I think just removing the wallpaper and and painting (instead of adding more wallpaper) would make a big difference (particularly in the bathroom). Also, I would get rid of the current mirror in the bathroom and replace with a smaller framed type, paint the cabinet and new hardware. Honestly, I think just paint will make a world of difference in your space.

Hi everyone, we have moved in! We didn't manage to paint before we moved and think we will go for a staged approach - above the wood panels first in a warm white then decide on the panels. I'm having a bit of trouble working out what kind of sofa to buy and how at arrange the lounge. All furniture except coffee table temporary in photos and would love some ideas!

I'd fire that kitchen design person lol. No such thing as a corner pantry being outdated. I would bet she is new to the biz and has no real clue. If you have the space, then go for it. I have a closet in my kitchen that is considered a pantry, but kinda wish it was just a large floor to ceiling cabinet. I have a base and wall corner cabinet that I started to use for mostly canned and dry foods and it works much better because it's closer to my stove. Whatever works for you the way you use your kitchen would be the way to go :)

If it's brand new, have you tried asking the supplier what they recommend? We got a booklet from our supplier when we got new carpet with ways to treat various stains on that particular carpet. Each kind of carpet will be different. Also, have you tried a professional carpet cleaner? If all else fails, try your luck with your insurance company - I know others who have got carpet replaced because of bad stains - depends on your policy.
