Carbon 12 – Portland, Oregon

Completed between 2016 and 2018, Carbon 12 is a landmark mass timber project in Portland, Oregon. At 29 meters in height and with a gross building volume of 3,000 m², it is recognized as the tallest mass timber building in the United States.

The design by PATH Architecture combined a steel core with glulam framing supplied by Mercer International, with engineering support from KPFF Consulting Engineers. To meet the structural demands of a multi-story residential building, RICON S connectors were chosen for their strength and installation efficiency, ensuring secure beam-to-beam and beam-to-column joints throughout the structure.

Key Highlights:

Connector technology: RICON S connectors provided reliable strength for tall timber applications.
Construction method: Hybrid system with a steel core and glulam structural elements.
Design features: Exposed timber interiors with natural light and modern residential finishes.
Scale: 29 meters tall, approx. 3,000 m² gross building volume.
Use case: Multi-family residential housing that set a precedent for tall wood construction in North America.

Carbon 12 demonstrates how RICON S connectors enable safe, efficient, and innovative tall timber projects, blending sustainability with modern urban design.
