Rough site being redeveloped? That's good (9)
I believe the answer is:
righteous
'good' is the definition.
(similar in meaning)
'rough site being redeveloped?' is the wordplay.
'being redeveloped?' indicates anagramming the letters (I've seen 'redeveloped' mean this).
'rough'+'site'='roughsite'
'roughsite' anagrammed gives 'RIGHTEOUS'.
'that's' acts as a link.
(Other definitions for righteous that I've seen before include "Showing virtue" , "Good!" , "Just, upright" , "Morally justified" , "Virtuous, free from sin or guilt" .)
