Maybe some simple white roman shades or sheers? I'd go with just above the window and not the ceiling.

I second the thought for simple white sheers, or maybe some simple fabric roller shades? I picked some up for my rental apartment (at Ikea) and it really balances out my apartment.

You'll have a problem w/ roman shades in the corner windows because there isn't enough space between them. The shades would overlap and interfere w/ each other. So, I would suggest a combination of roman shades on the door and small window, and panels on the corner windows. Stack the panels back to the sides of the windows away from the corners and use a fabric that's not too heavy. It looks like you have a beautiful view- don't cover it up!

I agree with Peggy, great view, don't cover at all!

Treat the wallspace to the left as a 3rd window, with drapes or blinds on all 3 it will seem more balanced, it's best if you treat the two 'smaller' windows with lined drapes or lined blinds. Then treat the larger window with a sheer drape or blind or leave it undressed - and - treat the door with a sheer drape or blind or leave it undressed (if privacy isn't an issue). The only area you'll lose view through would be the smaller window so you'd have to decide if balance is that important to you (to lose the view through the smaller window).

Maybe you could put some window-sized art on the third wall, so there will be repetition. or a group of frames that have the same size together as the windows. For curtains I'd go for something white and airy, that's the same size as the windows.

Hang a large mirror with matching molding in the empty space. Treat windows and the mirror with some colorful floaty curtains.

You have windows, a view and some architectural interest going on.....,more than half of the people here would be jumping with joy.

All you need is roller shades if anything at all....

And before "balancing" anything, try getting all your stuff in the room and see how it works... then... go to the windows....

What about using white venetian blinds?
That way you can cover or uncover your windows according to your needs.

Are you at 1443 Beacon in Brookline? Look what others use. I'd leave it alone and enjoy the view and maybe rolldown shades if you want to sleep in late.

There's really no design rule that windows must be symetrical with a room or made to look so. Given that you have a view and appear well above the ground, unless you have a solar problem with the windows, you can just leave them uncovered. As an alternative you can hang a window scarf-type arrangement across the tops and down the sides of the windows. This would serve to soften the edges of the windows while helping you maintain an unobstructed view. If you have a solar problem, translucent fabric or film solar shades may be a solution, these reflect strong sunlight without blocking views.

I'd go for some really dramatic asymmetric window treatments as well. Sheers all the way across, then a really bold swag draping from the one corner, up in the center, then falling to the floor on the opposite corner.

I always cringe and wonder why designers/developers put those very dark colored window frames in any development, but especially one where the view has such a distant focal point like this one does. They're so harsh and so distracting! That being said, this is a wonderful space you have with lovely views-congratulations on a great place! I would lessen the pull the dark color of the window frames has on the eye by putting some floorlength drapes with a similar color to the walls so the frames don't assault the eye the way they do when bare. Your eye will easily sweep the room and be able to shift to the view and back again and it will look less asymetrical.

i would embrace the asymmetry if i were you... its a good change and besides, you have a view...

I wouldn't try to 'hide' it- that rarely works well & people can usually tell what you're up to. While the asymmetry is quirky, it's not too unusual. I like all the simple, light & airy suggestions above. But my first thought agrees with NAV- I'd get some art roughly the same size as the windows & hang on the adjacent wall to help balance the visual weight. If you can't find/afford anything you really love, try checking out Michael's & buying a blank canvas. Even if you don't have an artistic bone in your body, there are a TON of easy, attractive DIY ideas you could implement- you could even use collage, stencils, etc... Heck... painting it a solid color could even work! :) GL!

If you wanted symmetry - Why did you choose this apartment? Just go with it rather than trying to make it into something it's not - I'd use simple floor-to-ceiling curtain panels...

...just be sure to balance the height of the curtains with another tall piece on the side of the room that doesn't have windows using something such as a tall floor clock or a long narrow piece of artwork.

I have the same window in my bedroom! (though, I'm in AZ and NEED window coverings.

I used floor to ceiling white sheers on all three walls. The 2 windows have privacy honeycomb shades (for the blaring sun).

I recently added an oversized mirror to the windowless wall. Just set it on the floor in front of the sheers, it reflects the light and looks really nice. I can send you a picture if ya like! :)

I agree with prettybee. Embrace the asymmetry. The view is wonderful and any attempt to divide the room would diminish its best feature.

The window treatments, or at least the window treatments alone, will not create the balance you're looking for. That will come with what else you place in the room, and where.

After you address the function of the window treatment (solar shades?) you could do a dummy drapery panel on the blank wall immediately to the side of each two-part window. Make it heavy enough in weight (not necessarily color) so it appears as if it is covering the third pane.

And to the people saying "Don't cover the view!!!!" relax... window treatments, if done right, enhance the view even if (God forbid!!) an inch or two of window opening ends up being covered.

I'm presuming the door leads to a balcony up high -- no privacy issues?

I'd just hang draperies over each window and maybe the door, floor to ceiling (or at least to the top of the window), and open or close them as desired. If you love symmetry, implement it in the other decor -- matching end tables with lamps or whatever rings your bells. (Frankly, symmetry seems safe and boring to me -- I'd enjoy the asymmetry a lot! But if you prefer the symmetrical, just do it everywhere else. It will be fine.)

Why not just embrace the oddness and hang curtains over the small angled wall space next to the window? Or hang sheers over the windows and a heavier drape panel on the wall space if you need more privacy? Easy to do and it will create the illusion the windows are complete bay windows, adding symetry (sp?) to the rooms.

I actually don't quite see the problem with your windows...

Have a look at this picture...
