After 10 years in Northwest Austin, Google has completed its move downtown.

The tech giant unveiled on Tuesday its 300,000-square-foot space in the newly opened 500 W. Second St. office tower. More than 450 Google employees will work at the facility once two additional floors open next year.

The new office features open workspaces, terraces overlooking Austin, a stairwell modeled after the city's greenbelts, a recycled waterfall feature and an airstream trailer that serves food.

Mayor Steve Adler announced a $250,000 Google.org grant to Workforce Solutions at the grand opening ceremony. The grant will make 10 new employer pipelines for local workers, help expand skills-training programs to serve more low-income students and start 20 data-sharing agreements encompassing education and workforce programs.

“A major part of our effort to make Austin more affordable is lifting people out of poverty and into good paying jobs,” Adler said. "Today’s grant from Google.org to Workforce Solutions is a big contribution to our mission of lifting 10,000 Austinites out of poverty and into good jobs over the next five years. This is yet another example of why it is important for companies like Google, which shares our community's values, continue to call Austin home.”
