Google's Silicon Valley HQ has a new 31,000-square-foot amenity-packed floor with looks inspired by salt mining - see inside

The new amenity space is over 31,000 square feet at Google's Mountain View, California headquarters.

The design is inspired by salt production, and also based on the history and character of the South Bay.

Lighting fixtures and the ceiling are meant to evoke salt's molecular shape, according to the designers.

The "Tech Talk" auditorium is a place for presentations and guest speakers.

Ceiling elements imitate the natural shape of San Francisco's salt ponds and also absorb sound in the space.

Even seating configurations are inspired by visual features of salt and salt production.

The amenity area has three cafes, each with seating.

The office subtly references changes to the Bay Area's landscape as materials change from green to wood to metal.

The office is partially open, but wooden partitions and glass walls break up the space and allow for private conversations.

Partitions also allow natural light to flow between sections of the office.

Nearly half of the space is occupied by the fitness center, equipped with weights and machines.

The salt mine theme even extends into the fitness center, which has a map of the Bay Area on one wall, and seating areas that are shaped like salt outcrops.

The locker room is sleek and modern.

Finally, Google employees can hit the refresh bar to cool down after a workout.
