Redesign faded green on first couple's home (6,2,4)
I believe the answer is:
garden of eden
'first couple's home' is the definition.
(where Adam and Eve lived)
'redesign faded green on' is the wordplay.
'redesign' indicates an anagram (I've seen 'redesigned' mean this).
'faded'+'green'+'on'='fadedgreenon'
'fadedgreenon' is an anagram of 'GARDEN OF EDEN'.
(Other definitions for garden of eden that I've seen before include "Home of Adam and Eve" , "Idyllic haunt" , "holy plot?" , "Scene in Genesis" , "Pre-lapsarian paradise" .)
