I'm not against colorful homes. There's bright, and then there's too bright. I wouldn't go with persimmon for the whole house. The photo you provided has lots of white trim which offsets the orange, but your house doesn't have that much trim (unless you were planning on adding some, which I think would look good no matter what color you ultimately choose, but even so, I wouldn't go with persimmon for the whole house, as it's still too bright). To repeat what @nwduck said, the other homes in the neighborhood don't appear to all be done in the bright colors, and so yours would stand out too too much. I like @deco's idea of the bright door, if you really love a bright color. For the rest of the house, any more subdued color would be fine, along with additional trim around the windows, and assuming that your siding color coordinates with your roofing color.

you are thinking about the space right now. it looks odd, no doubt. 1) when you fill in with the furniture, just make sure the three steps are hidden. 2) consider three potted plants of different height, so the rectangle is complete. 3) glass bowl with Siamese fighting fish for each step 4) figurines of different heights 5) 2inch square wooden bar on each step up to the top of the rectangle. and complete the entire rectangle if you want with a smaller rectangle open in the center my suggestion is, there is a reason why this space ended up like this. it will look great once you put something there. things like these are what make your house unique.

Hi Nikita, First and farmost, you have very beautifull coushion on sofa, from where you buy it? You can check the videos of Small budget Big makover first session series in youtube. In One such house in Gujarat, Muninder and Bishakha coloured the old sofa set with whtie (The sofa is like yours) and changed the centre table. Interestingly, the family also had your kind of sofa set and they also want some modern style. The architect duo did not changed the sofa, just changed the colour. Yes I found it in youtube. it is the house of Setu Upadhyay. the link is https://www.youtube.com/watch?v=85GNhyLeVnM Another suggestion is that you have many tables on the room. You can drop few chairs and opt for a single centre table

I have some suggestions if you are thinking budget friendly changes. Make a photo gallery with different size frames and arrange them parallel to the stairs, so you can enjoy each photo as you climb up. And for the area that will be on a level with your upper floor, try some pretty decal that will connect the photo gallery to upper level. And last, if you have budget add some beautiful hanging lights in the stairwell. Also think about repositioning your refrigerator.
