Catherine the panel blinds could be your solution. They are available in sheers, patterned, mixed etc and operate on a track system. It's an update of the verticals that a lot of homes have. If you have Ikea in NZ you could sus them out there.

Oh, and a few months ago, I was playing around. This is what came as the result :D

Because it's a slider that opens on the left, you should have window treatments that pull open to the right. If you choose curtains that aren't thick or bulky and position the rod so when they're fully opened, they stop just inside of edge of the trim, that should give you a couple inches of space between the trim and the drawers.

Thanks very much for all your feedback. Just to answer a few queries - the deck is directly outside the main room so the new doors open out onto it. The doors won't be French - they're just the only doors that the 3D planner I'm using had, they'll actually be large stacking doors. I've had another idea too which would be a lot more expensive but offers a completely different approach. This is quite rushed so doesn't show accurate layout of kitchen or anything like that, basically just provides an idea. Thoughts!?
