Out of your selection - I would choose the middle one on the bottom row - it gives you a modern look and pattern without being too ghastly - it would fit in with the retro vibe as well. Good luck!

I think you can very well still have plants in a windowless room- as long as you're willing to give them regular little 'windowsill holidays' in another room. I'd go with succulents, there are some great warm colour combos (see Pinterest for ideas) and the geometric shapes mimic your tiles. Of course, there are some incredible fake ones around too, saw one last week I could not pick from the real thing. I'd be tempted to mix in some of both to balance aesthetics with practicality! Separately, I'd be careful of adding any soft furnishings (rugs, spare towels, etc) to a small powder room. We are all aware these days that a flushed loo spreads germs a meter around it- I wouldn't want to be collecting and trapping them! I think (subtle) fragrance and votives would warm this lovely space without impeding hygiene.

I think the decision rests with whether you NEED a butlers pantry! No point in putting one in just because the room is there. But as one post suggested you could loose the current pantry, thus enlarging the family room, and then you maybe have need for a large pantry. I am a little dubious about a 'butlers pantry' idea in general - a storage pantry is most useful but having appliances etc in another room just means more walking from room to room during meal preparation. I think deciding to include a butlers pantry would require a great deal of thought on exactly how you would use the space. A cleanup space - yes that could be handy; where dishes and pots could be stashed during a meal, saving the kitchen proper for serving up. Still means a lot of walking! I think the kitchen work triangle is still a useful concept! And those big island benches with a sink - so your guests can sit and chat while you cook, and watch the dishes piling up under their noses? Ugh! Not for me! They look lovely when clean and EMPTY, but as a usable sociable area, not practical. (Sorry for the rant; has nothing to do with your question or your kitchen, but this is a bugbear of mine!)

@girlguides - all projects, no matter what they are, come down to simply a process of sequential decision-making. The individual decisions are not rocket science and when broken down logically everybody and anybody has the capacity to make the decisions.....when people/clients say to me "I'm hopeless I can't decide, I'm not good with decisions etc " my response in one form or another is "No, you in fact can do this, you just need some clarity and guidance" Without getting too deep into it, (and it's a separate conversation/story), years of university study proved somewhat disconnected from the "real world" of design & architecture. However there was one particular lesson/concept that's stayed with me and seems to inherently apply daily to what we do: 'design (or project) decisions require a sound reason and bulletproof argument' . That's all there is to it really. You do/follow this and it naturally steers towards both viable and appealing outcomes, as the decision making is always grounded, with some sense of purpose logic and confidence. Where I find people getting stuck or lost with it all is when the path of decision-making has either been pursued out of logical sequence or has become compromised (or contaminated!) by irrelevance to the particular situation. I always endeavour to starting with fundamental aspects, derived from the client (personal preferences/requirements) and of course the contextual elements and limitations. From that point, you always have a solid foundation to build project decisions upon and you can always then refer back to it at times of being stuck or overwhelmed. If you're caught on something, break it down and take it back a little, regain the footing/hold, then continue. Regardless of a project's scale or complexity understanding and implementing these basics can go a long way to avoiding projects getting off track or ending up at the wrong place if you know what I'm saying ;) Cheers PD
