Adaptive reuse refers to the process of reusing an existing building for a purpose other than which it was originally built or designed for. It is also known as recycling and conversion. Adaptive reuse is an effective strategy for optimizing the operational and commercial performance of built assets. Adaptive reuse of buildings can be an attractive alternative to new construction in terms of sustainability and a circular economy. It has prevented thousands of buildings' demolition and has allowed them to become critical components of urban regeneration. Not every old building can qualify for adaptive reuse. Architects, developers, builders and entrepreneurs who wish to become involved in rejuvenating and reconstructing a building must first make sure that the finished product will serve the need of the market, that it will be completely useful for its new purpose, and that it will be competitively priced. Definition Adaptive Reuse is defined as the aesthetic process that adapts buildings for new uses while retaining their historic features. Using an adaptive reuse model can prolong a building's life, from cradle-to-grave, by retaining all or most of the building system, including the structure, the shell and even the interior materials. This type of revitalization is not restricted to buildings of historic significance and can be a strategy adopted in case of obsolete buildings. Some urban planners see adaptive reuse as an effective way of reducing urban sprawl and environmental impact. Revitalizing the existing built fabric by finding a new use or purpose for obsolete buildings can be a wonderful resource to a community by "keeping neighborhoods occupied and vital". According to Yung and Chan, "adaptive reuse is a new kind of maintainable rebirth of city, as it covers the building’s lifetime and evades destruction waste, encourages recycles of the embodied dynamism and also delivers substantial social and economic profits to the world". Benefits and Challenges of Adaptive Reuse Benefits: Typically categorised under economic, social, cultural and historical, and environmental benefits. The most significant benefits of adaptive reuse of existing buildings include increased economic opportunities, urban regeneration, preserved cultural and historical heritage values, reduced landfill demolition waste, increased energy efficiency, extended building usefulness, and cost-effectiveness, enhanced property value, improved life quality, reduced carbon emissions, and lesser energy consumption. Challenges: Typically categorised under building regulatory requirements and governance, financial, management, and complexities and uncertainties challenges. The most significant challenges of adaptive reuse of existing buildings include structural integrity
