First & Main

Portland, Oregon

Committed to pioneering sustainable development, the owners of First & Main set an ambitious goal: to create the region’s first LEED Platinum speculative office building. This vision shaped a high-performance design featuring a glass curtain wall, multiple roof terraces, and integrated rainwater harvesting, alongside resource-efficient mechanical, electrical, and plumbing systems—ultimately achieving 42% greater water efficiency than LEED’s baseline for domestic use.

To promote alternative transportation, the building incorporates a dedicated bicycle storage facility, showers, and lockers, seamlessly integrated within 20,000 square feet of ground-floor retail space.

Originally designed to achieve LEED Gold, the project evolved mid-design to meet LEED Platinum standards. Through strategic adaptations, the team successfully elevated sustainability performance with minimal additional cost, reinforcing First & Main’s status as a benchmark for environmentally conscious urban office design.
