Because of increased secularization and decreased parish revenues, obsolete churches are being sold. Adaptive re-use could preserve the cultural heritage these buildings represent, while having many further benefits. Decision modelling helps view these problems with every actor and their viewpoints in context and in relation with one another and the goal function. The case of the [church name] in [village name] was modelled in the original situation as well as an extended case, where more choice options were added and the new position of the Diocese was considered. Then more situations and aspects from various cases were modelled. In this way the fitness for use of a decision model for choices to be made in adaptive re-use of obsolete churches was proven. The use of decision modelling in adaptive re-use of obsolete churches might in the future lead to more successful outcomes.
