I concur with the above comment: Just have archways installed rather than doors - not only will it be more open but it will be less costly... ...tho to open the living room even more, consider relocating the LR fireplace to the opposite wall and centering a larger archway to the hall opposite it - where the fireplace is located now. I might also consider installing an archway or doorway to the left of the fireplace in the sitting room - It will make your sitting room less of a dead end and passage to your study, kitchen and powder room more direct.

fragle0 ... congratulations on the new addition to your family. Have been following your lovely changes. You probably won't have time to work on the decor for a while. Just wanted to suggest that you try pulling the nesting tables forward to be more in line with front of the chairs & placing your floor lamp to the back of them. This will give a bit more light at night for reading in that area.Also switching the plant by the fireplace & the one on the corner by the sofa.

If you have the money and the means,do all of the floors the same ,that way it has a continuos flow throughout

It feels bland because floors and walls are beige. (ish). If you want to make a statement about a room. contrasting shades work really well. You have spotlights so the south aspect is irrelevant. Put a dimmer on spots if not already there so you control the light and feel of a room. I presume the fire is staying there so that back wall would be perfect for TV to be put on/entertainment system. Corner couch facing tv wall with chaise lounge on fire side. Behind the corner or L shaped couch, table and chairs so the room is functional for entertaining also and the layout is proportional. The room also has a focal point (TV)
