Freestanding structures are found all over the world, and have been marvelled at not only for their height, but also for their beauty. The tallest building in the world is a freestanding structure.
"Freestanding" is defined by Merriam-Webster as "standing alone or on its own foundation free of support or attachment," as in a freestanding wall.
Freestanding vs. Non-Freestanding
If a structure is not freestanding, then it is a supported structure. Non-freestanding structures include those such as cable-supported, air-supported, frame-supported, and tensile structures.
