The term self-build is essentially compositional, though a likely source of inspiration is the concept of do-it-yourself or DIY, used to refer to home improvement projects undertaken without the help of paid professionals. The terms do-it-yourself and DIY were, in fact, coined in the 1960s by craftsman/TV presenter Barry Bucknell, though it was not until the 1980s that DIY became a markedly popular weekend pastime. It seems that amid growing resources and popularity in the last two decades, DIY has naturally evolved into build-it-yourself or BIY, as people have increasing involvement not merely in the improvement of their own homes, but also in their original design and construction.
