Tall timber buildings are on the rise. Design teams around the world are taking advantage of ever-evolving mass timber technologies, resulting in taller and taller structures. Building off our recent article exploring the future of high-rise buildings, we’re taking a deeper dive into new emerging timber technologies and the advantages of building taller with wood. This tutorial explores how to make tall timber structures a reality. …This year, the International Code Council (ICC) announced approval of 14 code changes as part of the 2021 International Building Code (IBC) that will allow mass timber structures of up to 18 stories.
