Church under pressure to accommodate gold in hall (5)
I believe the answer is:
porch
'hall' is the definition.
'church under pressure to accommodate gold' is the wordplay.
'church' becomes 'ch' (common abbreviation).
'under' says to put letters next to each other.
'pressure' becomes 'p' (abbreviation).
'to accommodate' indicates putting letters inside.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'ch' after 'p' is 'pch'.
'pch' enclosing 'or' is 'PORCH'.
'in' is the link.
(Other definitions for porch that I've seen before include "Covered entrance to house" , "Veranda" , "Protection over a doorway" , "Sheltered entrance" , "Roofed entrance to house" .)
