Fine example of something that's laid: a brick (4,3)
I believe the answer is:
good egg
'a brick' is the definition.
(I've seen this before)
'fine example of something that's laid' is the wordplay.
I cannot really see how this works, but
'fine' could be 'good' (I've seen this before) and 'good' is found within the answer.
'example' could be 'eg' (short for 'exempli gratia', 'for example' in Latin) and 'eg' is found in the answer.
A single letter 'g' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for good egg that I've seen before include "A brick!" , "Trustworthy person?" , "Sound fellow (unlike the curate's?)" , "that shouldn't float!" , "Sport" .)
