Yeon Building Renovation

Built in 1911, the neo-classical building was commissioned by John Baptiste Yeon, a self-made lumber baron, and designed by prominent San Francisco architect firm Reid & Reid. At 15 stories it was one of Portland’s first high-rise buildings, and held the distinction of being the tallest building in Portland for 16 years after it was built.

After 100 years, the Yeon is ready for its second act.  The 135,000 sq ft renovation accomplishes an LEED EB/OM Silver Certification, as a downtown hub for the next generation of companies who value character, quality, and innovative green design.

The renovation work included the implementation of new sustainable systems and significant cosmetic improvements including new storefront façade, efficiency upgrades to mechanical and electrical systems, and more.

Lochsa Engineering provided the design and detailing of exterior metal stud framing system at ground level for support of GFRC panels, light gauge framing shop drawings, calculations package, and GFRC design and support calculations for submittal.
