Concrete Block Foundation - Advantages and Disadvantages

Generally laid out in the same pattern as brick, concrete blocks are viewed as cold and utilitarian. Concrete is not easily covered and is difficult to visually enhance. Some people stucco the blocks to hide the ugliness. Others simply paint the blocks and leave them exposed for people to see.
