A builder’s face? (6)
I believe the answer is:
facade
This might be a double definition.
'a builder's' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'face?' is the second definition.

Can you help me to learn more?
(Other definitions for facade that I've seen before include "Walton's setting of Sitwell's verses" , "Outside of a building" , "External surface" , "Series of notes" , "Front presented" .)
