Tower Road, its origin before road works (7)
I believe the answer is:
mirador
'tower' is the definition.
(I've seen this before)
'road its origin before road works' is the wordplay.
'road' becomes 'M'.
'origin' suggests taking the first letters.
'before' becomes 'r' (I can't justify this - if you can you should give a lot more credence to this answer).
'works' is an anagram indicator (letters worked into a new form).
The first letter of 'its' is 'i'.
'road' with letters rearranged gives 'ador'.
'm'+'i'+'r'+'ador'='MIRADOR'
(Another definition for mirador that I've seen is " tower".)
