'commonly-built' originates from the combination of 'common' and 'built', where 'common' meant 'usual or typical' and 'built' referred to 'physical structure'.

'commonly-built' evolved from the Middle English word 'comun' and the Old English 'byldan', eventually forming the modern English term 'commonly-built'.

Initially, it meant 'having a typical structure', and this meaning has largely remained the same in modern usage.
