Complementary architecture

Complementary architecture is a movement in contemporary architecture promoting architectural . Indispensable features of complementary architecture include sustainability, altruism, contextualism, endemism and continuity of specific regional design language. Complementary architecture occurs at the intersection of local pattern and design languages. A pattern language represents a set of more or less formalised rules of human interaction with built forms, resulting from practical solutions developed over time according to local culture and natural conditions. A design language in architecture is a set of geometrical (formal) and material standards used in buildings and other man-made structures, traditionally arising from local materials and their physical properties. Complementary architecture interprets the Vitruvian triad for contemporary use, mapping durability (firmitas) against aspects of broader sustainability, utility (utilitas) against altruism and service to society, and individual beauty (venustas) against harmony with broader context, regional identity and spirit of place. Historically, building environments were produced in a continuous, evolutionary fashion rather than as singular revolutionary events. Complementary architecture involves systematic analysis of traditional techniques in the context of vibrant urban environments, aiming to rediscover sustainable, layered, nuanced, contextual and environmentally appropriate solutions for the present time. Practically all traditional vernacular and formal architecture produced prior to the 20th century is complementary architecture due to inherent material and cultural constraints, as are many works inspired by some contemporary movements such as contextual architecture, indigenous architecture, organic architecture or new urbanism. Complementary architecture methodology is especially useful where contemporary development penetrates compact historical urban fabric. Complementary design pays respect to its architectural context while carefully introducing contemporary design elements.
