These days the growth of society is accelerating and there are many new technical and cultural problems to be considered. Buildings must therefore be in a position to respond to these rapidly evolving new environments. Buildings should no longer be constructed planned and developed for a single program only, but should take into account a variety of choices over centuries. One way to do that is through the adaptability of buildings; if correctly constructed, buildings can be re-programmed and re-inhabited without the possibility of needless deconstruction.
