Functionalismin architecture, is the principle that architects should design a building based on thepurpose of that building.The place of functionalism in building can be traced back to the Vitruvian triad, where'utilitas' (variously translated as 'commodity', 'convenience', or 'utility') stands alongside'venustas' (beauty) and'firmitas' (firmness)as one of three classic goals of architecture.In the early years of the 20th century, Chicago architect Louis Sullivan popularized thephrase“form ever follows function”to capture his belief that a building's size, massing, spatial grammar and othercharacteristics should be driven solely by the function of the building. The implication is that ifthe functional aspects are satisfied, architectural beauty would naturally and necessarilyfollow.en.wikipedia.org
