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!

Hello Vinita, Is it feasible to build a roof cover structure with GI sheets or natural materials ? It is the best way to avoid the roof getting direct sun light and eventually heatup. Plants with clay pots also take away most of the sunlight. Terra cotta mud tiles are good cover them with gravel to avoid heat. Thanks, Nitin CORNERSTONE DESIGNS Bangalore.

vedikaseth Bombay rains are harsh! The one thing you can do is use flexible covers that work similar to roller blinds, and are transparent which allows the light to enter. There are many companies that offer such a product. Just choose one where the installation is easy and taking down the sheets is not an issue once the rains are over. Do keep in mind however that the water will still enter the balcony, you will simply be reducing the force of rains, and will require a water outlet.

Well All LEDs emit heat and if you don't provide a heat sink( moslty copper or aluminium) which helps dessisipate heat so that LED can work for a long time but I mostly see people use recessed light with false ceiling and I'm not a fan of false ceiling but I want recessed lighting so I can provide the holder and the profile in which the bulb gonna be placed while poruing concrete so that I don't have to drill later but I'm concerned about aluminium profile since they react with concrete.
