This $665 million skyscraper in San Francisco will be the tallest residential building on the West Coast

A new skyscraper in San Francisco topped off this month, rising 70 stories over the city's financial center. Upon completion in 2017, 181 Fremont will be the tallest residential tower west of the Mississippi River - and possibly the most lavish and exclusive.

Renowned architect Orlando Diaz-Azcuy set out to make the building opulent and luxurious. The $665 million tower spares no expense, from the gold-plated door handles to the hovering walls.

Business Insider recently toured a model unit located up the street. Take a look.
