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!

this looks awfully cold ( color wise) and somewhat commercial - I would use more earthy warm beige stucco and use some wood rather than painting the lap board shown, break down the mass by selecting a mass ( such as the two story massing above carport and introduce some stone veneer for a more earthy look - check out modern house category for some ideas how modern facades are normally treated.

We may need more photos but the first thing I see is that the glass elevation is fairly contemporary, however, the gate and grate on the lower elevation deserves to have the horizontal lines of the upper railing. The entry door that now appears to be wood toned ought to be painted white to match the mullions on the other elevation OR be painted in a contemporary bright. Since the house appears to have a pale green/yellow on the stucco above, a great color to go with the pale lime for the front door would be turquoise, or purple. All the white that now has some gray (stucco repair) needs to get a fresh coat of white. Need more photos to do more.

If you want to remove the paint, you can rent a sandblaster and test it out; the main thing you want to watch for is if it is damaging the mortar. Otherwise, you could add sand to paint and either paint it all one color, or do a faux finish on each stone with a blend of several colors, I would start with one color base coat you want the mortar color to be and then move to the stones. Another idea is to call a stucco company and see if they can give you a smooth finish.
