Proposal; design (4)
I believe the answer is:
plan
This clue is a double definition.
'proposal' is the first definition.
(a proposal is a plan of action)
'design' is the second definition.
(I know that design can be written as plan)
(Other definitions for plan that I've seen before include "Intend" , "Programme" , "Large-scale map" , "Scheme - map" , "Off the right direction" .)
