A new skyscraper in San Francisco tops 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 designer Orlando Diaz-Azcuy and architectural firm Heller Manus Architects set out to make the building the epitome of luxury. 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.
