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. To better understand the term building compare the list of nonbuilding structures.
Land
Land, sometimes referred to as dry land, is the solid surface of Earth that is not permanently covered by water. The vast majority of human activity throughout history has occurred in land areas that support agriculture, habitat, and various natural resources. Some life forms (including terrestrial plants and terrestrial animals) have developed from predecessor species that lived in bodies of water.
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

Generally speaking, no young tree is allowed to stand on copyhold land.
Edward Coke, 3rd Rep. 15; reported in James William Norton-Kyshe, Dictionary of Legal Quotations (1904), p. 147. Hence the maxim, that "the oak scorns to grow except on free land."
Land
The equal right of all men to the use of land is as clear as their equal right to breathe the air — it is a right proclaimed by the fact of their existence. For we cannot suppose that some men have a right to be in this world, and others no right.
Henry George, Progress and Poverty (1879), Book VII, Ch. 1.
