Commonly used for the end-of-life phase of a building and understood as the result of physical and aesthetical deterioration. More explicitly, it is the growing divergence between steadily rising expectations due to technological advances and changes in demand on one side, and declining performance on the other. The reasons can include behavioural and physical aspects like the degradation or fatigue of materials over time, poor design choices or insufficient maintenance. The maltreatment of a building such as misuse, overload or a change in functions are behavioural factors that might lead to obsolescence. Physical impacts of nearby construction, rising standards and government regulations like taxation amplify obsolescence of the surroundings or building locations. Social deprivation processes, criminality, availability and aesthetics on the other hand, are external behavioural factors. Obsolescence is irregular, it often differs from building to building and its internal and external factors are diverse and influenced by a multitude of factors. [1,2]
