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!).

It seems the cost is less than 10 000 US$ for the actual 3D printing of concrete:
Foundation - 277 US$
Walls - 1624 US$
It totals at 1901 US$. I wonder if that's concrete + machine rent or just concrete.
Anyway. What is missing is what the roof is made of. Is that concrete too? or some other material?
I'll suppose melted Mars dust and 3D-printing will probably be the thing to use for Musk to do the habitat "over there". That way it can be completed before arrival and use materials on site.
