Houses of Parliament and Big Ben
This is larger than the game allows so you have to mess about a bit to position it. The left side needs to go against a road and if there are any roads under the black bits they will need to be removed and repositioned later. You will also need to add your own decorations as I couldnt outside of the build area.
