Buckingham Palace is apparently in need of some major updates — to the tune of over $455 million.
And most of those updates won't be seen. They include replacing 100 miles of the palace's electrical wiring, 20 miles of heating pipes and 10 miles of hot and cold water pipes.
In the process, workers will have to pull up the equivalent of 3.5 soccer fields' worth of floor boards.
Some of the wiring, piping and other systems are over 60 years old. The palace says the upgrades are necessary to avoid "catastrophic failure leading to fire or flood."
According to the palace, the upgrades will reduce costs and make the palace more energy efficient. The plan also calls for solar panels to be installed on the flat parts of the palace's roof over the next 10 to 15 years.
With inflation taken into account, as well as savings spurred by the improvements, the palace estimates the cost will end up being closer to £222 million pounds, or over $274 million.
The updates will take place in several phases over the next 10 years. The work begins in April 2017.
