I believe the answer is:

chalet

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

Here is my best explanation:

'a building' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'the church has one leased' is the wordplay.
'the church' becomes 'ch' (common abbreviation).
'has' says to put letters next to each other.
'one' becomes 'a'.
'leased' becomes 'let'.
'ch'+'a'+'let'='CHALET'
