Mass Timber, Up Close: Inside Kalamazoo College's New Residence Hall

Some of the best conversations in construction happen on site, surrounded by the work itself. Dan Gelder, project superintendent for Owen-Ames-Kimball Co., experienced that recently at Kalamazoo College's new residence hall. Joined by Susan Lindemann, Associate Vice President for Facilities Management, Dan got a firsthand look at a project that has been a long time coming.

"We are putting up our first new residence hall in 60 years here at Kalamazoo College," Susan said, "and we really think it's a special build."

Why Mass Timber?

For the Kalamazoo College team, mass timber was not just a structural choice. It was a values statement.

"Mass timber is really biophilic," Susan explained. "Studies have shown that introducing natural materials into a building space actually reduces anxiety and stress and improves productivity. We really want that for our students."

Mass timber products like cross-laminated timber (CLT) and glulam beams are manufactured by bonding layers of wood under pressure, creating structural elements strong enough to replace steel and concrete. The material is lighter, faster to install, and stores carbon rather than emitting it, making it one of the more compelling low-carbon options in construction today. All of the timber on this project is southern pine, sourced from the southeastern United States and manufactured in Alabama.

Sustainability at the Core

Mass timber is one piece of a broader sustainability story at Kalamazoo College. The four-story residence hall also incorporates geothermal heating and cooling, passive energy strategies, and high-performance building systems alongside student lounges, a community kitchen, a marketplace, study spaces, and other shared amenities. Construction is on track for completion in Summer 2027.

O-A-K recently welcomed students from Michigan State University's Mass Timber program to the jobsite, along with supplier SmartLam North America, for a tour as Quality Buildings LLC begins timber installation at the east tower and lobby. For the next generation of builders, there is no better classroom than the jobsite itself.
