History

Established in 1991.

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.

Since 1991, we have successfully stayed within budget on large scale affordable housing renovations; infused private residences with green materials and passive solar features; and enhanced community centers in support of neighborhood revitalization. OSA places special emphasis on integrity, practicality and quality.
