Dwarfed house, not surprisingly (8)
I believe the answer is:
outshone
'dwarfed' is the definition.
(I've seen this before)
'house not surprisingly' is the wordplay.
'surprisingly' is an anagram indicator (a surprising ordering of the letters).
'house'+'not'='housenot'
'housenot' with letters rearranged gives 'OUTSHONE'.
(Other definitions for outshone that I've seen before include "Made better or brighter impression than" , "Dwarfed" .)
