Rentals map adapted and laid out comprehensively (6,4)

I believe the answer is:

master plan

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

'laid out comprehensively' is the definition.
I can't judge whether this definition defines the answer.

'rentals map adapted' is the wordplay.
'adapted' is an anagram indicator.
'rentals'+'map'='rentalsmap'
'rentalsmap' with letters rearranged gives 'MASTER PLAN'.

'and' is the link.

Can you help me to learn more?

(Other definitions for master plan that I've seen before include "Great stratagem" , "Overall strategy" .)

I've seen this clue in The Irish Times.
