Framework is a 12-storey, 44-metre-tall mixed-use structure in Portland, Oregon that is set to become the tallest mass timber building in the United States.
Designed by Lever Architects, the project will include 2900 square metres of offices on levels two to six, and 60 apartments on levels seven through to 11, as well as 69 parking spaces for bikes.
Framework will be constructed mainly from cross-laminated timber (CLT), which is manufactured by compressing and gluing together plywood-like layers of lumber at 90-degree angles.
It is hoped that sustainably harvested wood will encourage mills in Oregon to produce CLT, which can replace steel and concrete in the construction of high-rises.
The use of CLT enables faster and less carbon-intensive methods of construction, while it is hoped that its use will also boost jobs in the timber sector.
Construction work on Framework is due to begin later this year, with completion expected by the winter of 2018.
