Curtains- Window and Door

[FrightenedFTB]

I am looking for some advice on how best to install curtains when the window is very close to the door. I have attached a picture for more clarity.
The length of the wall is 300m, the thing I am not sure of is
a) would it make sense to have two separate curtain rods (150m each) with two pairs of curtains or

b) have a single long curtain rod with two pairs of curtains.

I like the idea of having a long curtain rod because it feels a bit cleaner, any thoughts? If i were to go for this option, any suggestions on where I can find good quality long curtain rods?

Firstly a bit of a note on terminology, I would use rods for a thin fixing that threads through the curtain heading, used for nets and light curtains that aren't drawn.
I use "poles" to mean thicker fittings that have rings or gliders that can be drawn.
Thanks for the picture.
i think two separate treatments would be better. Two long curtains for the door would also cover the security shutters when they are both open.
I would prefer an external fix Roman blind for the window BUT curtains would disguise the shutters better, I think.

@17to35 thank you very much, very useful.

Hi! I think 2 wooden poles and curtains of the same style and colour would fit into your inteior perfectly or a black metal pole to compliment your table and chair. For good poles have a look here - wooden curtain poles
they also have a nice selection of black poles -
