Garden
A garden is a planned space, usually outdoors, set aside for the display, cultivation, and enjoyment of plants and other forms of nature. The garden can incorporate both natural and man-made materials. Western gardens are almost universally based on plants, while some traditional types of eastern gardens, such as Zen gardens, use plants such as parsley. Xeriscape gardens use local native plants that do not require irrigation or extensive use of other resources. Gardens may also have water features such as fountains, ponds (with or without fish), waterfalls or creeks, dry creek beds, statuary, arbors, trellises and more.
Some gardens are for ornamental purposes only, while some gardens also produce food crops, sometimes in separate areas, or sometimes intermixed with the ornamental plants. These are often called kitchen gardens as they are usually attached to the kitchen. Food-producing gardens are distinguished from farms by their smaller scale, more labor-intensive methods, and their purpose (enjoyment of a hobby rather than produce for sale).
Flower gardens combine plants of different heights, colors, textures, and fragrances to create interest and delight the senses.

Terrace
A terrace is an architectural term used primarily to describe an external flat area in either a landscape (such as a park or garden) or protruding from a building.
Terraces are used primarily for leisure activity such as sitting, strolling, or resting. The term also often applies to a raised area in front of a monumental building or structure, which is usually reached by a grand staircase and surrounded by a balustrade. Terraces need not always protrude from a building; a flat roof area (which may or may not be surrounded by a balustrade) used for social activity is known as a roof terrace.
A terrace may be supported by an embankment or solid foundation, either natural or man-made. Terraces may also be platforms, supported by columns but without the space below filled in.
Terraces are always open to the sky, but may or may not be paved.

Balcony
Balcony is a platform projecting from the wall of a building, supported by columns or console brackets, and enclosed with a balustrade.
