Who we are.

"Johnson Architecture & Planning" was founded by Stevan Johnson in 1987. Today, now Johnson Oaklief Architecture & Planning, Steve Johnson and team continue to build a legacy of exceptional buildings. 

Johnson Oaklief Architecture & Planning began with and continues to focus the firm's architectural practice on urban design and development, the design and planning of mixed-use and mixed-income residential buildings, high technology, educational, institutional and community facilities.

A Cornell University alumni from New York, Steve started and became the sole proprietor of JOA&P after fourteen years in the role of executive director for the Environmental Works/Community Design Center. Since then, Steve has been a part of many local advisory boards, including the Seattle Design Commission and was selected as one of the team leaders for the Seattle waterfront design charrette. Steve has direct experience as a project architect and planner on an exceptional variety of public and privately developed projects. He has received national recognition for his architectural work on landmark structures and for the design of affordable housing. Planning projects include predevelopment analysis of major urban mixed-use projects, to site assessments for public facilities. Major projects include the corporate headquarters for Amgen Corporation and for the Washington State Community College system. 

After almost twenty years working with Steve and the JOA&P team (and upon the 30th anniversary of the firm in 2017), Jeff Oaklief is named principal of the firm. Jeff has a tremendous amount of experience working projects of all shapes and sizes throughout the Northwest. His understanding of the intricate phasing, scheduling, and demanding technical requirements are a great asset to our team and clients. 

The team at JOA&P continues to uphold a core philosophy of architectural practice in finding the most imaginative, appropriate and cost-effective solutions that meet the highest standards of design and amenity. Above all, the firm approaches each project as an opportunity to provide a legacy of good buildings in the community and to create noteworthy design that fully meets client’s expectations. 

The firm has a history of success maintaining strong relationships with local officials and agencies in the region. Participation on many public commissions has provided lasting connections in working with local communities and stakeholders, as well as enhancing awareness of the complex regulatory environment. 

The team also has a significant background completing LEED certified projects maintaining a scope of green building awareness and sustainable practices at every level possible.
