Queenslander architecture is a modern term for a type of residential housing, widespread in Queensland, Australia. It is also found in the northern parts of the adjacent state of New South Wales, and shares many traits with architecture in other states of Australia, but is distinct and unique. The form of the typical Queenslander-style residence distinguishes Brisbane's suburbs from other capital cities. The Queenslander is considered Australia's most iconic architectural style.

A cornerstone is the first stone set in the construction of a masonry foundation. All other stones will be set in reference to this stone, thus determining the position of the entire structure.
