At an unnamed house in the Harrison West neighborhood of Columbus, an ingenious use of blocks is evident to the world, if anyone in the world pauses to take a look while passing by. The house made a retaining wall with a mix of block pavers. Taking a quick look, these were a few of the styles I spied: Townsend Block ZO, Nelsonville Block, 20th Century, Athens Block, Portsmouth Block, Harris and Hocking Block. If I looked a little harder, I am sure I would have seen a few more.
