Hi,

It looks like you have two tilt and turn windows on either side. This restricts a lot of treatments if you want to keep the space open for furniture or window seat..etc. You could put pre-tensioned pleated blinds on each glazed section. These can be operated top down or bottom up. The problem with pleated blinds is that they are very functional but they will not dress the window very well, but perfect for privacy and heat and light control.

Kind Regards

On further inspection of your photo i see that the ceiling in your bay is higher on the inside of the bay so we could do Roman blinds like the one in the pictures below. Have a close look at the sides where we had to do a cut out in the roman in order to get an overlap on the window reveal. You would lose most functionality of the tilt and turns though.
