As a draughtsman who could produce some cracking drawings of your garden (or a 400 ton heat exchanger) but is still learning what a weed is, I have to say that it really depends on your designer. I've spoken to two really good garden designers who knew their stuff. If you said you needed a private area here they'd suggest plants and architecture to ensure year round cover. The thing is they knew their plants and that made all the difference (I don't know where you are based else I'd recommend them) to my musing when laying out the garden as I could start to imagine more than just the structural elements.
I would do as Dove says and come up with what you want - all year round from the garden - and present a scrap book to a designer (maybe even a different one). Take your tim, loose hours on the likes of Pintrest, and don't be afraid to change your mind if you see something that's better suited for you. If your designer isn't flexible they need changing.
