Alden B. Dow utilized this Unit Block system in many of his early designs including his own home and studio. In addition to structural support of exterior walls, the versatility of the blocks extended to interior spaces as well – table bases, level changes, division of spaces, columns – to create artistic, visual interest. He even positioned the Unit Blocks like steppingstones across the pond, farther and farther apart as they escape from the disciplined grid of the building.

These sets of blocks come in two sizes, small (5 blocks – 4 rhomboid and 1 corner) and large (17 blocks – 14 rhomboid and 3 corner) bags, and are made of maple; hand-crafted at the Alden B. Dow Home and Studio.
