Station F restaurant hall

When it comes to hobbies, some tech billionaires are off trying to buy land in New Zealand to prepare for Doomsday.

Not Xavier Niel, who is one of France’s richest men and worth £7 billion, according to Forbes

Niel is spending his millions turning an old railway depot in Paris into what he claims is the world’s biggest startup campus.

It’s the first space of its kind in the city, housing up to 1,000 international startups under one roof.

The building is based in Paris’ 13th arrondissement, an area mostly known for warehouses and Chinese restaurants, local VCs told Business Insider.

Station F is still a building site, but the first startups are due to move in during the first week of July.

Here’s a look at the unfinished site:

This is the Halle Freyssinet, an abandoned railway building from the 1920s.

It was built in 1927 by Eugene Freyssinet, a pioneering French civil engineer.

The Halle Freyssinet fell into disrepair, but telecoms billionaire Xavier Niel bought the building in 2013 for €70 million (£60 million).
