Queenslander architecture is a modern term for the vernacular type of architecture of 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 type developed in the 1840s and still constructed today, displays an evolution of local style.
Vernacular architecture is a category of architecture based on local needs, construction materials and reflecting local traditions.
Queenslander buildings are primarily of timber construction and can be low or high-set, one to two stories. They are typically “tripartite” in sectional composition; underfloor (stumps), primary rooms (can be two levels), and roof. All have one or more veranda spaces, a sheltered edge of the building that is typically only part-enclosed and used as another living zone. This consideration for climate is the defining characteristic of the Queenslander type.
The roof is a large and visible presence externally and was traditionally steeply pitched. They are of varied materials including slate and tiles but are most characteristically sheeted with corrugated iron. The iron roofs could withstand torrential rains and be re-used if damaged by cyclonic winds.
The Queenslander, a “type” not a “style”, is defined primarily by architectural characteristics of climate-consideration. (Ref)
