Move over steel and concrete — a pioneering cross-laminated timber (CLT) project that’s set to break ground in Boston could spearhead a greater adoption of mass timber across the country. Local startup Generate Architecture + Technologies has teamed up with progressive developer Placetailor to lead the project — the city’s first-ever CLT Cellular Passive House Demonstration Project — and provide live/work spaces in Lower Roxbury. Developed with the startup’s Model-C system for prefabricated kit-of-parts construction, the building will forgo conventional concrete and steel materials in favor of carbon-sequestering engineered wood products.

Expected to break ground in June of 2020, the CLT Passive House demonstration project will comprise five floors with 14 residential units as well as innovative and affordable co-working spaces for the local community on the ground floor. In addition to introducing low-carbon, mixed-use programming to the neighborhood, the project will be a working prototype for Generate’s Model-C, “a replicable system for housing delivery methods designed to address climate and community.”

The Model-C system is not only designed to function at net-zero carbon levels, but is also Passive House certified and built to the new Boston Department of Neighborhood Development “Zero Emissions Standards,” which were developed with Placetailor. As a result, the demonstration project is expected to have a significantly reduced carbon footprint as compared to traditional construction. The CLT rooftop canopy is also engineered to make it easy to mount solar panels. Modular units, like the bathrooms, can be prefabricated offsite and then plugged into the building to reduce construction time and waste.

Thanks to prefabrication methods and the reduction of interior framing, the Model-C prototype is expected to completed by the end of 2020 and will be available for tours at the Industrial Wood-Based Construction (IWBC) conference in Boston on November 4. Generate is also exploring the possibility of applying the Model-C system to projects that range from six to 18 stories across the U.S.
