The A to Z of building a new home... F

 Form follows Function is the principle associated with modernist architecture and commercial design in the 20th Century. The idea is that the shape of a object or building can be based upon its intended purpose or function.Louis Sullivan's phrase ''form (ever) follows function'' became a huge battle-cry of Modernist architects after the 1930's. Louis wrote an article in 1986 '' The Tall Office Building Artistically Considered'' in which he wrote the following passage  “It is the pervading law of all things organic and inorganic, of all things physical and metaphysical, of all things human and all things superhuman, of all true manifestations of the head, of the heart, of the soul, that the life is recognizable in its expression, that form ever follows function. This is the law.”However, not all architects agreed with Louis. While working under Sullivan, Frank Lloyd Wright challenged Sullivan's maxim " form follows function?" and further stated that it had been mis-understood and he firmly believed how " Form and Function should be one, joined in a spiritual union". Despite having slightly contradictory views, Wright credits Sullivan as the primary influence of his career. Facade is a foreign loan word from the French façade, which means "frontage" or "face". In architecture, the facade of a building is often the most important aspect from a design standpoint, as it sets the tone for the rest of the building. Especially from the engineering perspective of a building. The facade is also of great importance due to its impact on energy efficiency. Facade engineering is the art and science of resolving aesthetic, environmental and structural issues to achieve the effective enclosure of buildings. Facadism refers to an architectural and construction practice, where the facade of a building is designed or constructed separately from the rest of a building. Often it refers to the practice where only the facade of a building is preserved with new buildings erected around or behind it. There can be both aesthetic and historical reasons for preserving building facades for building. Facadism can be the response to the interiors of a building becoming  unusable, such as being damaged by fire. The Practice is sometimes used by property developers seeking to re-develop a site whilst presuming the memory of cultural buildings of historical or aesthetic interest.
