Bishop in old farm building (6)

Ross

I believe the answer is:

stable

'farm building' is the definition.
(I know that stable is a type of farm building)

'bishop in old' is the wordplay.
'bishop' becomes 'B' (abbreviation for bishop in chess).
'in' means one lot of letters goes inside another.
'old' becomes 'stale' (synonyms).
'b' placed within 'stale' is 'STABLE'.

(Other definitions for stable that I've seen before include "Outhouse for horses" , "Jesus was born in one" , "Well balanced" , "firmly tied on?" , "far from bats?" .)
