MENLO PARK, CALIF.: The official name of the newest building at Facebook’s headquarters, MPK 21, may evoke computer jargon, but the gleaming new offices are anything but mundane. They offer a village where employees can gather, create and relax.

Employees have started moving into the company’s new offices in a long, airy building, which features a “main street” meandering down the middle, along with office “neighborhoods” that have sprouted off to the side. Workers can stroll on a rooftop, gather in “town squares” featuring redwood trees, or pause in a terraced area called “The Bowl” that is like a botanical garden.

Frank Gehry, the world-famous architect who previously designed Facebook’s adjacent MPK 20 building, also created the new MPK 21 offices. The building is designed to reflect the social networking company’s culture and its stated mission of bringing communities together.

Facebook, like many other technology companies, is determined to create inviting work areas that can help to lure skilled recruits and keep existing employees happy.

“There is a sense of energy and connection in this building, and you see people collaborating,” said John Tenanes, Facebook’s vice president of global facilities and real estate.

The new offices also include an events center with 2,000 seats where Facebook Chief Executive Mark Zuckerberg intends to hold weekly question-and-answer sessions, Tenanes said.

The building can accommodate 2,900 employees. It totals 525,000 square feet and occupies 24 acres. It stands 79 feet tall at its highest point and stretches 1,376 feet — more than four football fields long.

Facebook and Gehry see MPK 21 as building on the knowledge gained from designing the nearby MPK 20, which features a rooftop of park lands, gardens and trees.

“We were getting lessons in the Facebook culture,” Gehry said in a Facebook video about the new offices. “And we are making a new kind of architecture within that culture.”

The design allows employees to flow through the structure, gathering in large and small groups in the open offices. The building also has cafes, restaurants and at least one pop-up store.

Each office neighborhood in MPK 21 was designed to accommodate about 150 workstations.

“You see lots of gathering places, little neighborhoods, sort of spontaneous nooks where people can get together without reserving a conference room,” said Janelle Gale, Facebook’s vice president of human resources. “You see walking paths where people do meetings. We want places that give you head-down quiet space, but also spaces where there is more energy that provides you connections to colleagues.”
