San Francisco, CA

Union House, 1515 Union Street

Scope/Solutions

The new seven-story building at 1515 Union Street brings forty-one condominiums to northern San Francisco. Residents experience sweeping vistas of the city or the bay from their homes through floor-to-ceiling windows and enjoy views of the Golden Gate Bridge from the rooftop amenity deck. The building steps back to create private balconies and scale the street-facing facade to blend in with the low-rise surroundings. SGH consulted on the building enclosure design for the project.

SGH consulted on the design of below-grade waterproofing, podium deck and planter waterproofing, exterior wall cladding, and roofing. Highlights of our work include:

  • Helped select roofing, waterproofing, window and wall cladding systems to meet the project team’s design vision and performance expectations
  • Reviewed the building enclosure design, identified opportunities to improve performance, and evaluated substitutions
  • Developed details to integrate the building enclosure systems and the many exterior wall systems, including glazed aluminum-framed window walls and storefronts, precast concrete panel, slat rain screen systems, terrace and entrance doors, and formed metal panels
  • Performed below-grade waterproofing warranty inspections
  • Witnessed field performance testing of cladding and fenestrations, and flood testing of amenity roofing and terrace waterproofing systems
  • Provided construction-phase services, including reviewing contractor submittals, providing isometric sketches and cladding models to help the installers, observing ongoing construction, and helping address field conditions
