MASTER PLANNING
At Jackson | Main Architecture, P.S. (JMA), we redefine the boundaries of traditional design studios by leveraging the diverse strengths of our exceptional team. We prioritize the unique needs of our clients and end-users, ensuring that every design is a thoughtful response to their aspirations and requirements. Since 1967, our adaptable approach, combined with a commitment to quality and innovation, has established us as a trusted advisor and esteemed design partner.
From Seattle's 40-foot-extended Great Wheel and Pier 57 restaurants to the immersive Wings Over Washington motion ride and the newest Sasquatch Mountain attraction, JMA's iconic designs have reshaped the city's waterfront landmarks.
SELECTED WORK
AWARD WINNING AND LEED CERTIFIED PROJECTS.
SUSTAINABILITY
Performance is designed in, not added on.
Our LEED-accredited team treats energy, water, and material decisions as core design inputs from day one — not a checklist applied at the end.
Envelope and systems modeled early to reduce operational energy use well beyond code minimums.
Energy performance
Low-flow fixtures, smart irrigation, and stormwater strategies reduce potable water demand on site.
water efficiency
Regional sourcing and off-site fabrication cut material waste and shorten supply chains.
Responsible materials
Ventilation, daylighting, and low-emission finishes designed around occupant health.
