   For instance, the cluttered, homely design of, say, the Burrow, is in itself, a masterly piece of design; […] and, crucially, it can also be translated into commercial products, such as an area of the wizarding world theme park, a training level in a video-game, and a LEGO playset that currently retails at over £60.

2. A unitary structure for children to play on, typically including a slide, and often swings, ropes to climb on, and other things found as separate structures at public playgrounds.
