'conventionally-constructed' originates from the words 'convention' and 'construct', where 'convention' meant 'a way in which something is usually done' and 'construct' meant 'to build or form by putting together parts'.

'convention' and 'construct' were combined to form the modern English term 'conventionally-constructed'.

Initially, it referred to any structure built using traditional methods, and this meaning has largely remained the same in modern usage.
