Elevating SJH: Our Partners
Elevating St. Joseph’s Hall would not be possible without Plant Construction and Jensen Architects, who were responsible for the construction and design of 601 Dolores, our 19,500 square foot, state-of- the-art middle school building.

Since 1947, Plant Construction has produced a heritage of accomplishment, a tradition of excellence and a reputation for dependability. The company was founded by brothers Tom, Buck, and Dave Plant and its first offices were located at 1168 Battery Street in what used to be the produce district of San Francisco, now known as Levi’s Plaza. Their first job began a long history of tackling complex projects with the conversion of an old wooden barge into a duck-hunting lodge. The barge had been sunk and, without insurance, there was little hope of recovering it. Plant Brothers persevered and salvaged the vessel by digging tunnels in the mud at low tide and hand-sawing off the pilings on which the barge was impaled. These rough beginnings formed the foundation for what would become the Plant Construction Company that exists today.
Since the company’s founding, Plant Construction has developed conversions of historic industrial and warehouse buildings into high-end office and residential spaces. This set the company on a growth path that was bolstered by San Francisco’s new requirement that conversions include seismic upgrading. Northern California’s unique economy fueled hotel, retail, and restaurant construction, and Plant developed deep expertise in these areas and grew operations beyond the Bay Area and into other states for national brands with multiple physical locations. The company maintained steady growth across management and skilled trades, and continued to build a reputation for precision and excellence on complicated and challenging projects.
Building 601 Dolores
Originally constructed as a church, the building at 601 Dolores Street in San Francisco formerly served as a soup kitchen and was most recently converted to a high-end, single-family residence before being sold to Children’s Day School. Renovation of the property for use as a Middle School consisted of removal of most of the interior floors and walls to make way for accessibility and seismic upgrades. The full interior build-out of the ground level, second level, mezzanine level, and upper tower levels provides classroom and administrative spaces for educational use. In this design, the south side of the roof level is also built out as inviting seating and garden space. Accessibility to all levels was made possible through the installation of an elevator and three communicating stairs. Plant performed upgrades to the building exterior, utility connections, entries, and surrounding sidewalks. The project also included specialty functions (theatrical, assembly, science, arts, lounges, etc.), salvage and re-use of existing finishes, and all-new mechanical, electrical, plumbing, and fire protection systems.
