Overarching panel plans red revolt (8)

I believe the answer is:

spandrel

'overarching panel' is the definition.
(architectural term)

'plans red revolt' is the wordplay.
'revolt' is an anagram indicator.
'plans'+'red'='plansred'
'plansred' is an anagram of 'SPANDREL'.

(Another definition for spandrel that I've seen is " Triangular space between the top of an arch and its rectangular frame".)

I've seen this clue in The Times.
