Architecture has transformed from a complex creative process of integrating diverse functions, structural systems, myriad services and utilities, inter-related spaces and exterior-interior visual connections into a game of appliqué where one cuts and pastes decorations and ornament onto four sides of dull boxes.

Building having Exterior Metal finish with diffused Lighting Techniques | Architecture

The building in the picture above has a facade that is completely covered with sheets of perforated metal and acryllic  sheets. Since they are working with metal, they are welding materials together and they are using these Welding Helmets. Diffused lighting technique has been used to illuminate the facade of the building. The use of diffused lighting has been used in an innovative manner.

The building has to be made look visually pleasing. Ornamentation without function is otiose. But the trend has changed which has changed the definition of Ornamentation.
