ECONOMICS AND TRADITION The life of a building is not necessarily a function of how long it stands up before it falls down, it may depend upon positive or negative decisions about maintenance. A decision may be made to demolish a building which is unsuitable for other than structural reasons. High rise flats provide a particularly striking examples of this. It has also been known for multi-storey buildings to be demolished for purely economic reasons before construction was complete. This example was seen in the early 1980's in Wanchai, Hong Kong when a 25 storey block of flats, which had been built up as 21 storeys was demolished before its construction was complete.
