The Boyen Fortress: structural analysis of selecting complementary forms of use for a proposed adaptive reuse project.

Extending the life cycle of heritage buildings through their adaptive reuse can ensure their survival and is concordant with the policy of sustainable development. Selecting a new form of use for heritage building adaptive reuse projects is a multidimensional process that can be significantly aided by multi-criteria decision-making approaches. In this paper, the authors have proposed a hybrid form of structural analysis, which is a formulation of a multi-criteria approach to the analysis of complementary forms of use for a complex of historical buildings, to be used during the early planning stages of adaptive reuse projects for heritage building complexes. The approach has been demonstrated on the example of the Boyen Fortress complex in Giżycko, Poland. The outcome of the analysis indicated that the highest share of floor space to be adapted should be dedicated to exhibition spaces, which is justified concerning cultural heritage benefits. This approach can be of significant aid to decision-makers during adaptive reuse project planning phases, thereby facilitating the continued survival of heritage sites. [ABSTRACT FROM AUTHOR]
