The term 'style of a building' can be summed up by the word 'ARCHITECTURE'. ARCHITECTURE is the art and science of designing and constructing buildings. It involves the planning, design, and construction of structures such as houses, office buildings, churches, and other structures. Architects use a variety of materials, techniques, and styles to create aesthetically pleasing and functional buildings. They must consider the needs of the people who will use the building, the environment in which it will be built, and the cost of construction.
