Building
A building, or edifice, is a structure with a roof and walls standing more or less permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, and aesthetic reasons.

System
A system is a regularly interacting or interdependent group of items forming an integrated whole. Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning.
Building
To be a man is to be responsible: to be ashamed of miseries you did not cause; to be proud of your comrades' victories; to be aware, when setting one stone, that you are building a world.
Antoine de Saint Exupéry Wind, Sand and Stars,' (1939), p. 93
