I am curious to know what should be done with 24 Sussex Drive. When Harper was prime minister, he chose to leave it the way it is, despite the fact that it is mouldy, lacks central air conditioning and heating, contains asbestos, and its exterior renovation does not reflect the original architectural style. Oh, and 24 Sussex Drive is among the smallest residences for national heads of government in the G8, so small, visiting dignitaries would rather be entertained in Rideau Hall. The price of renovating 24 Sussex Drive is rising. The most recent estimate was $15 million in October 2015, as compared with $10 million in 2008. Some have suggested to demolish 24 Sussex Drive and replace it with a more modern residence, as the existing house is almost structurally unsound and is a heritage building, albeit one not legally bound.
