Tishman Speyer announced the sale of 400 Castro Street, a 100 percent leased, class A office building in downtown Mountain View, Calif.

Tishman Speyer sold 400 Castro to Spear Street Capital for $121.5 million, or $876 per square foot. The firm developed the 138,000-square-foot property in 2002 and immediately leased the office space to Fenwick & West, which has remained a tenant in the building.

Centrally located with access to highways and Caltrain, 400 Castro features efficient floorplates, expansive roof decks, underground parking and views of the San Francisco Bay and coastal mountains. The property is in downtown Mountain View, surrounded by restaurants and retail, with Cascal restaurant, Peet’s Coffee and Sweetgreen on site.

Tishman Speyer was represented by Eastdil Secured.
