With tilt and turn windows I can only think of two options, either face mounted shutters to the actual window, which the fabricator might offer, or a rod hung on the face of wall above the window opening, to avoid the window catching on them. A track sheer or drape will work aesthetically, but practically?? Presuming when the windows open, so too would the curtain, it only matters at the end of day when you want to close up and have privacy, so perhaps a holland blind (pull down) so it's least conspicuous.

I suggest the very first thing to do , would be to decide your budget and what you want to achieve , and to a certain degree what the suburb is like ? If it's the 'worst' house in an upmarket suburb , then $100K or even $200k may really lift its value , but if its in a 'cheaper' suburb , you may over capitalise . Like others , some things I'd look at -- -- Do the gardens , trim the tree , looks more like rank grass along the side of the driveway ? Maybe a white stone garden , with a Yukka ort similar . -- The concrete driveway looks 'drunk' , but that may be because of the shapes it was laid in ? Level it , take the front out to the street , talk to an expert about doing a one-run top coat of concrete . -- Remove the fairy lights , relocate the satelite dish . -- Personally , Id frame upwards on the top of the carport and lounge roof , and also the first floor roof , and put bright 25-30cm tall painted or powder coasted alloy panels -- cover the gutters and 'hide' the solar panels . Paint or coat them whatever colour you like , but I'd go for something like bright yellow or orange or red , mid blue , a crisp green ? -- Someone suggested brown wooden 'louvres' full-length over the upstairs windows . I'd be tempted to go with that idea ( buy 30mmx30mm pine , and a mid brown stain -- 6 or 8 'rails' along that upstairs on the side and front you can see in the pictures . Instead of mid-brown stain , a black/charcoal may suit better , especially if you go with those bright panels . -- Maybe a fence in the same 30 x 30 horizontal wood , same stain colour -- ties the upstairs to the 'ground' level ? Relatively budget , and can be done in several steps , but would 'lift' it no end IMO .

I would go for drapes sitting high up to the ceiling and have the same for both windows shown in the picture (tracks at same level). Perhaps something with texture or pattern that has the tones of the wall paint colour. Lots of options with double track systems if want a soft voile for screening or to break the light. You can also do as Julie suggested as well as put curtains up to soften the space.

To my eye the only thing your house lacks is floral aspect in the garden. You have some lovely foliage but florals make a bush block come alive. Some beautiful grevillieas will bring birds, moonlight is my favourite as the white florals really lift a landscape. Leucospermums are dramatic and come in sunset colours that work so well on bush sites. Pandorea are a native vine that's extremely fast growing popular with nectar feeders and comes in a huge range of colours. The flowers appear in massive sprays in early spring. Would look great on your porch, Unlike wisteria it won't harm the structure it grows on and is easy to chop back. I really love the sunset one. But they range in everything from pure white to deep red and many bicoloured like this one. And for a light, airy bush with some different try the honey lace myrtles, the bees will love them. In the darker aspects of the yard you can tuck brake fern in those spaces to bring them alive and make the site appear more lush.
