I've designed a dual occupancy development, can someone please take a look at it and see if any more passive heating can be achieved to unit 1?
There is a raked ceiling with clerestory windows to the first floor but Im not sure what i could do to the ground floor.

Great that you're thinking of passive solar in a duplex development!
I've had a look, but unfortunately I really can't think of anything that'd help the ground floor; normally I'd suggest a courtyard or similar, but it doesn't look like there's the necessary space available. Unit 2 is definitely going to be the nicer one to live in.
My only concrete suggestion would be to make the Unit 1 master(? - the westerly one on the upper floor) an exact mirror of Unit 2 - it'd be much better making the bedroom window face south instead of west..
