SAN JOSE — Google has swallowed three north San Jose properties in a major expansion of its areas of interest in the Bay Area, buying three industrial buildings in a business park being developed by Trammell Crow.

Mountain View-based Google paid $117.3 million on Tuesday for the buildings, Santa Clara County property records show.

The buildings are part of the Midpoint@237 business park. Together, the buildings, which are all new, total 563,000 square feet.

This transaction marks Google’s biggest foray into north San Jose. The business park is located just north of State Route 237 and is near the Alviso community.

The buildings, according to Santa Clara County property records, are all located on Disk Drive in north San Jose. The addresses are 5079, 5087 and 5093.

The 5079 Disk Drive building is 233,000 square feet, the 5093 Disk Drive property is 168,000 square feet and the 5087 Disk Drive building is 162,000 square feet.

All the buildings are long structures of an industrial nature. Each has multiple large doors that could be used for deliveries of supplies.

At least one other major tech company recently made its first major push into north San Jose.

Microsoft in September paid $73.2 million for 65 acres of empty farmland along Highway 237 between Alviso and Milpitas on the western banks of Coyote Creek. The software and cloud services giant is eyeing a data center on the vacant property, which is also zoned for office buildings.

Separate from its ventures in north San Jose, Google is also busy buying properties in downtown San Jose, in a development partnership with Trammell Crow.

The search behemoth’s downtown endeavors could lead to the construction of 6 million to 8 million square feet of office space, enough room to accommodate 15,000 to 20,000 Google employees.

Google wants to build a transit-oriented community in downtown San Jose since the development would be near the Diridon train station, which is emerging as a hub for an array of transit lines.
