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.

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
