Firm Description

Okamoto Saijo Architecture (OSA) focuses on innovative designs in housing, ecological design and neighborhood planning. OSA has recently completed several neighborhood housing developments and several custom passive solar residences.

OSA is a small design office where each project is directly managed by one of the partners on a daily basis — from conceptual design to construction administration — guaranteeing immediate access to the firm's experienced leaders. Founded in 1991, both Paul Okamoto and Eric Saijo are licensed California architects and they each have over twenty-five years of architectural experience. Both partners have expertise with concrete, steel and wood-framed construction. They are also familiar with the city planning approval and landmark processes and all phases of architectural services from programming to construction administration. OSA is registered with the San Francisco Human Rights Commission as a LBE.

OSA regularly works, both as architects and as public advocates, with non-profit community and environmental organizations to enhance the quality of life in the Bay Area. Paul and Eric have also played an active role in non-profit organizations such as the Asian Pacific Environmental Network, East Palo Alto Historical & Agricultural Society, Greenbelt Alliance, Urban Ecology and the Urban Habitat Program. Paul has been Chair of the Advisory Council for the Bay Area Air Quality Management District (1998-99), and an appointed member of the Commission on the Environment for the City of San Francisco (1993-99), where he worked on the first resource-efficient ordinance for the City. In recognition of his civic leadership in urban development issues, Paul was awarded a Loeb Fellowship at the Graduate School of Design at Harvard University, which he completed in June 2001.


Design Approach
Okamoto Saijo Architecture has developed a combination of skills that balances innovative and functional design with project administration. Our design approach is based on integrating building design, budget, cost control, project administration and local construction practices into architectural projects. We have demonstrated the ability to achieve project goals and budgets for our clients, and to help them plan for the complexities of their projects. In addition, we are skilled in "green" building" design and community participation processes.

A value-added design skill is our experience in "green building". We have designed, researched and implemented energy-efficient building systems, passive and active solar designs, and recycled, nontoxic and resourceful materials. We have also specified a diverse range of "green" materials in our projects, such as PISE earth walls, cellulose insulation, certified lumber, ACQ-Preserve pressure-treated lumber, cement fiber siding, low VOC paints and stains, wheat and straw boards panels and cabinets, and recycled glass countertops.

An important part of our design process is the Pre-Design Report, a conceptual design tool that helps define the overall scope of work and construction budget before beginning the formal architectural design process. This tool provides our clients with a preliminary overview of their projects which helps establish project goals and preliminary budgets. Throughout all of our projects, we work closely with our clients. Our facilitation of the design process allows us to zero in on a strong design direction and provides clearer communication and closer oversight of the construction budget. Our solid experience in planning and project management, coupled with our unique green design vision, provides the basis for realizing innovative architectural designs and well-organized projects.
