Won over by husband in high civic building (4,4)

I believe the answer is:

town hall

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

'civic building' is the definition.
(I know that civic building can be written as town hall)

'won over by husband in high' is the wordplay.
'won over by' becomes 'own' (I can't justify this - if you can you should believe this answer much more).
'husband' becomes 'h'.
'in' indicates putting letters inside.
'high' becomes 'tall' (associated in meaning).
'own'+'h'='ownh'
'ownh' put inside 'tall' is 'TOWN HALL'.

Can you help me to learn more?

(Other definitions for town hall that I've seen before include "Main administrative building" , "Municipal HQ" , "Local government HQ" , "Building for offices of urban government" , "Local headquarters" .)
