I have focused my energy of plan therefore i have worked out three options 1,2,&3.Every option have at least living room with kitchen (solutions with modular and can be separated with rest of living room) .
Highlights for each plan are as follows :-
OPTION 1:- with car parking along with no loft.
OPTION 2:-with car parking along with no loft.(SAME AS OPTION-1 but the wash is smaller and kitchen location is next car parking.
OPTION 3:- without the parking space but instead with space on the ground level for storage of 4 bicycles, a double stroller, and steel wire shelves.
GOOD LUCK FOR YOUR PROJECT
P.S:-for dimensions check dwg and all dimensions are in inchs
