This person's appealing on record for revered architect (7)
I believe the answer is:
imhotep
'revered architect' is the definition.
(ancient Egyptian architect)
'this person's appealing on record' is the wordplay.
'this person's' becomes 'im' (this person means the crossword setter themselves).
'appealing' becomes 'hot'.
'on' says to put letters next to each other.
'record' becomes 'ep'.
'im'+'hot'+'ep'='IMHOTEP'
'for' is the link.
(Other definitions for imhotep that I've seen before include "Ancient Egyptian" , "Egyptian physician, architect; him poet (anag.)" .)
