Since the lot you describe is smaller than my open living area, I would suggest looking at some of the "shotgun" house plans around New Orleans,LA. I think you can build up and back and get an interesting home with a loft for space. It can be done, A porch with an entry to a narrow hall at the back might work best for you. Will you plan a courtyard (closed)? or what? What part of the country are you in? What are your local codes?

thanks all for replies. I want to highlight the wall as rest walls are almost white and need some change. there are white tiles on the floor, red sofa set and mostly brown furniture. I have planned to give a grey texture on the front wall (hoping it will look nice with red sofa). the wall beneath the light( in the photo) will continue to be white. though I would like to highlight it in some way as I have kept a box console in the photo above which a round mirror will be hanged. pls suggest

@Studio Chippan, Thank you, for your response and the reference pictures. It offered me helpful insights. I agree with you regarding the 3rd-photo. This illustrates that 3 paint colours in my living-room will not work (even if 2 of them are white!). This also means that I can no longer go with 8300/Confetti as my choice of white for walls (as much as I like it, it will dull/dim my rooms if I paint that on my ceilings as well, especially my north-facing rooms). So now, I need to find 1 single-white that can go/complement with my 2 adjacent accent walls in 8307/Quicksilver, and that can be used on my ceilings as well (and the walls and ceilings of all the other rooms). Any suggestions? So far I have sampled the following Asian/royal white(ish) shades (I’ve added my take on them beside it, but it is only my own perception of these shades): 1) Base White (the one without any tint): boring, clinical, too bright a white for walls 2) 8300 /Confetti: not too cold, not too warm, my favorite white among the ones sampled, but too dull for the ceiling 3) L104/Cotton Wool: seems to have a slight-pink-undertone(?) on my walls, too bright a white for walls 4) L109/Icy Peak: boring, slight-green-undertone(?), but might work for my walls+ceilings requirement 5) 8332/Snowflake: this is a very nice grey, but I am looking for a white (for walls+ceilings) 6) 8308/Whispering Smoke: this is a very nice grey, but I am looking for a white (for walls+ceilings) 7) 9483/Clear Sky Night: this is a nice grey, but I am looking for a white (for walls+ceilings) 8) 8299/Ice Age: this is a nice grey, but I am looking for a white (for walls+ceilings) 9) 8292/White Gold: this is too warm a white (strong pink/peach undertones!), ruled-out. Why 8307/Quicksilver, and why 2 accent walls (if I may call it that) instead of 1? This particular vertical-line of the fan-colour-deck is the best match with a wallpaper that will be applied on an exposed beam (~L:15’+15’*H:1.5’*D:4”) running along the ceiling on 2 of my living room walls. Shades along this deck-line are: 8308/Whispering-Smoke (one of the whites you suggested above, but too light a grey for accent), 8307/Quicksilver (seems like the right density for me), 0615/Silver Grey (gets too dark for me from here), 0643/Steel Grey, etc… *Disclaimer: I do not claim to be a minimalist; I am merely trying to be one. However, I did not succeed with my living room design; and now I only hope it doesn’t get out of hand and OTT.
