A 12-storey building proposed for Portland’s Pearl District has received the go-ahead from planners, paving the way for it to become the USA’s first high-rise wooden structure.
The Framework Building, designed by Lever Architecture to be built from mass timber, was approved for construction by the State of Oregon and the City of Portland this week.
Buildings with load-bearing wooden structures over 85 feet (30 metres) tall were previously not permitted by US codes.
Therefore the proposed timber frame, which includes a combination of engineered woods like cross-laminated timber (CLT) and glue-laminated timber (Glulam), had to undergo rigorous testing to meet seismic, fire and acoustic requirements.
