We collected over 40 projects, including mixed-use destinations, confidential client offices, LEED-certified buildings, and mass timber-built headquarters.
We’re breaking down the submissions into several individual articles to highlight what makes each project special. Because these were all completed in the last 18 months or are currently under construction, these office building and office-to-res projects showcase the latest the market has to offer in terms of amenities, products, and construction techniques.
