A big house for dad to do up (6)

I believe the answer is:

palace

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

'a big house' is the definition.
'palace' can be an answer for 'house' (palace is a kind of house). I'm unsure of the 'a big' bit.

'dad to do up' is the wordplay.
'dad' becomes 'pa' (both can mean one's father).
'to do up' becomes 'lace' (as in doing up your shoelaces).
'pa'+'lace'='PALACE'

'for' is the link.

Can you help me to learn more?

(Other definitions for palace that I've seen before include "Sovereign's residence" , "See 16" , "Locality round a monarch's official residence" , "Castle" , "Royal residence" .)
