ONE of the largest estates in Silicon Valley is currently looking to fill five open spaces.

Known as the Start-up Castle, the estate is inhabited by a group of Stanford-affiliated tech workers and researchers who have been using it as a joint group home and workspace.

The impressive property boasts impressive living and work spaces, 100-seat theatre, bar, ballroom and full gym.

If this sounds appealing and you have $US1000 a month for a shared room or $US1750 for a private room, you may just be in with a shot.

That is, of course, if you meet the strict requirements detailed in the SUpost advertisement of the rooms.

“We’re building a community of excellence in one of the most impressive estates in Silicon Valley,” the post reads.

“We believe that the right people in a place like this can make for a great environment and geometric scaling of success for everybody.”

To fit the mould required to join the community of excellence, applicants must have a top-class degree job, exercise at least 15 hours in a week, commute by car less than 20 per cent of the time and like petting dogs.

“These seem to be the common threads among ourselves, and the most successful and trustworthy people we’ve lived with before,” the post reads.

In addition to describing the attributes looked favourably upon, the listing includes a much longer collection of negative traits that are deal breakers, such as:

• Watching more than four hours of TV per week;

• Having more than one tattoo;

• Posting on social media more than three times per week;

• Wearing make-up more than twice a week;

• Driving a vehicle given to you by your parents;

• Using marijuana more than twice a year;

• Having been prescribed anything by a psychiatrist more than once.

A resident of the mansion, only known as John, said the rules were aimed at weeding out people who were too self-obsessed.

“We could just say that we want smart, nice and low-maintenance people … but I think everyone would say that,” he told Fusion.

“We had to be a lot more specific.”
