Mason on Mariposa

Mixed-Use Community in Potrero Hill

Nearly a million people live in San Francisco. High prices and limited schools makes living in the city a challenge for many young families, and the need for multi-family housing, perpetual. Mason on Mariposa brings one of the first new multi-family living developments to the Potrero Hill neighborhood. Our team proudly served as Executive Architect for the development that provides 299 new homes and retail across 3.5 acres. A publicly accessible greenway from Mariposa Street to the 18th Street retail corridor and nearby elementary school make the three-building development an ideal home base. The three residential buildings were an undertaking of complex design, engineering, and construction. As Executive Architect, we planned and coordinated every aspect of the architecture, from initial permitting to final completion. Working alongside our client and three separate design architect teams, we brought hundreds of new, desperately needed homes to the city.

Architecture Story

Public Space on Potrero

Mason on Mariposa required immense collaboration between our client, the city, the general contractor, all the engineers, and three outside Design Architect teams. As Executive Architect, we were responsible for the entire project—leading communication and leveraging each teams' strengths to hit key project milestones. The development sits in the heart of the family-friendly Potrero Hill neighborhood. In addition to 299 new homes, the design creates a new east-west, public green passageway that strengthens the development’s connection to the community and the nearby elementary school and retail area on 18th Street. At-grade entrances allow families to easily navigate a stroller or kids on bikes to the open courtyards. The courtyards are ideal gathering and event spaces for the residents to host parties, let their kids play, and connect to one another. With a mid-rise profile nestled into the hill, Mason on Mariposa keeps views of the Bay and city skyline open. Our attention to every detail also ensured Mason on Mariposa is as energy efficient as possible. We worked to reduce each building’s energy load, like a curtain wall system that combines glass and solar technology. The best accessibility experts, enclosure specialists, spec writers, and interior designers from Ankrom Moisan worked together to coordinate the complex project. Targeting LEED Gold, the complex is one of the first to bring new multi-family living space to the area. The three mixed-use residential and retail buildings offer hundreds of people homes in a family-friendly neighborhood—connected to schools, jobs, and panoramic views of the San Francisco skyline.
