Foyer, or roller rink? Good question! (via Curbed.com)

In honor of the Zynga-enriched Pincuses, who recently closed on a $16 million Pacific Heights pile described as "very massive, very Old Money," Curbed has an envy-inducing little roundup of swank mansions belonging to wealthy West Coast techies.

Suddenly, the Valley as tech nirvana makes more sense than ever. Not since the Gilded Age has it been possible for even the wealthiest robber barons to lay claim to this much space in Manhattan.

The new home of Mark and Allison Pincus is not merely spacious but just about as historic as you can get out in California, short of moving into a Spanish mission:

The 11,500-square-foot, seven-bed, seven-bath spread was built in 1907 for the Newhall family, who owned it for 105 years before passing the title along to Pincus in exchange for his many millions. Hopefully, they weren't paid in stock.

Zynga zinger! Of course, as Curbed points out, Mrs. Pincus is the cofounder of decor-frenzy-inspiring ecommerce site One Kings Lane, so really it would've been unimaginable for them to live in anything less.

We also noticed that Mr. Mark Zuckerberg, though settling for a mere 5,000 square feet, somehow managed to find a home in Silicon Valley that looks almost unbelievably Westchester-like:

Also, there is a croquet lawn. You're not getting that in the West Village, no matter how idyllic your townhouse.

Meanwhile, Jack Dorsey inhabits a cliffside mansion with a retractable roof and a view of the Golden Gate Bridge, while Larry Page apparently just keeps buying up surrounding properties.

Perhaps the jokes on both coasts, though: Mark Cuban lives in a 24,000-square-foot Dallas monstrosity that, frankly, might as well be Wayne Manor. Then again, even the Vanderbilts had to go as far as Asheville, North Carolina to build the Biltmore.
