I love that colorful floral!! it almost has a 40 vibe, and glamorous - I think it would look great in small toilet, maybe matte gold color mirror frame (and everything else white). The other floral is more retro - I prefer the glamorous florar. For the bathroom, if its a paper wallpaper I wouldn't use it beause of the moisture from showers might have the paper corners come off, and you can't really clean it - so I would skip wallpaper there. I love wallpaper and the drama it gives, but it has it challenges. But I like your choises so far, so you are on the right track. If you do something for the lounge I would do something geometric, and monogromatic more subtle.

I'm no architect, but I agree with yours. Instead of large windows in the loft above the garage, what about a high, short, but long window....non opening? Here's some examples

Yes the windows are in place and I’m sorry I didn’t see this before we had to make some decisions

Provided there is 1200mm clear between the breakfast bar and the opposite bench then by rights, you should have ample room and if that's the case, I think I would opt for the design with the kitchen on the eastern side. My reason; you get a much greater feeling of open plan by having the dining and lounge on the North/South plane. I like the large WIP in this one - on paper at least. The second plan somehow feels wrong. I personally don't like the idea of having the breakfast bar being located in the lounge. If it were me though, I would ask for a 3D CAD plan of both kitchens [to walk through on the computer] before making up my mind on which one to opt for as it gives you a much clearer vision of what the finished kitchen will be like rather than looking at a flat plan.
