What is different about architecture now?
In contemporary architecture, the materials often decide the design. There is little decoration. It is simple and uncluttered and often, the supporting pillars and beams are shown. Reinforced concrete and steel allow architects to use fewer columns, beams and thick walls. This means that buildings can now be lighter and taller. Modern buildings often use glass walls, which allow more heat and light inside. The latest trend among architects is to design buildings where the need for heating and lighting is minimized. These are called energy-efficient buildings.
