 The retention of only the two street facades of the 1890s Colonial Mutual Building on Martin Place in 1976 to allow an office tower behind is probably the earliest example of facadism in Australia, and set a precedent for the following decade.The most notorious was the treatment of the 1850s North British Hotel in Loftus Street in 1983, where the bland office building facade rose straight up from the retained facade, and had been given the bonus floors on the basis of the preservation.In 2018, a new development on a larger site saw its complete demolition, noting that it was not officially heritage protected.
