Desire to have gables face grass (5)
I believe the answer is:
greed
'desire' is the definition.
(I know that greed is a type of desire)
'gables face grass' is the wordplay.
'face' says to take the initial letters.
'grass' becomes 'reed' (type of grass plant).
The initial letter of 'gables' is 'g'.
'g'+'reed'='GREED'
'to have' acts as a link.
(Other definitions for greed that I've seen before include "Rapacity" , "Covetousness" , "Circuit" , "Immoderate desire" , "Insatiability" .)
