Here's a thought with the walls down. When I got the sink out of the corner, more possibilities opened up. The semi-automatic dishwasher still has a nice view. And doesn't have to step away if another person wants to have a second at the sink. Here is a link that might be useful: IKEA 3D Planner - link good for 5 days

I think this is one of these things that should have a "post-game analysis" of sorts. I don't mean to be critical, but this will be analytical and it may help someone else who builds a house in the future. The idea here is nice, and the essentially linked windows are similar to a true palladian window, with the tall window in the middle and subordinate windows on either side of a height equal to the bottom sash...fine. But you've kind of backed yourself into a design corner because these particular windows need to be covered, and yet you don't want to cover them too much, or all the time. A palladian window in an 18th or 19th c house would be treated like this: The walls would be thick enough that shutters would fold over the small windows and fold back into shallow pockets in the jambs when you wanted them out of the way. The larger window would be elaborately draped because of the curve or possibly mostly left bare,depending. If you were to design this over again---or if your architect does do this again in another house---a peak that was wide enough to allow a single rod or top mounted treatment that was wide enough to cover all three windows completely should be one thing considered, or more room for shutters to be folded back would be another, a shorter or differently proportioned window in the middle another. I think that windows are often designed as if they can all be left uncovered because nobody's windows need to be covered for privacy or light control. And really the opposite is true. Almost Every window should be designed if it will need to be covered for privacy or light control, and if it doesn't great, but if it does you are not faced with several less than ideal options and possibly some really awkward options but no perfect options.

I'm thinking that in addition to the added screening, some behaviour modification might be in order. For the neighbours of course, not you. Unless you're spending time watching them watch you lol. How young is young? If they're preteen-teen a knock on their door and a chat with the parents might make a big difference in the time they spend observing you. Kids are naturally curious. And teens are naturally, well, teens. The adults might even consider adding some screening to their window once they know this situation exists. If they are grown men that's different. Do they actually stand and look in (an offense) or is it your perception of a need to be more discreet because of their presence? Which is of course perfectly justifiable.

Consider a sleep mask rather than window coverings. This solves the issue without ruining the beauty of the windows. I would leave them without any window treatment at all. Maybe film to reduce the glare. It looks like you have privacy already with just a tree view.
