This week, supertall skyscraper proposals for Manhattan and an orbiting asteroid were unveiled
This week saw the reveal of a Manhattan tower by Zaha Hadid Architects for the family of Donald Trump's son-in-law and a proposal to suspend the world's tallest skyscraper from an asteroid.
The plans for 666 Fifth Avenue released by Kushner Companies involve replacing a 1950s office building and adding 40 floors above its previous height – bringing it within the bracket of a supertall skyscraper, between 300 and 600 metres.
