Architecture is the activity of designing and constructing buildings and other physical structures, primarily to provide socially purposeful shelter. A wider definition often includes the design of the total built environment, from the macro level of how a building integrates with its surrounding man made landscape to the micro level of architectural or construction details and, sometimes, furniture.
Architects have as their primary object providing for the spatial and shelter needs of people in groups of some kind (families, schools, churches, businesses, etc.) by the creative organisation of materials and components in a land- or city-scape, dealing with mass, space, form, volume, texture, structure, light, shadow, materials, program, and pragmatic elements such as cost, construction limitations and technology, to achieve an end which is functional, economical, practical and often with artistic and aesthetic aspects. This distinguishes architecture from engineering design, which has as its primary object the creative manipulation of materials and forms using mathematical and scientific principles.
Separate from the design process, architecture is also experienced through the senses, which therefore gives rise to aural, visual, olfactory, and tactile architecture. As people move through a space, architecture is experienced as a time sequence. Even though our culture considers architecture to be a visual experience, the other senses play a role in how we experience both natural and built environments. Attitudes towards the senses depend on culture. The design process and the sensory experience of a space are distinctly separate views, each with its own language and assumptions.
Architectural works are perceived as cultural and political symbols and works of art. Historical civilizations are often known primarily through their architectural achievements. Such buildings as the pyramids of Egypt and the Roman Colosseum are cultural symbols, and are an important link in public consciousness, even when scholars have discovered much about a past civilization through other means. Cities, regions and cultures continue to identify themselves with (and are known by) their architectural monuments.
Sculpture is three-dimensional artwork created by shaping hard or plastic material, commonly stone (either rock or marble), metal, or wood. Some sculptures are created directly by carving; others are assembled, built up and fired, welded, molded, or cast. Because sculpture involves the use of materials that can be moulded or modulated, it is considered one of the plastic arts. The majority of public art is sculpture. Many sculptures together in a garden setting may be referred to as a sculpture garden.
