"Do it yourself" ("DIY") is the practice of undertaking the construction, modification, or repair of objects or spaces independently, without the assistance of qualified professionals or certified experts. Academic research has described DIY as a behavior in which "individuals use raw and semi-raw materials and parts to produce, transform, or reconstruct material possessions, including those drawn from the natural environment ". DIY behavior can be driven by various motivations previously categorized as market-based, and identity-enhancing.
