Drapes clear across. grommet top from just below ceiling to the floor. You can use almost any color. If you want to stay monochromatic use a wheat color linen. If you want to go color the world is your oyster.

My initial thought was the shades. But after looking at the pic again it seems this room might be even darker if you cut off the window. You seem to have a nice view. So I say drapes on both sides hung as high as possible. since your furnishings are in the beige tones I would opt for drapes that have a tad of color to give the room a pop. There are lots of patterns out there that would look great.

Curtains panels, hung as high and wide as possible to let all that light in. Color is up to you...but looks like something with rust and creams would coordinate nicely.

Maybe even pull in that green from the glass globe on your hearth if you want more color.

Simple pleated panels..hung high over a simple wooden blind that compliments the space...

Perfect 10!

I have a few blog posts that may help you out.

When choosing window treatments the first thing to consider is function. Do you have a privacy issue, a sun issue? My windows in the living and dining area face west. Our summers are hot (105 degrees). I have vertical fabric blinds installed ceiling to floor. I can pull the blinds across the windows and turn the slats during the day blocking the sun but still let in light and some view lines to the outside.

The other thing to consider is aesthetics. What type of look are you going for? Your room is lovely, very clean and neutral. It is quite angular with all the square shapes in the room, sofa, chairs, fireplace. Roman shades themselves are an angular look. They will highlight your windows showing the rectangle shape. Draperies will soften the windows and still allow your windows to show.

If you don't have any privacy or sun issues, I would choose a simple full (width 3 times), floor to ceiling drapery. Treat your windows as one unit and stack the draperies on both sides, so when pulled they meet in the middle of the windows. I imagine something soft, translucent (if privacy isn't an issue). They should flow across your windows and hang softly with gentle folds. Your fabric could be plain and neutral, patterned, or tone on tone.

I hope you post after pics. Would love to see the completed room. :-)

Light filtering cellular shades will diffuse light and help with privacy. These could be flanked with simple drapery panels.

Light filtering organic shades with simple panels on either side would be perfect.

The arrangement is off so I think that has to get addressed first. Move the couch under the window, so the couch doesn't block the stairs, bring the two chairs across from the couch and get panels for the windows. the panels will frame the couch beautifually. The space is so bright and beautiful but the arrangement is killing me. Do you need the third chair?

Consider some bamboo or woven grass roman shade layered under simple straight hanging curtain panels from decorative rods mounted slightly higher than the top of the window trim

Agree with suggestions by others...bamboo woven roman shades layered with tailored linen or cotton panels would look really nice in your room.

I agree, the chair that matches the sofa isn't working. You might try to do a right angle with the sofa and the chair. Have the arms touch then there would be a square of space between sofa and chair. Maybe add a table + lamp in the square. Try it in front of the window as tennis anyone suggested or where it is now. Removing the chair would be easier.

Curtains would work best.

I agree awith Joy. Roman shades would look very nice and you can even make them out of sheer fabric if you want and the sunlight factor works there. Inoperable drapes at the end of the windows add a nice touch and give the window a finished look. I include a photo of a room I did with romans and drapes.

Hey There: window treatments have a design purpose and a practical purpose - light and privacy management and some passive temperature control too. Our suggestion is to use individual pleated bottom up - top down shades for the windows. These blinds almost fully collapse when open and do not cover any glass surface. This way you can manage the light and privacy challenge. Additionally, you should frame it in with a beautiful non-functional curtain that goes all across. We do have a video on our website www.PleatedBlindsStore that shows you the installation and the outcome of these shades in traditional windows/doors.

A non-functional curtain that goes all the way across is functional. It's operable if it goes all the way across. Drapes that are only at the ends and don't go all the way across are non-operable. What you are suggesting sounds like cellular or honeycomb shades that do save heat loss up to 50%. You can also get custom shades that are top down/bottom up in fabrics as well.

My bet. It should be a NON functional curtain with only the rod all the way across...this way you don't have a stack of fabric hanging on either side...

Pleated shades are an option, however the "stack" on cellular / honeycombs shades is not significantly different.
