House Portuguese military guards (4)

I believe the answer is:

semi

'house' is the definition.
(short for semi-detached)

'portuguese military guards' is the wordplay.
'guards' indicates a hidden word.
'SEMI' is hidden in the letters of 'portuguese military'.

(Other definitions for semi that I've seen before include "home perhaps" , "Not quite the biggest tie" , "accommodation" , "Residence" , "match, the last but one?" .)

I've seen this clue in The Sun.
