'modern-built' originates from the combination of 'modern' and 'built', where 'modern' refers to the present or recent times, and 'built' is the past participle of 'build', meaning 'constructed'.

'modern' evolved from the Latin word 'modernus', and 'built' is derived from the Old English 'byldan'.

Initially, 'modern' referred to 'current or recent', and 'built' meant 'constructed'. Together, they describe something constructed in a contemporary style.
