The Mountain View Campus and Amenity Strategy

The newly leased campus underwent a comprehensive two-year redevelopment led by TMG Partners to meet the evolving demands of post-pandemic tech environments. Beyond modernized office interiors, the site features a two-acre amenity zone designed to foster employee collaboration and wellness. High-end features include:

Multiple diverse dining options on-site.

Professional-grade tennis and sand volleyball courts.

Expansive outdoor common areas and integrated green spaces. According to TMG President Ben Kochalski, the focus on "amenity-rich" environments is a direct response to the flight-to-quality trend currently stabilizing the Silicon Valley office sector.
