345 Middlefield

Menlo Park, CA

Located on a 17-acre former U.S. Geological Survey campus just east of downtown Menlo Park, 345 Middlefield is a proposed mixed-use development that reimagines an underutilized government campus into a connected, community-oriented neighborhood. The plan includes approximately 670 residential units, 740,000 square feet of office space, and neighborhood-serving retail, dining, and childcare, all organized around publicly accessible open space and landscaped grounds.

Designed to support a new generation of living and working in Menlo Park, the project brings together housing, workplaces, and daily amenities in a walkable, integrated environment. Positioned near major transit routes and adjacent to emerging innovation hubs, 345 Middlefield builds on the momentum of nearby developments to create a cohesive and enduring district rooted in connectivity, flexibility, and long-term placemaking.
