The following are typical stone bonds frequently found in walls or used for faces on buildings. Ashlar Pattern (at right) An Ashlar pattern is usually done with squared (quarry cut) stone. Unlike brick, the height and width of the stone will vary. Coursed Ashlar lays stone of equal height but unequal length in regular courses. Each course may use stones of a different height, but all stones in one course have about the same height. Random Ashlar Pattern (below) This is a type of ashlar construction where the building blocks are laid apparently at random, but usually are placed in a definite pattern which is repeated again and again. There are no regular courses of one height. Stones of different heights and lengths are laid next to each other. Random Ashlar Pattern. Stone is Ct. Blue.
