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.

If I understand the seasons in India correctly, you have already been through the rainy season. Don't wait until the next rainy season to get the problem with your drainage fixed. Now will probably be the ideal time to get it fixed. Please get someone who will tell you what to do and then have the work done. The paint on that wall in your beautiful home will keep coming off!

A good beginning would be to replace the walkway up to the house. A new brick walkway or stamped concrete in the same color as the brick on the house will pull all of the elements of the exterior of your home together. I made my walkway 3 feet wide with 2 feet beds on each side of the walkway in stamped concrete. Create the walkway at a distance from the house in an organic natural flowing pattern up to the house with planting beds flowing beside the walkway. Take the brick right up to the from door. Soften the entrance to your home by opening the planting beds up by the house into large organic shapes. That's what I did with my home and it changed it dramatically! It's a lot of work but what a difference!

Modern houses like yours tend to be painted neutral colors. I'd go for white or off white with trim in different colors. I'd probably accentuate the horizontals, painting your porch railings a contrasting color. You can go to a website like SherwinWilliams, up load a better picture of your house and play around with color ideas. https://www.houzz.com/photos/texas-residence-contemporary-exterior-dallas-phvw-vp~1994082-Residence-contemporary-exterior-dallas https://www.houzz.com/photos/san-clemente-california-home-contemporary-exterior-orange-county-phvw-vp~2456325-CLEMENTE-California-Home-contemporary-exterior-orange-county https://www.houzz.com/photos/oakland-hills-residence-contemporary-exterior-san-francisco-phvw-vp~52742-Hills-Residence-contemporary-other-metro
