From what I can see, the only way to enter and exit the laundry is from the outdoors. Is this intentional? Would you never see yourself or someone else in family popping into the laundry to run a load of clothes? Or wash a dog in the laundry sink? Maybe this is the way it is there?

Just a few thoughts. I like the overall concept of the kitchen but it is rather disjointed. I agree with clearing everything off the surfaces and trying to keep them free miss a feature bowl for the island. You could add an eating area as this would make it more purposeful but I would not do it if it compromised the size and functionality of your living area. The piece of timber joining the two walls at the entrance seems superfluous and I if was removed it would instantly look more contemporary. You could extend those walls up to the height of the cabinets and repaint in a lighter colour. This could reduce your light but this can be dealt with in other ways. I love wood cabinets but the top ones up look heavy- perhaps they could be painted a light colour to reflect the light coming in from the entrance but I would revisit your lighting in general. There is a lot of timber with the floor, cabinets and ceiling and this makes the space quite dark? if you did extend your walls you might find the kitchen darker so paint cabinets. I like the idea of wallpaper but only if you have an even shaped wall and if the pattern works with your living scheme. Whatever you do with your walls will need to correspond with the adjacent entrance walls. You didn't mention your budget but I would start at the simple end and if it doesn't give you the result you want move to the more complex solutions. All the best

I think the 6 pane one will suit the house. We have 4 pane ones as bifolds for our studio which was converted from our garage. (first pic) I had to google 'hopscotch' windows. If similar to the ones below, I think they will suit your weatherboard. Which colour will you be painting your house?

I'd be worried that red brick , presumably white door jambs , then a walnut or mahogony ( dark walnut ) look door will look cliched 70's . A cedar or even something like Jarrah will be different enough to the brick ( again , making the assumption you have crisp white or similar to break the tones ) to look the part IMO . Of course , the actual design of the door will have a slight bearing , but personally I can't think of too many options where I would prefer a walnut or mahogony tone , unless you were really embracing the era and have yellow dimpled glass inserts too haha .
