I do like your idea of an ottoman instead of a traditional coffee table. Since you have a fairly mod/hip style going, you should find something equal. I do like the one that is tufted all around but of course in some other color for your room. Something low and sleek.

I think a clear (Lucite?) console table would work well, with perhaps a plant in nice timber plant stand and possibly a decorative basket underneath. A smallish bowl on table could serve as a holder for keys, sunglasses, etc., unless you already have a drop-off point in entryway. I do like idea of other for potted plant in hall upstairs, but perhaps not in path of stairs, esp with those two doors located there. Here are photos to give idea.

Hi, Pin down a builder? I would suggest you take the plans you have to a builder and get some feedback before you go much further. Builders are often your best ally when it comes to practical ways to achieve the design intent.... many is the time we have been asked to price a set of plans where the client has invested an inordinate amount of time and money on detail only to receive a rude shock when the reality hits the budget for all the detail desired.... cheers

I’m set up in our sunny spare bedroom. Happy with my spot as I have views to the street and a desk to work from.
