Simple Solutions for a Limited Budget: Designing affordable housing in the heart of San Francisco

An award-winning affordable housing project located in a vibrant urban setting, the Curran House required cost-effective structural design solutions. The nine-story, 85,000-sf low-income development features 67 apartments, including a mix of studio, one-bedroom, two-bedroom and three-bedroom units. The structural system consists of reinforced, post-tensioned concrete slabs supported by reinforced concrete shearwalls with a reinforced concrete mat foundation.

Project Highlights

  • Due to the plethora of nearby public transit connections, the unit required no parking, saving several million in construction costs on the project.
  • The space saved by not building parking was used to include a rooftop community garden, additional units, common space and ground-level retail.
  • A professionally landscaped ground-floor courtyard provides a play space for residents’ children.
