Bio-Block: Carbon Sequestering Modular Unit is an ongoing design research project that reimagines CMU construction. As a bio-based, reusable, do-it-yourself modular building system, CSMU is composed of load-bearing plywood blocks with plant-based insulation cores.

We began this project by researching carbon-storing insulation materials such as wood fiber, straw, hemp, and seagrass. It has since expanded into a broader exploration of dry assembly, sashimono-inspired interlocking wood joinery, and accessible construction methods.

Bio-Block translates the familiar logic of masonry into a lightweight system that can be stacked, taken apart, and reused. Current prototypes include CMU-scaled uninsulated blocks designed for hands-on public events, where participants can experiment with building walls, seating, platforms, and temporary spatial installations.

In its current iteration, Bio-Block functions as an evolving research platform for low-carbon housing construction, DIY assembly, and open-source building systems. Our long-term goal is to develop a shared catalog of drawings, fabrication files, assembly guides, and material studies open to the public for use, study, critique, and further development.
