Architecture is the design and construction of an object, mainly buildings. Architecture designs can differ from time to time. Architects can also convey a deeper meaning through their architectures for a certain purpose of the building.
EQ2) What are the essential considerations when one architects a building/structure?
One would need to consider the types of materials used to build the building. For example, the French used high quality materials imported directly from Southern France to construct the replica of the Notre Dame. The materials must be strong enough to withstand the weight of the occupants and objects in the building, and the design of the building must be relevant to the purpose of the building, but at the same time, stable.
