A couple of things from me. Firstly, the cornice painted a yellow makes the ceilings feel lower than necessary, paint them out white or as per tour ceiling rather than accentuate the highest perimeter moulding, you don't want yo draw attention to the highest detail not being high! Secondly, to make the room feel fully addressed the window has to be looked at in context of your room. The house style is important, but more so the room space and light. As you have a verandah you probably have in direct sunlight, but the room is not large, so i would try to make the window feel part of the bigger picture rather than contrast with it. Which is what the red does, effectively looks like a red rectangle dominating a small wall. Do the opposite, taking colour cues from the room will make it feel unified, therefore bigger. The caramel carpet, for me is where I would draw upwards from. I suggest a rattan roman blind, the texture and stiffness will resolve that terrible sag, let in diffused light and provide a natural element needed in country style schemes. It allows the scenery to stand out, and colour is easily built upon it. If you need further blackout, you can install a uv cheap roller blind within the window frame, which would be hidden from view by the roman blind, so it can remain up most times and the roman can frame the beautiful view, allow light and then use the roller as your night privacy blackout blind. Most Romans look best as a frame treatment, they dress the window better than they function on them. Shutters would also be stunning with their play and filtering of light, but costly. And just a tip, your bed would feel far more luxurious in that space if it were not heavy in colour, the metal and timber, both which are not genuine as in fake cast iron and artificially stained orange pine date your space, that is not a dig, just an observation. You could do an upholstered bedhead for a luxurious look that a linen would tie in with the soft furnishings, you can address colour in many ways, but the blinds, carpet and bedhead should be neutral unless you can afford to upgrade often?.. A layering of texture and tones rather than colour is far softer in a country space, that's why it's done often, creamy whites on a caramel carpet will really brighten and freshen that space, , timber lamp bases, fabric shades, plush pillows and personality pieces, you'll have a space you can't wait to get to. I hope this was helpful!

I actually love the combination of timber, jute, rattan or patterned blinds with white sheer curtains. It's especially lovely if you want the option of either blocking light or letting the most in without letting your windows look too naked. These photos may help you decide:

Oh okay, so it's a new house you are moving into? Congrats! So you will have to wait till you have keys to start arranging measure and quotes. Luxaflex seems to be a high quality well established manufacturer. However, there are others with quality products and service as well. My only experience was through curtain & blind suppliers, and service was very good. They will come to your house with sample books and also provide advise about the various products. If they can't tell you about how much block out or UV protection their blinds provide, then ask them to find out. I would think if they were good, they would know this information. I hope this helps.

Zaffa, if you pop down to your local Spotlight store, they have examples of all types of blinds and shutters Great to get an idea of what each look like, various options, pricing, etc, etc. Only, NEVER EVER order shutters from them! I ordered mine from them when building and they took longer than the house to make them! Ended up having to use temporary blinds for months until they arrived. Also, they really let a lot of light in, so not great for kids bedrooms at all! Romans and rollers keep out much more light if you don't want to go down the full curtain with pelmet option. You can also go automatic blinds with rollers if you're concerned about boys touching the blinds too much. Adds around $500 per window I think I was quoted, so depends on your budget. Cannot automate roman blinds apparently. Best of luck in your decision.
