'balconied' ultimately originates from Italian, specifically the word 'balcone', where the root 'balco-' meant 'beam' or 'scaffold'.

'balconied' developed from Italian 'balcone' which was borrowed into English in the mid 16th century as 'balcony'; the adjective (or participial) form 'balconied' was later formed in English by adding the suffix '-ed'.

Initially it referred to a projecting platform or scaffold ('balcone'); over time the word came to mean the fixed architectural feature 'balcony', and adjectivally 'balconied' came to mean 'having balconies'.
