I'm taking it that these are ready made/ready to hang? And are a pair? If so then yeah they should be fine so long as you have the room on either side of your window for the overhang.

Thanks for all your suggestions. I love that sunroof, very cool! Definitely beyond our budget though. We have got a combination of windows and stacked sliders onto the alfresco, I've got the sliders coming from the two rooms so that it can open into one large entertaining space as our family grows up - but perhaps it is overkill. It might look like a lot of living space relative to bedrooms but the 'rumpus' room is really a multipurpose study/guest/games room as we have regular house guests. It will work well for us. I love plantation shutters too - definitely in the plan for front of house. I'm thinking discreet blinds for the open plan area currently, but I'll wait until it's all built to ensure its right for the space - so many decisions to make

Thanks for the support and advice. The house is a fair distance behind ours and its a bit higher. The owner keeps the dogs just for hunting wild pigs and they're in large metal sheds, so the noise is like a speaker across our street. I've approached the owner and he's been known to the council Rangers for 8 years. The noise nuisance orders in place but the dogs are still barking... He doesn't care. I suggested the citronella collars him too. I was informed that a roller shutter over the windows will keep the noise down a little but will only reduce a small dogs bark by 3 Db. Zzzzzzzz.....

It's about balance, between function and aesthetics. Fenestration configuration is often poorly implemented and it can be a "make or break" factor in the project outcome if you're not careful, so good to see that you're thinking about this You want to take cues from the original building style, but you can also nudge it into more contemporary territory successfully if you achieve the right balance. You can always manage/control privacy and sunlight with window furnishings. The most important things are (a) that the window proportions are balanced in the facade, and (b) they are serving the functionality of ventilation & light. On a front facade I'd never design two separate windows side by side that are slightly different, one fixed and one awning - it will look off balance. You'd be better off with two awnings, or one large window with sections of both awning and fixed, say two smaller outside awning/openable with a centralised fixed section. If you do some research in the era/style of the existing home, you'll find that the front facade windows divisions within the one window frame typically were slightly varied. Your picture has them all even that makes it look more standardised.
