Retention and adaptation of our existing built environment through conversion of buildings, sites or precincts from one use to another can achieve robust, cost effective and sustainable outcomes and imbue such projects with spirit and ambience of place derived from their heritage. Through design strategies that lie between the extremes of demolition or turning a building into a museum, adaptive reuse can extend the history of a site, and by maintaining and interpreting heritage fabric, make both old and new available to new generations. In a range of commercial and residential projects, AJA has been able to demonstrate how such adaptive reuse can also add value through place-making or heritage-led regeneration strategy for a wider area.
