I think you really need to look at the costs associated with moving walls and the kitchen and bath to get an office and curved stairs. The easiest and cheapest solution is to put your office in either bedroom and leave the floor plan the same. Take the money and time you save to update the kitchen and bath fixtures if needed but You still have not shown us what you are starting with except the stairs. Please post pictures of your current space! I think this is a waste of time and money unless you've found that money tree I've heard of. Good luck though. We really DO need more info from you to give you better solutions.

What kind of work will you do in this office? If the chairs are for clients, then small tables next to each (like for a drink of water) would be good and I would not do any ottomans. If you’re alone in there and these chairs are for you to relax, then ottomans are fine. Whatever you use this office for, make sure the chair is SUPER comfortable and supports your back. Love the rug in the photo with the leather chairs. Is that being considered, or already purchased?

@einportlandor ouhhh I like that idea! do you think it will match nicely ? please see updated colors in original post. The bookcases are a king of metallic-ish charcoal. Do you think that would clash? Light fixtures are silvery-pewter (can change if necessary) and feet of velvet blue armchairs are brassy-brushed gold. What should I do metal wise and will it marry well with burnt orange? I think burnt orange could be good to go with the honey oak trims and taupey floors too- what do we think? @kandrewspa thanks for your input! love the color recommendations. Do you think it will match the rest? See additions to original posts re better view of colors. Also what is your opinion on colors for metals that I should use? If I understood correctly, you would put the bookcase on wall A and the desk straight in front of wall A facing the current door (see annotated plan please)? @Molly please see updated post, I think it will help! Love your suggestions and Yes, I would love to see outside as well. Do you think an L shaped desk might help with one side pointing towards outside? I'll have both a screen and laptop so my screen can be my laptop when I want to move. So shelves on wall B in your opinion (see anotated plan in original post)? Love the rugs! what are your thoughts on colors for metals I should use? @housegal200 love your ideas! Could you kindly take a look at the updated annotated plan I posted on original post and tell me which wall you are referring to? I want to be sure I'm clearly visualizing the plan you are proposing please (I'm extremely visual lol) Thanks so much!! love love that rug and table as well, but am worried about metals clashing with metallic charcoal bookcases + current silvery-pewter light fixtures (can be changed if necessary). I added more pics of these on my original post as well. I updated the plans in OG post to keep it simple as well, I think it was adding to confusion if anything, unfortunately the big closet with mirrored doors is not part of the office and is accessible only through a complete other section of the home. No closed closet space will exist once the door on wall D becomes the clients' entry point. Can't wait to get more amazing feedback from you all. Thanks again a thousand times! This is our first apartment, so it's definitely a first in decorating for me, your help is so very appreciated 🙏😄

There are lots of websites that will allow you to try out rugs in your room 'virtually' to see how the rug complements your finishes and furniture. Here are some examples. Also, you might consider purchasing a small-size rug to check for color & quality before you commit to having a heavy, large rug shipped to your home. Good luck.
