Architecture is in simple terms, the science of building. In other terms, the definition of architecture is as follows: the practice or art of designing building structures, especially those that are habitable. Besides, architecture may refer to a construction or formation, resulting from any conscious act by an individual. For instance, Notre Dame of France is a beautiful piece of architecture. The Taj Mahal, a notable wonder of the world, is another beautiful architecture that decorates the face of the earth. Architecture involves an effort to come up with a structure for a task, function or purpose. It may refer to the inability of the creative mind and expertise to design and construct, or the actual product of such undertakings.
Buildings are not mere objects. They are products of science, with a combination of artistic techniques human creativity. People who design buildings are architects. They consider and utilize all architectural principles and scientific considerations in order to come up with attractive structures that are secure for human habitation, or use. A good construction or formation of architectural design must be convenient to use and be safe. On the other hand, a poor architectural structure fails to offer convenience, safety, or both. In the case of a building, security and safety are paramount with comfort as a secondary consideration.
In short, there are multiple versions of the definition of architecture. This depends on the field of study, in question. For instance, in computer technology, the definition differs markedly from that of architects. However, as a prospective architect, my definition remains tied around designing and building/construction of structures. That is why my definition remains: architecture is the science of the building or the practice/art of designing and building of structures, especially the habitable ones.
