Resumen
Worldwide population is rapidly growing economically and politically. Hence, countries have challenges of conserving its heritage properties. However, the rapid development is emerging, ignoring the existing architectural relic on the assets. Thereby fading away historical value and loss of asset?s identity. Lack of optimum reuse decision-making and less application of the available models contributed to such phenomenon, particularly in developing countries. Consequently, this study aimed at appraising the models adopted in developed countries by reviewing 9 Journal articles from year 1999 to 2017. As a result, Europe and USA were found to have the practice of conserving their built assets.
