A company called Apis Cor has 3D printed a (tiny) house in 24 hours for $10,000, which comes out to about $275/m2.
Reconstructing Buckingham Palace at 77,000 m2 this way would cost only about $21 million. According to a 2010 estimate in The Guardian: "you could build a new energy-efficient replica of the palace for a knock-down £320m", which translates to $552 million.
So: 3D printing the palace would save over a HALF BILLION DOLLARS! Muahahaha (pinkies up!).

I wonder if you could make a bunch of these in close proximity and link them together to make a larger house. And I'm certain you can make them in a variety of shapes, or make part, then move the printer, and make more, to get an overall larger structure. This is how much they made in a day. Give them a week and I'm sure they can build something far more substantial.

You could probably even coordinate multiple adjacent arms working simultaneously so that the walls all went up at the same speed and there would be no "intersection issues" where the support arm printing the base of section 2 needs to pass through the space already occupied by the upper portions of section 1.
