since you can't do blinds, looks like the only option are drapes. will the bed be going in that spot?

whats going outside the window? will there be a fence? what about if you planted some tall plants as a divider and 'shield' from the neighbors?

Two panels from the ceiling on a sides of that spot.

2 simple (maybe solar) shades on bottom 4 window panels.

hey jack, how is she supposed to attach 3 separate blinds?

Zen has a good idea. just run the blinds on the outer ends and attach them to the solid part in the middle. this would keep the entire top section open.

it would basically look like this one in the middle

This is simple. Have your windows tinted. We did that to our Sunrise room and even with ones nose pressed against the glass from outside all we can see is blurry shapes. They will keep the room cooler too.
