HV Engineering is proud to have provided the mechanical and plumbing engineering for Heartwood, a pioneering mass timber workforce housing development in Seattle.
As the first Type IV-C mass timber building in North America, this eight-story project sets a new standard for sustainable urban housing. Located in Capitol Hill, Heartwood delivers 126 affordable homes for middle-income residents while significantly reducing embodied carbon through the use of CLT and glulam construction.
Projects like this represent the future of our industry — combining thoughtful design, innovative construction methods, and a commitment to sustainability. We’re honored to have contributed to a project that not only advances mass timber construction, but also helps address the growing need for housing in our communities.
Heartwood was recently featured on America ByDesign (Season 5, Episode 6). Take a look at the project starting at the 25:26 mark:
