fabric and elements.  All alternative approaches should be investigated before significant fabric and elements are removed
The extent of change at West Block since 1927 is such that reconstruction to an earlier or original form would be neither viable nor appropriate – the building's evolved form should be understood as part of its historical significance.  There is, however, potential for that process of evolution to continue, subject to the recommendations of this HMP.  Where actions are proposed that reveal or uncover original or early features of the building, these actions can be contemplated in the context of this evolutionary process.  Any reinstatement works should be delivered accurately, based on the comprehensive documentary record for the site.
General principles are that the building's external form and fabric should be retained; there is very limited potential for permanent additions physically attached to the building.  There is greater potential for change to the interior, which has been the subject of multiple configurations over time (internal subdivision) and includes limited evidence of original/early details and finishes.  More detailed guidance on future change at West Block is included at Table 7, exterior and Table 8, interior.  Guidance on future
