De Havilland’s house? (5)

I believe the answer is:

villa

I'm a little stuck... Click here to teach me more about this clue!

'de havilland's house?' is the definition.
I can't judge whether this definition defines the answer.

'de havilland's house?' is the wordplay.
'house?' indicates a hidden word (I've seen 'houses' mean this (part of the clue houses the answer)).
'VILLA' can be found hidden inside 'de havilland'.

Can you help me to learn more?

(Other definitions for villa that I've seen before include "Large country house" , "Country residence" , "Aston ..., English Premier League club" , "Ancient Roman's country house" , "Classical country house" .)

I've seen this clue in the Evening Standard.
