I am totally in love with Hanne Falkenberg and her knitwear designs; sadly her designs seem to be all in garter stitch (hand knitting).
The one that appeals particularly is 'Dacapo'. It appears to be made up from modular pieces. See http://www.cucumberpatch.co.uk/dacapo.htm (the back of this jacket is particularly attractive).
I am in the process of designing my own knitting machine version, using Designaknit8. So far I have created this layout; it's not easy to explain but each piece is named so hopefully I will know where each piece goes when I get around to creating and constructing it.
I still haven't decided on the stitch pattern - maybe tuck, or 1x1 Birdseye slip ... any suggestions?
The other design I much admire is Diva, see http://www.cucumberpatch.co.uk/diva.htm
