Concrete masonry offers many benefits for residential construction: solid construction, low maintenance, fire safety, and thermal mass that contributes to energy efficiency. The houses on these pages show just how handsome and varied residential concrete masonry can be. They stand on sites ranging from urban to rural, representing regions all across the country. All were custom-designed by architects, some as their own residences. Each house uses architectural block as its major building material and each makes a strong architectural statement.
