Soldier returns from centre overlooking residence way up north (5)

I believe the answer is:

igloo

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

'residence way up north' is the definition.
I can't judge whether this defines the answer.

'soldier returns from centre overlooking' is the wordplay.
'soldier' becomes 'gi' (government issue or general issue).
'returns' is a reversal indicator.
'from' means one lot of letters go next to another.
'centre' says to take the centre.
The centre of 'overlooking' is 'loo'.
'gi' back-to-front is 'ig'.
'ig'+'loo'='IGLOO'

Can you help me to learn more?

(Other definitions for igloo that I've seen before include "Ice-built house" , "Inuit building" , "Traditional Inuit house" , "Stacked blocks" , "Home in the far north?" .)
