Public Architecture is an organization with a simple goal: to address public interest through architecture and solve problems of human interaction within the built environment. The San Francisco based non-profit was established in 2002 and in its past ten years it has served as a forum for public discourse, education and advocacy for the design of public spaces and amenities. In 2005 it launched its 1% program, a now nationally recognized portfolio of pro-bono work by architects and firms ready to donate 1% of their year's billable hours to provide work for nonprofit organizations requesting a variety of services that strengthen their architectural identity and community impact. To date, there are 1100 firms registered with the 1% program.
