and research buildings. Located in what’s deemed to be a development darling, the Peery Park district, the new project is roughly a one-mile drive from the Caltrain station in downtown Sunnyvale.

The corporate neighbors for the new campus consist of tech titans and numerous upstarts. Among them: Apple, LinkedIn, Microsoft, Riverbed, Alibaba.com, Proofpoint, Synopsys, Walmart. com, Twitter, and 23&Me.

In April, Sunnyvale Owner, an affiliate controlled

by Harvest and Invesco, paid $165.5 million for the empty land and the three research building parcels at and near the corner of Maude and Pastorio, according to Santa Clara County property records that were filed April 24.

The Harvest and Invesco group paid $120.5 million for the three buildings, which have addresses of 810 and 870 W. Maude Ave. and 474 Potrero Ave., and $45 million for the vacant land, which is at the southeast corner of West Maude and North Pastoria, the county documents showed.
