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!).

One 3D printer to do the rough work, one to do the finer details. Carpenters not needed as they may dovetail together with minor sanding and adhesive application.
As a tradesperson, I am glad my area of work is in troubleshooting, rather than construction...that may remain relevant for some time more.
