Does this village have any colonial features? The house has too much concrete and nothing to warm it up. Use natural wood hand-made railings...not painted. Balance the railings. Upper railings and lower railings are completely different. They should be taller...a meter high upstairs. Do you have to leave the upper columns by the bedrooms exposed? Bring the brick wall between them forward so the columns are inside the house. Divide the casement windows with 4 panes.

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.

My drawing room front Window is going to be of around four feet wide. As the width of this room front wall is 10 feet out of which 3'6" will be kept for front entrance door. I am confused whether the sill height of the window should be 6 inches or 3 feet high as sofa is coming in front of it as my drawing room size is 10'0" * 14'0".

Thanks a lot for your valuable suggestions and comments Rusty Empire,decoenthusiaste,emmarene & Chikka BangBang. My home is located in a small village in India. We initially planned to renovate our old home. But during the middle of renovation work, we changed our mindset to build a new one. Hence we made a house design by ourselves(3BHK) with the help of our local builder and to save the cost we tried to reuse all possible materials that were extracted while demolishing our old home((i.e.., like red tiles placed on the top of left side of porch). The project is in last phase, now I feel that still we could do something to enhance the beauty of exterior of home by getting some ideas from experts. I like to thank everyone once again for sharing your thoughts! @Rusty Empire : The entire building shown in pic is a single building, because of our inexperienced design it looks like disjointed:(:(. We just finished the painting of primer coating, yet to paint the final color. The pic you posted with color looks awesome, planning to paint the same color. I believe it would change the entire view of building @decoenthusiaste : The entire building shown in pic is a single building. Will post more pics in coming days, pls review it and share your thoughts. @emmarene : Right now I'm at my work place, so I don't have a main entrance pic with me. Will post it by this weekend. Please review it and share your valuable thoughts. @Chikka BangBang: That's gr8 idea, will think abt it. Thanks!
