Formerly seen as a menial architectural task, adaptive reuse has come into its own. It is no longer a secret, and certainly no longer a novel idea, that the archi-tecture of adaptive reuse is, in terms of architectural creativity, beauty and impor-tance, in no way inferior to designing and building a brand-new building (Hauke and Werner 2011).Architecture incorporating existing structures has been experiencing an enormous boom and an increase in prestige for some time, and as claimed in this chapter, has become an architectural genre of its own. Preservation has tradition-ally been the driving factor for maintaining historic structures. Until recently, the reuse of existing buildings almost always meant dealing with historically listed buildings. These days adaptive reuse of older structures is not only in vogue but makes up a major part of the current construction industry’s business. Surpris-ingly, such projects are to a large degree no longer using only historical listed buildings. What has changed?
