My home area, surrounded by fine architectural style (10)

I believe the answer is:

corinthian

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

'architectural style' is the definition.
'Corinthian' can be an answer for 'style' (thesaurus). I'm not sure about the 'architectural' bit.

'my home area surrounded by fine' is the wordplay.
'my' becomes 'cor' (both are expressions of surprise).
'home' becomes 'in' ('he's home' can mean 'he's in').
'area' becomes 'a' (maths abbreviation).
'surrounded by' indicates putting letters inside.
'fine' becomes 'thin' (similar in meaning).
'a' going inside 'thin' is 'thian'.
'cor'+'in'+'thian'='CORINTHIAN'

Can you help me to learn more?

(Another definition for corinthian that I've seen is " Recipient of Paul's letter".)

I've seen this clue in The Telegraph.
