Hangars, greenhouses and barns
This material category bundles the buildings that are dismantled and partly or wholly sold as "building kits". Although the types of structures that fall into this category differ in terms of age, material and appearance, what they have in common is that their connections are easily reversible, their design is standardised (to a certain extent), the volume-to-material ratio is often impressive, and their reuse is generally cheaper than buying a new structure. The different practices are very region-specific, but relatively standard within certain economic activities (such as agriculture, horticulture, industry, etc.).
